All —
While looking for 6545 CRTC schematics, I came across Hans’ archive of Elector 6502 stuff. Has anyone done reproduction or recreations of those? I really like the design so maybe I can do one.

Hello,
Can you please post the link to Hans' archives?
I did make a board with the 6545 to the schematics of Elektor.
Most TTL Glue-logic is replaced by a Gal22V8, but I've not made the content yet.
The board is 100 x 100mm and has a bus connector that fits a design by a 8085 system.
Not tested yet, but I'd be willing to share the design. (Kicad version 5)
The boards have been produced and I may have one to spare. (I'm in the Netherlands)
BR/
Guus
P.S.
8085 design by Craig Andrews.
QFP-PCB for this routed by me.
Also made the fitting 6502 board, same bus and schematics of "Elekterminal"
Againg, not tested and Glue logic in Gal22V8, no content yet.
