Graymark 809 Trainer
- I picked this up today from the curb. It consists of a three-ring binder, with a SBC inside (made to fit a three-ring binder,) and its technical manual. After a quick glance at the board and the manual, it uses an Intel 8085, has 2k battery backed static ram, 8k rom, and RS-232c interface. It has an Atari 400-style keypad for hex and commands, as well as 8 switches for data.
Anyone know when it might be from?
Thank you for checking. Do you have any information about the original COSMAC 1801 computer? This as far as I can tell was the first computer-ish device based on the COSMAC processor.

Mother donated all of Dad's papers and prototypes to the David Sarnoff Library, so I only have a few things related to the programs I wrote and sold to RCA for the VIP and Studio II.Try e-mailing again at this address (minmax_3512@...). I'd be happy to correspond with you.Joyce
