Back in about Feburary 2006 issue of "Elektor", an article pertaining to the 6502 and its history contained a link https://people.freenet.de/dieter.02/m02.htm where this fellow had built a CPU from TTL gates and EPROMS that behaved like a 6502.
What I found even more interesting is he had built another CPU using transistors https://people.freenet.de/dieter.02/mt15.htm.
The schematics themselves for the MT15 are not entirely complete, the missing bits are incorparated in the many pages of explanation about how to design and build a CPU from nothing. I found it very educational and thought some of you may also find it interesting.
