Thanks, I'll do that. I'm wondering just what one could do with an modern 8-bit CPU with a well thought out ISA and has more then 8 registers like 16 or 32If you find the conversation here is coming to a close I would suggest heading over to Vogons. Check out the General Old Hardware forum. I hang out there and it's a friendly place full of people interested and knowledgeable about older hardware. Not to knock this place but it's geared more toward the newer stuff.
