Wayne Downer and I squeezed the Morse Code Teacher into a then new one-chip computer, predecessor of the 8051.
I translated the teach algorithms to the chip's instruction set while Wayne wrote auto-baud serial functionality using the few remaining unused bytes in the chip's 64 bytes of available ram.
We sent a copy to Heathkit suggesting that they might make it a kit. They took their time returning it but declined to go forward.
Wayne later added a single character display so that he could practice code without having a terminal on hand.
