Title A name given to the resource Microsystems International Limited (MIL) Collection Description An account of the resource In October of 1968, with $48 million package from the Canadian Treasury Board, Northern Electric transformed its Advanced Devices Center into a new company called Microsystems International Ltd. (MIL). In March of 1969, MIL opened its doors with its headquarters in Montreal and the manufacturing facility in Ottawa. The company's focus was to be on new  semiconductor technologies and products. In a short period of time, MIL acquired state of the art integrated circuit technologies and the second source rights to a number of products. The company's memory products, such as MF1101, MF1103, MF1701, or MF1702, and the MF8008 microprocessor, placed the company among the semiconductor leaders on the international market. Between 1970 and 1972, MIL developed and manufactured Canada's first microprocessor -- the MF7114. It also produced three microcomputers:  the CPS/1 system designed around the MF7114 microprocessor as well as the MOD8 and the MOD80 computers. The MOD8 microcomputer, developed in 1974, was based on the MIL MF8008 8-bit microprocessor. This computer (as well as its refinement -- the MOD80) consisted of the MOD8-8 PCB backplane mounted in an aluminum case. The backplane contained the Eprom programmer and nine connectors for the CPU, memory, interface, and I/O cards. The MOD8 computer and its MONITOR8 software were aimed at the development of the MF8008-based applications. To MIL's surprise, it was the North American computer enthusiasts who made the MOD8 a popular 8008-based microcomputer kit in 1975-1976. MIL's MF8008 Applications Manual was one of the most widely read early documents on 8-bit microprocessors. The MOD8 influenced other early microcomputer designs for the hobbyists' market such as the Mike2 computer from Martin Research or a range of C-MOD computers from Celetron Corporation which were sold by MiniMicroMart of Syracuse, NY. The company closed its operations in June 1975. However, MIL's demise seeded the Canadian high-technology sector with scores of semiconductor, computer, and telecommunications start-ups founded by former MIL employees. Acquisition: The artifacts have been donated to YUCoM by several individuals including  John Freeman, John Hackman, Kelly Hamilton, William Kindree, Mark Silver, Zbigniew Stachniak, and Candi Trefero.

The MIL MOD80 microcomputer had the same architecture as the MOD8 with the exception of the CPU module.

The MOD8 computer and its MONITOR8 software were aimed at the development of the MF8008-based applications.

