    text: The T100 actually has 8 colours in 320x200. Also the colour monitor, although having a propriety connector is compatible with a standard CGA - minus the intensity pin. Back in the 80''s I had no trouble converting the Toshiba monitor for a pc/XT. Can''t imagine why the opposite isn''t true.

    text: In case anyone out there is interested, I have the technical reference manual for the T100 which I''m happy to scan to a pdf if anyone is interested. Also I''m looking for a copy of the T-basic reference manual if anyone has a copy. Thankyou in advance. MSPWPGS at Gmail dot con.

      I''ve got a complete Toshiba T100 setup with the Dual Disk Drive and Monochrome Monitor and probably documentation. If anyone would like all this for their museum or whatever, I''d be happy for it to find a good home.

      It''s even got a custom high-speed RS-232 interface card that I made that is mounted in the memory expansion port slot.

The T100 was the US version of the Japanese PASOPIA computer. It was intended to be a professional CP/M machine.

It had a small built-in LCD screen (6 or 8 lines of 40 characters or 320 x 64 pixels in graphic mode). This LCD screen was an option (not built-in). It fitted into slots at the back of the keyboard/cpu unit.

There were 2 CRTs available: 13" monochrome (green), and 15" color with a proprietary RGB interface. The twin floppy drive was a separate box.

It was possible to plug a memory module into the slot under the flip-up cover at the rear right of the keyboard/CPU unit. That was the only way to add memory.
