Details for those who are curious follow in summary:
The complex circuit board was my own Motorolla 56000 DSP designed board with very fast A/D and D/A units. The Main control for the keyboard and display was using a 68331 based microprocessor circuit board I designed while working at Hewlett Packard and can be seen off to the right of the above picture.
