👍 v.3 now without PHI2 selection, because the v6510 only works with buffered PHI2! 😉

Schematic

Parts

CPLD-Firmware: The .JED file can be uploaded with a JTAG-SMT2 Xilinx programmer (China) and xc3sprog

BEWARE: I got good CPLD's from China, but there are some XC9572XL FAKES out there!

I just got these 10ns cplds and they don't work - but I don't think 7ns is really necessary: V6510 bottom-photo

V6510 in my 250407 test-board: V6510 photo

For a WDC 65C02 you have to cut the small trace in the other solder jumper.
