I assume most of us have never seen a C900. ?I need to google it, as I'm curious as to what it actually is.

A long time ago someone sent me some C900 disks, allegedly. I probably should find them and image them (I didn't have the set up for that back then and they're probably in the mess I call my stock closet). I don't have a C900 myself, though, so I can't even guarantee that's what they're for or that they work.

They ditched it when they bought amiga and sent all the prototype machines to a scrap company. So that would make them very rare. It also ran Coherent which was a pre-linux attempt to recreate a non-unix unix. I used to run it on my 486 laptop. It worked great. Good luck finding that software now. Although I'm sure a crazy collector out there has it. As for the keyboard, if a PC keyboard doesn't work, you might want to try one from an amiga 2000. They had the same connector, but were not PC compatible. For the video, I'd just plug in any old VGA multi-sync monitor. 1024x800 just sounds like 1024x768 with some overscan. As a side note, I'd love to have that case for a hacking project. But such a thing would be unforgivable if the motherboard weren't a total loss. brian

But it looks as though this machine and the amiga 2000 might have been designed at the same place in germany. The c900 case also looks very much like an amiga 2000 case. If the same engineers were used for the two projects, they could have easily taken the keyboard circuit from the c900 and used it in the 2000, maybe even reusing the keyboards on the 2000 that were originally intended for the c900. 2000 keyboards are as plentiful as the 2000. Getting a keyboard should be easy, although you may have to buy a 2000 to go with it. :-) Does anyone know if the commodore colt PCs use standard PC keyboards or something proprietary like the amiga keyboard? brian

As far as i know, the Amiga and the C-900 have different roots ... ... the Amiga was developed in the USA (Commodore bought the company "Amiga"), whereas the C-900 was developed mostly in Germany

The first version of the A2000 was designed by a group in Germany. It shares much of the >A1000 design, integrating several parts of the motherboard design.

The A1000 and A2000 keyboard interfaces use the same voltages and protocols. ?The difference is that the A1000 used a handset jack (like a narrow RJ-11) and the A2000 used a DIN5. ?A simple mechanical adapter cable allows you to use one keyboard on the other computer (I have one that lets you use an A2000 keyboard on an A1000).
