i recently got an old Rack Computer which was used for Laser Control. Examination showed it worked with a terminal as I/o Device . It is named LasCom Laser Controller and is based on 6502 CPU's and built around 1984. the cpu boots but does not output any characters on the serial IO... a pity. the computer used a Tape drive as storage. but unfortunately i donnot find information about micro casette data drives. the controller has a sub d connector . the computer has a controller board based on the 6520 and a Rom named LasCom CAS.
i likt o use the controller as storage for the Apple Ii. Maybe anybody has information onthese drives.
i may take more
