I just read your question about looking for software , spec CDOS, for the cosmac. Well I own a cosmac since 1983 but it's standing in the corner for a long time now. I have to gear up the poor thing and see if I can make a copy of the old floppy's. There are also a set of different cosmac cards and the cosmac ICE in a separate suitcase even all documentation and schematics are complete as far as I know. If I can help or If anyone wants to buy the whole system. Send me a proposal. Paul: pe.bosboom(a)hccnet.nl