Title A name given to the resource MICOM 1001 Digital Word Processor Subject The topic of the resource hardware: digital word processor Description An account of the resource Historical context (by Z. Stachniak) In 1967, Stephen Dorsey founded Automatic Electronic Systems (AES) in Montreal to develop electronic devices for industrial remote-control applications. Over the six years, AES developed, among other products, its own minicomputers (the AES-80 and AES-80C) and the world’s first all-in-one programmable word processor — the AES-90. Until the mid-1980s, digital word processors remained the company's main line of business, sold around the world. In the 1960s, office document-writing equipment was still dominated by various types of typewriters, ranging from purely mechanical to electric models, including those with digital storage for recording typed text, such as the best-selling IBM MT/ST (Magnetic Tape/Selectric Typewriter), which recorded edited documents on magnetic tape. These devices lacked displays and offered only limited word-processing functionality. None of them could be upgraded to newer versions; they could only be replaced with more advanced models as they became available. It all changed in the early 1970s, when several companies introduced dedicated text-editing equipment with displays for on-screen document editing and external storage. In 1972, Linolex Systems introduced its Model A while Lexitron offered the Videotype 911. In the following year, AES released its AES-90 Word Processor, and Vydec began selling its Vydec Text Processor. Although all these systems provided on-screen editing and external storage, several unique features of the AES-90 set new trends in the design of cost-effective text editing equipment. The most important of these was the AES-90 architecture and its software upgradability. The AES-90 was a standalone system that featured a CRT display, a keyboard, and two 8-inch floppy disk drives connected to a central processor. However, unlike the “hard-wired” solutions used in other early on-screen text-editing systems, the AES-90 processor was built around a general-purpose minicomputer (the AES-90C) running dedicated text-editing software. This design allowed for software updates, bug fixes, and adaptation to changing requirements without the need to purchase a new processor and discard the outdated one. For this reason, the ACS-90 was promoted as a programmable word processor and “a giant step into a new era of cost-effective written communication.” Within a few years, the office equipment market was flooded with similar video-screen text-editing products from companies worldwide—the Toshiba JW-10 Japanese Language Word Processor, announced in 1978, is one notable example—revolutionizing office operations. Although orders for AES-90 processors were piling up, AES faced significant difficulties with cash flow and attracting investor interest. Ultimately, the company came under the control of Innocan Investments Ltd., a Canadian financial organization specializing in venture capital for new and expanding firms, particularly those in high-technology industries. The Canadian Development Corporation owned 40% of Innocan, while other shareholders included the Air Canada Pension Fund, the Bank of Nova Scotia, and several well-established investment groups. Difficult relationship with AES financial backers led Dorsey to leave the company in 1975. Soon after leaving AES, Dorsey founded Micom Data Systems in Montreal. The company went on to manufacture a successful line of digital word processors, beginning with the introduction of the Micom 2000 in 1976. In 1978, Philips Information Systems of Toronto, a subsidiary of the Dutch office automation giant Philips NV, acquired 80% of Micom’s ownership. As part of the Philips corporate group, Micom gained access to Philips' extensive global marketing and distribution network. By the end of the 1970s, Micom had become a market leader, ranking first in sales in Canada and second in Europe. Its equipment was installed in numerous major organizations, from Air Canada and Washington Gas to NASA (with over 50 MICOM 2000 systems deployed). Micom's workforce grew rapidly, expanding from just five employees in 1976 to more than 1,100 by 1980. In 1984, the company relocated to a new facility in Saint-Laurent, Quebec, and began manufacturing the Micom line of Philips PCs in addition to its word-processing hardware. That year, Philips Information Systems recorded sales of $62 million, up from $38 million in 1983. Of that $62 million, approximately $42 million came from the sales of Micom word processors. Although Micom was more successful than AES Data in the 1980s, its word processing business was phased out by the end of the decade due to the global transition in the office-equipment industry toward microcomputer-based multifunctional solutions. Micom 1001 Released in 1980,  Micom 1001 word processor  was designed and manufactured in Canada.  It had built-in plasma display (one line of 40 characters) and a single mini cassette drive for external storage.  The QWERTY-style keyboard included editing function keys and tape storage control keys. The processor could be connected to a printer. Technical specifications CPU:  Zilog Z80 microprocessor, 8-bit; with Mostek MK3882N timer-controller; ROM: 16 Kb x 8 in  4 2732 EPROMs; display:  built-in LCD module, one line of 40 characters, controleed by the HD43160A LCD chip containing character generator and display memory ; keyboard: QWERTY-style, 57 keys; 10 function and control keys; external storage: single mini cassette drive; porrts: printer port.  Software Firmware stored in ROM.

Title A name given to the resource DY-4 Systems Collection Description An account of the resource DY-4 Systems Inc. was an Ottawa-based high technology company founded by four engineers Garry Dool, Terry Black, Kim Clohessy, and Steve Richards in 1979. In the early 1980s, DY-4 designed and manufactured a variety of products including microcomputers (the ORION series), graphics terminals, and STD bus board level products (including single-board computers). In the second half of the 1980s, the company shifted its attention to the development and manufacturing of products for harsh environments. A wide range of products based on VME bus architecture was offered for applications in areas such as air traffic control, tactical command, control and communication, flight management for airborne applications, ground tactical support, process control, and robotics. The products included single-board computers, memory modules, intelligent peripheral controllers, special function modules, and I/O modules. By 1993, when DY-4 went public, the company was already a technological leader in the ruggedized embedded computing market providing open systems board-level products, support systems and related software to harsh environment systems integrators. DY-4 products found their way to new generations of tanks, submarines, airplanes and spacecraft in many countries around the world. The company entered the 21st century retaining its premier position as embedded computing solutions provider in the defense and aerospace industries. In 2004, after a series of acquisitions, DY-4 business was bought from Solectron (Milpitas, Ca) by defense contractor Curtiss-Wright Corp. (Roseland, N.J.).

