Description

The NABU 1100 system was manufactured by NABU Manufacturing Corp. in the early 1980s. The system consisted of the the NABU 1100 computer (designed at Toronto-based Andicom -- one of the companies amalgamated into NABU) and the NABU 404 display terminal (designed and manufctured by Volcer-Craig Ltd. -- another Canadian company merged into NABU). Apart from being sold to Canadian customers through the Ottawa-based Computer Innovations retail stores (which become part of NABU as well), the system was internally used as software development platform for the NABU Network -- a new cable TV-based delivery method for software and information using world's first cable-ready computers.

The NABU 1100 computer hardwer was hosted in a large cabinet with casters on it for manoeuverability. A drawer at the bottom of the cabinet was provided to store software and manuals.
