Re: 6502 CPU Schematics

Really? That does tend to agree with what I saw on the die. Nothing I
could identify as RAM/ROM or anything segregated in to sections like a CPU
is. I just assumed I was missing something. Maybe it's a bit simpler of a
device then I thought - just a simple ASIC.
What's your opinion of a MFM Floppy Controller then? Here's a link:

Think this would also an ASIC?

Good idea. Kind of what I was thinking - that I should be able to identify
some similar items between both devices.
Thanks for the input!