Title A name given to the resource Microsystems International Limited (MIL) Collection Description An account of the resource In October of 1968, with $48 million package from the Canadian Treasury Board, Northern Electric transformed its Advanced Devices Center into a new company called Microsystems International Ltd. (MIL). In March of 1969, MIL opened its doors with its headquarters in Montreal and the manufacturing facility in Ottawa. The company's focus was to be on new  semiconductor technologies and products. In a short period of time, MIL acquired state of the art integrated circuit technologies and the second source rights to a number of products. The company's memory products, such as MF1101, MF1103, MF1701, or MF1702, and the MF8008 microprocessor, placed the company among the semiconductor leaders on the international market. Between 1970 and 1972, MIL developed and manufactured Canada's first microprocessor -- the MF7114. It also produced three microcomputers:  the CPS/1 system designed around the MF7114 microprocessor as well as the MOD8 and the MOD80 computers. The MOD8 microcomputer, developed in 1974, was based on the MIL MF8008 8-bit microprocessor. This computer (as well as its refinement -- the MOD80) consisted of the MOD8-8 PCB backplane mounted in an aluminum case. The backplane contained the Eprom programmer and nine connectors for the CPU, memory, interface, and I/O cards. The MOD8 computer and its MONITOR8 software were aimed at the development of the MF8008-based applications. To MIL's surprise, it was the North American computer enthusiasts who made the MOD8 a popular 8008-based microcomputer kit in 1975-1976. MIL's MF8008 Applications Manual was one of the most widely read early documents on 8-bit microprocessors. The MOD8 influenced other early microcomputer designs for the hobbyists' market such as the Mike2 computer from Martin Research or a range of C-MOD computers from Celetron Corporation which were sold by MiniMicroMart of Syracuse, NY. The company closed its operations in June 1975. However, MIL's demise seeded the Canadian high-technology sector with scores of semiconductor, computer, and telecommunications start-ups founded by former MIL employees. Acquisition: The artifacts have been donated to YUCoM by several individuals including  John Freeman, John Hackman, Kelly Hamilton, William Kindree, Mark Silver, Zbigniew Stachniak, and Candi Trefero.

Title A name given to the resource MIL MF7114 microprocessor Description An account of the resource Historical context (by Z. Stachniak) The MF7114 was an early 4-bit single-chip microprocessor designed and built by Microsystems International Ltd. (MIL) of Montreal between 1970 and 1972. It was the first microprocessor designed and manufactured in Canada. The MF7114 has its roots in the development of Intel's first single-chip central processing unit (CPU) -- the 4004. Before it was given the `MF7114' designation, the chip's general architecture was called the Intel 4005 and the purpose of its development was to backup the 4004's project, to fabricate a simpler general-purpose microprocessor in case of the 4004's fiasco. When in early 1971 the design work on the 4004 chip resulted in silicon wafers with a sufficient number of fully-functional CPUs on them to permit the chips' fabrication at the target cost, Intel abandoned the 4005 project. MIL on the other hand, continued the 4005's development and, by mid 1972, had its own 4-bit microprocessor -- the MF7114. MIL marketed the MF7114 as a CPU for stored program controllers.  In 1973, the company designed an MF7114-based  controller board to demonstrate the use of the chip to control the Singer Telerex 30  PMI Matrix Printer. The company also used the MF7114 to design a 4-bit microcomputer -- the CPS-1 (also referred to as the CPS/1, MPS/1, and MC-1). The computer was offered in two  versions. The first one was a single-board version. The board included the MF7114 CPU, clock, 4Kb of memory, and 16 I/O ports including a TTY interface. The second version was a  modularly designed hardware that included a chassis with backplane bus for system's expansions, a CPU and memory board, a power supply, a programmer's console, and the PROM connector to the PROM programmer. Designed in 1973, the CPS-1 was the first microprocessor powered computer built in Canada. <h4>The MF7114 Specifications</h4> <ul> <li>data bus - 4 bit, bi-directional</li> <li>address bus - 12 bit</li> <li>communications bus: (COMBUS) 21 bit, included 16 lines of data and address buses plus 5 control lines</li> <li>clock speed: 0.9 microseconds per cycle</li> <li>on-chip registers: accumulator (AC, 4 bit), program counter (PC, 12 bit), data pointer (DP, 12 bit), overflow register (OF, 1 bit)</li> <li>virtual (working) registers: eight 4-bit and eight 12 bit registers</li> <li>number of instructions: 58, executed in three to five cycles</li> <li>supporting chips: the MF1601 ROM and MF7115 RAM</li> <li>packaging: 24-pin DIP</li> </ul> <h4>Museum Holdings</h4> A promotional paperweight with a 7114 chip set consisting of an MF 7114 CPU, an MF1601 ROM, and an MF7115 RAM.

