I am urgently searching for:
1. The bill chip (CSG/MOS 4567), as this one is missing.
2. C65 Rev5 hardware, as this would best for reengineering because it was the last Rev. as far as I know.
3. Any C65 hardware.
The goal is rebuilt it. I contacted the guy that rebuilt the C65 board and sold it last week on ebay. So the Board (Rev 2a/b) is already rebuilt. Now the hard part is reengineering the Chips.
I am also looking for people that also might have interest in this project and could help. Not only having C65 hardware but knowledge about rebuilding logic from chip layer photos as well as knowledge in reengineering would be awsome. I cannot go to a fab with the bare masks of the chips, they need the whole design done in their development environment, eg. x-fab, for creating the chips.
Why not better finishing the C65 late than never.
Bye,
Andy

Great idea and a fantastic project to tackle on. I am not sure if you find
much of a support here, though. I did some reversals (on a much smaller
scale - e4aws.silverdr.com) and could possibly help with PCBs, but that
part is mostly done as you wrote. Unfortunately I never decided to pay a
couple thousand for a hardware pieces of the 64dx..

======================
You might try www.6502.org as another source of information. Regular
participants include some who are involved in the Visual 6502 project
(www.visual6502.org), which started by de-layering the CPU to determine how
it works. Others are involved in building their own 6502-based computers, so
there's a lot of talk about how to build hardware that works. Still others
like to extend the 6502 design to 16- and 32-bits, so there's a lot of talk
about programmable logic chips and the tools to use them.
