I still have the voltage monitor parts laying around. I want to test the circuit with a small drop-in PCB.

If I was going to enhance this design, I would replace the 68008 with a full 68000
I would also replace the almost-impossible-to-get SID chips with something easier to get. Maybe you could use a Yamaha YM family sound synthesis chip and some sort of raw DAC chip to handle sound effects and percussion and the things that the YM cant really do.
Such a combo has been seen on all kinds of consoles and arcade boards and I bet the YM chips are easier to get than SIDs.
For sound... There is the SwinSID which claims to be a drop-in replacement for the SID. My actual design went with the SID as I prefer it's sound over OPL chips (I have a YM262 OPL-3 laying around)
And I wasn't thinking OPL for the sound, I was thinking of a sound system more like that used in many arcade games that used a YM2151 FM synthesis chip and another chip to handle raw sound samples (used in the arcade games for sound effects and percussive samples that the 2151 couldn't do)

Impressive work, indeed! Please, be undeterred - this (momentary) small interest comes from the fact, that you have no advertisement at all. I'm interested in such projects since almost two years, and only yesterday - by accident - found your site. Have you considered adding your pages at least to Google and Bing, using a few significant keywords?