Title A name given to the resource Bell Alex Display Phone Description An account of the resource Bell Canada ALEX tetetext service has its roots in the popularity of teletext systems (such as the French Minitel) and in Bell's Integrated Office Systems strategy, developed in mid 1980s, to integrate office systems with communications. Bell ALEX provided on-line data services through Bell's commercially available packet-switching data network called Datapac. ALEX service required a dedicated  terminal (rented from Bell) to be installed at a customer's location (later, the service could also be accessed using home computers). The ALEX terminal was designed by Norpak Corp. of Kanata, Ontario and manufactured by Northern Telecom. As opposed to text-based teletext  services such as Minitel, the display of ALEX terminal was implemented in compliance with internationally acclaimed NAPLPS standards (North American Presentation Level Protocol Syntax) first developed for the Canadian Telidon system. The ALEX service was officially launched in 1989 in Montreal (following the 1988 trials) and soon after in Toronto. Initially, the services in categories such as communication, entertainment, games, education, government, and shopping were offered. By September 1990, there were over 580 services available in Toronto area. The service was discontinued in 1994.

Title A name given to the resource Northern Electric—Nortel Networks Collection Subject The topic of the resource <img src="http://museum1.eecs.yorku.ca/www_decorations/Nortel_Logo.png" alt="Nortel_logo" width="25%" height="25%" border="0" /> The collection is dedicated to the corporate history of  Northern Electric and Manufacturing, Northern Electric, Northern Telecom, Bell-Northern Research, and Nortel Networks. Description An account of the resource Northern Electric and Manufacturing Company was founded in Montreal, Quebec, in 1895. It's main business was the manufacturing of telephone equipment for Bell Telephone Company of Canada. In 1914, the Northern Electric and Manufacturing Company merged with the Imperial Wire and Cable Company of Montreal to form the Northern Electric Company.  Although the new company's main business continued to be telecommunication equipment, Northern Electric also ventured into consumer electronics market manufacturing radios, television sets, console radio-phonographs, hi-fi amplifiers, and so on. In 1971, Northern Electric and Bell Canada formed Bell-Northern Research (BNR) — an Ottawa-based telecommunications research and development company. Around the same time, Northern Electric introduced its first electronic  PBX (Private Branch Exchange — a private telephone network used within a company or organization) named the SG-1. Four years later, BNR introduced the  SL-1 PBX  which was the world's first all-digital PBX aimed at medium-sized businesses.  In 1976, Northern Electric Company changed its name to Northern Telecom Limited and the company focused its operations exclusively on fully digital telecommunications products.  Northern Telecom was the first company in its industry to deliver a complete line of fully digital telecommunications products. Its SL-1 became the world’s most successful PBX and, by 1991, the company  was the world’s largest PBX supplier offering its Meridian communication systems line. In 1998, the company's name was changed to Nortel Networks to emphasize its focus on networking solutions for telecommunication over the Internet and other communications networks. In 2009, the company filed for bankruptcy protection. Abbreviations: <ul> <li>BNR: Bell-Northern Research Ltd.</li> <li>WC: W.

