6502 Build
This is it, a completed build... well hardware-wise. All I need now is to concentrate on the software side. It will be quite a challenge, as I haven't programmed in assembly for 30 years.

But I find myself wanting and yearning to have a good start in a new hobby, micro-electronics. And what better way than to start building an 8-bit microcomputer. And yes, I do dabble with microcontrollers also, so I have a good start. When I was in school in the late '80s I learned to program on the 6809 in assembly language on a single board computer (SBC). My initial thought was to recreate the aforementioned SBC, but the availability of parts is diminishing. In comes Western Design Center , makers of the new WD65C02 chips, still in production today. Off the shelf components is important to my endeavor, in case I want to replicate my design. Trying to scrounge vintage and obsolete parts is not part of the plan. So, welcome to my insanity project, keep in touch, an...
