I've been a computer engineer for 38 years so I don't
mind programming. My digital waveshape generator was
built to plug into a proprietary microcomputer bus that
was similar to STD bus. All the control such as loading
the RAM and programming the counters was done through
that bus by a 6502 microprocessor.
