I just saw there is a link to some of the specs ! Doh! I'll take a look there.

I'm still amazed, but feel a bit stupid for not reading the link first !

So this has 1kb ram, 8kb ROM (programmable I guess) and its outputting high-res animated colour graphics and sophisticated (4 mins?) music - I would say three channels (maybe four?) including white noise , complicated envelopes (arp'd notes, pitch bend..) and fiddly solos.

Is this all in just 8kb????? How have you managed this??? Does the micro-controller offer a lot of pre-built counters and timers and blitter stuff ?
Are you using compression to fit all this in ???

This is absolutely amazing....
