CoCoGrey Hardware

The CoCoGrey board. This plugged into the 6847 socket in the Radio Shack Color Computer, and the actual 6847 was relocated to the socket on the board. So everything still worked normally for the computer's video output, but in addition, there is now a 16-grey level display available from the video output of this board. It was great for displaying reasonable B&W images such as ham radio SSTV images, SSTV use actually being the reason I designed it.

I laid the circuit board out by hand on a light table. The CoCoGrey schematic is here.
