Jim Wilson designed the board for Wintek Corp, which he founded with Professor Paul Wintz. The board had a 1024 bytes of uv-eraseable rom and 512 bytes of ram. Ward Cunningham developed the first version of the Morse Code Teaching Machine on the very board shown above using only the ram for both program and data storage. The large ceramic part is the processor. The large plastic part is a dual serial adapter used to talk to a video terminal also made by Wintek. The small ceramic parts are the ram and rom. The empty socket is for a parallel port adapter which I never used.
This is the source code for this machine:Single Chip Morse Teacher, Personal Computers.
