Cool stuff, Stuart.

I've got minimal breadboard projects for the TMS9995 and 99110 on my web site - www.stuartconner.me.uk.

If it's specifically the TMS9900 you want to use, then there's a fair bit of wiring to do because you need two RAMs and two EPROMs for the high and low bytes, and you'll need to program the EPROMs in pairs. Will also need the TIM9904 clock generator. Perfectly do-able, but the 9995 is easier if you're new to this sort of thing.

Wouldn't bother trying to isolate or unsolder a 9900 - they're normally available cheap on ebay (might want to avoid Chinese sources), or someone might have a spare you could have. If you're in the UK, I've got some spares somewhere.