Title A name given to the resource Northern Telecom Displayphone Description An account of the resource Historical context By Z. Stachniak with input from D. Cuddy In February 1981, telecommunications giant Northern Telecom announced the Displayphone – a landmark office automation product designed to integrate voice and data in a convenient, easy-to-use desktop unit. The January 1988 Datapro Research Corporation's report described the Displayphone as a device that:    opened up the integrated voice/data terminal market [...] The first    commercially available device of this kind, the Displayphone [...]    attracted a great deal of attention in the computer industry, particularly    among workstation vendors. Many vendors were interested in    bringing their products to executive desks; thus the Displayphone    was a factor in the emergence of a new class of equipment  –    executive/professional workstation. The Displayphone was developed by Bell-Northern Research in Ottawa and manufactured by Northern Telecom. Its first model–the NT6K00–was a small desktop terminal with a handset, speakerphone,  an integrated 300 bps modem, built-in 7-inch monochrome display, dial and screen pad, and five soft keys. A retractable QWERTY-style keyboard was stored within the unit's base. The device could operate with two independent phone lines for simultaneously handling voice and data calls which allowed users to talk on the phone while accessing and viewing information from remote dial-up data services. In addition, the unit could be used as a data terminal connected to a local computer via the RS 232C port. It could also access database services via an external modem and drive a printer through a parallel I/O interface. The Displayphone featured a 90-number telephone directory, on-hook as well as automatic and hands-free dialing, last number redial, a recall work list and call hold. Other features available were a continuous day/date clock, a telephone call timer,  and a reminder service that brought messages to the user's attention. The user interace was designed for ease of use, with context-sensitive prompts displayed on the screen and soft keys that led the user from one operation to another. Between 1981 and 1986, Northern Telecom released several models of and upgrades to the Displayphones, including the PLUS (released in 1984) and the 220 (offered in October 1986). Another variant, the SL-1 Displayphone, when designed to access the voice and data capabilities of Northern Telecom's popular SL-1 PBX. By the mid-1980s, Northern Telecom had already faced competition from other vendors including AT&T, Davox, InteCom/Wang, and Rolm. Nevertheless, the Displayphone continued to have the largest installed bases of any of the competing products, which, according to the 1988 Datapro Research report, was at around 50,000 in 1987. Following the success of the Displayphone in the enterprise market, NT proceeded to develop its successor–the Meridian M4020 Integrated Terminal–which was released in 1985. Instead of a pair of analog telephone interfaces, the M4029 connected to the network over an integrated 2.56Mbps digital interface.

Title A name given to the resource Early Computing at York University -- Photographs Subject The topic of the resource computing infrastructure: photographs Description An account of the resource Historical context: Academic computing in Canada started to develop in the early 1950s. The first commercial digital electronic computer—a Ferranti Mark I (nicknamed FERRUT)—was installed at the University of Toronto in 1952. For several years, FERRUT was the only digital electronic computer operated by a Canadian university. In 1957, the University of British Columbia installed its first computer—the ALWWAC III-E—and the University of Alberta its LGP-30 computer. York University was established in 1959 at a time when there were just 40 electronic digital computers working in the entire Canada. However, it was not until October 1966 when York installed its first computer—the IBM System \360 Model 30—and established its Computation Center. The computer was replaced by a more powerful IBM System/360 Model 40, and then by Model 50 in the following two years. In 1971, York installed an IBM System/370 Model 155 — a computer from a new line of IBM mainframes. This computer, in turn, was replaced by a high-end Model 158 in the mid 1970s. The photographs in this collection were taken in the early to mid 1970s. They depict the computing room of York's Computation Center as well as students'  keypunch room.

