And another about very early computers that used microprocessors (before the Altair btw)
SO when I saw the Ebay auction I was quite amazed someone actually had one of these COSMACs. The Ebay seller I bought the "RCA COSMAC Microkit" used my site as a reference. I hate it when my web site is the only source of information on a computer or vintage historic computer item ... nothing else available on the web.
The Ebay COSMAC appears to be an originally-named "COSMAC" processor version, not the renamed CDP-1801s that you'd see in the 1976 trainer version.
I hope he includes some materials with the computer, he is from NJ and mentioned he had some knowledge of the providence of the RCA company. Stay tuned.
