6502 chip

[Don.F.Broadus at ucm.com]

Great Stuff ! I would like to build a Z-80 trainer my self, if you have any
bare bones Z-80 info I would appreciate it.

 
Thanks

	If your realllly curious about what computers looked like back then
-- this
	guy designed and build one using ttl.
	http://www.iinet.net.au/~daveb/simplex/simplex.html
	however, note that IC were newfangled critters back in the 60s.
Imagine
	doing this all with transistors and core memory, not with neat
little ICs
	that have it all build in. Somebody posted a NASA page that
described the
	details -- scary what they did. The 6502 is a real supercomputer
compared to
	what they had available. 

	BTW, the 6502 on a AIM65 was the first micro I got to use/program
and was a
	very good processor for its time. You would be surprised to find out
just
	how many 4bit and 8bit micros are still in use for embedded systems.
My
	personal preference is Z80 and CPM.:-)  Simple and easy to use -- at
the
	time.