Title A name given to the resource Mathatron calculator at York University Description An account of the resource Historical context (Z. Stachniak) The commercialization of the transistor in the first half of the 1950s had a dramatic impact on the decade-old computer industry. The all-transistor computers were offered as early as 1953 and, by the end of the 1950s, all major computer manufacturers were building transistorized machines. Similar shift to solid-state technology was made across consumer electronics industry (for example, in the mid-1950s, all-transistor radios quickly began to replace large and bulky vacuum tubes-based radio sets). Despite clear advantages that solid-state electronics had to offer to calculator manufacturers (if built, transistor-based calculators would be smaller, quieter, more versatile, and virtually maintenance free when compared with the traditional desktop electro-mechanical calculators), the calculator industry was much slower in adopting the new technology. Calculator manufacturers were quite reluctant to venture into electronics when no competitors, even those with electronics divisions (such as Olivetti, Burroughs, Sony, and Canon), were putting any electronic calculators on the market. They were simply unwilling to go against their main core products that still delivered corporate wealth and prestige, they had no desire to invest substantial resources into concurrent divisions of electronic calculators that would internally compete with their best-performing divisions of electro-mechanical calculators. It was not until the early 1960s that the first solid-state calculators appeared on the consumer market and almost instantly gained consumer acceptance. While most of the early electronic calculators supported only rudimentary arithmetic operations with, in some cases, one or two memory registers for storing intermediate results, several firms introduced calculators with functionality that went far beyond that. The execution of short sequences of instructions (programs) was the most notable of these new features. Programs for such calculators could be keyed-in by an operator or read from an external storage media (such as punch cards) and, then executed as many times as desired by a single press of a key. Mathatronics Mathatron Massachusetts-based company Mathatronics Inc. introduced its programmable calculator Mathatron in 1964. In comparison with ordinary calculators of the era, the Mathatron offered programming of complex mathematical formulas. The calculator was equipped with a printer that recorded entered programs as well as outputs of their execution. A special learn-repeat feature of the Mathatron allowed to store a program and reuse it as many time as required during a calculation session. In March 1964, Computers and Automation reviewed the Mathatron referring to it as a "unique desk-top size electronic digital computer." Mathatronics sold several models of its calculator: <ul> <li>Model 4-24 with 4 memory registers and program length of up to 24 steps,</li> <li>Model 8-48 with 8 memory registers and program length of up to 48 steps,</li> <li>Model 8-48S (Statistical Model) with 8 memory registers and program length of up to 48 steps,</li> <li>Model 8-48E (Civil Engineering Model) with 8 memory registers and program length of up to 48 steps,</li> <li>Model 8-48M (Mathematician' Model) with 8 memory registers and program length of up to 48 steps.</li> </ul> Models 8-48 offered several built-in scientific routines that could be selected using a built-in dial and pressing the "ENTER" switch located next to the dial. These routines could be executed separately or incorporated into programs. Mathatron at York University In the mid-1960s, York was rapidly growing and establishing new key departments. In 1965, Ralph W. Nicholls joined York University from the University of Western Ontario to form a new Department of Physics. In the same year, he became founding director of York's Centre for Research in Experimental Space Science (CRESS, later renamed the Centre for Research in Earth and Space Science) that quickly gained prominence in North America. Unfortunately, York's first computer--the IBM System/360 Model 30--was only installed in November 1966 and, until then, CRESS members had to rely on calculators and computer resources offered by the University of Toronto. It was Nicholls who brought a Mathatron to CRESS. The calculator served calculating needs of both faculty and graduate students throughout the 1960s and 70s. It's use was under strict control. The instructions attached to CRESS' Mathatron read: <ol> <li>The use of this machine is restricted to CRESS staff members.</li> <li>CRESS Graduate Students must get permission from Dr. G.R. Hebert to use machine until they have indicated some proficiency in its use.</li> <li>Others must have the explicit permission from Dr. G.R. Hebert each time the Mathatron is to be used.</li> <li>Please fill in log book every time the Mathatron is used.</li> <li>Do not remove manuals from this location.</li> <li>In case of doubt regarding the operation of the Mathatron consult a) manuals b) G.R.

Title A name given to the resource DY-4 Systems Collection Description An account of the resource DY-4 Systems Inc. was an Ottawa-based high technology company founded by four engineers Garry Dool, Terry Black, Kim Clohessy, and Steve Richards in 1979. In the early 1980s, DY-4 designed and manufactured a variety of products including microcomputers (the ORION series), graphics terminals, and STD bus board level products (including single-board computers). In the second half of the 1980s, the company shifted its attention to the development and manufacturing of products for harsh environments. A wide range of products based on VME bus architecture was offered for applications in areas such as air traffic control, tactical command, control and communication, flight management for airborne applications, ground tactical support, process control, and robotics. The products included single-board computers, memory modules, intelligent peripheral controllers, special function modules, and I/O modules. By 1993, when DY-4 went public, the company was already a technological leader in the ruggedized embedded computing market providing open systems board-level products, support systems and related software to harsh environment systems integrators. DY-4 products found their way to new generations of tanks, submarines, airplanes and spacecraft in many countries around the world. The company entered the 21st century retaining its premier position as embedded computing solutions provider in the defense and aerospace industries. In 2004, after a series of acquisitions, DY-4 business was bought from Solectron (Milpitas, Ca) by defense contractor Curtiss-Wright Corp. (Roseland, N.J.). Acquisition: The objects in the collection have been donated or acquired from: Dave Dunfield, Mati Sauks, and Zbigniew Stachniak.
