Wince Control Module with 6800 cpu and 512 bytes of RAM.
The original version of Morse code program was written in 1976 for the Motorola 6800 microprocessor. This was in the early era of personal computers, then a hobby item.
I tested the algorithms by programming a Morse Code Student which I ran on the CDC 6500.
I tested the finished program by teaching myself to touch-type on a keyboard placed upside down. This took about an hour and a half.
Each new home machine of the era came with a new and different microprocessor. I hand translated the assembly language to run on a variety of these devices.
I translated the algorithms to Pascal. Jim Wilson translated the Pascal to C which has gone through a number of versions and is still distributed today. website

Learning to hear letters in morse code requires practice at auditory distinction well suited to mechanical instruction. However, the obsolescence of the task has prevented ongoing investment in morse teaching technology. Could this inattention make learning morse an excellent testbed for advanced learning mechanisms?
