Three #W65C02 to 6502 adapters. The top two use buffers on control and data lines (one uses ACT, the other HCT).
The last one, the newer, uses nothing and just adapts the pinout and adds a pullup.
Should have some time to test them on a real #VIC20 relatively soon.

I have experience of the #vickytwenty not liking the first two too much, but actually, it did not like even an original DIP W65C02S6TPG-14, while it did work with a W65C02S8P-10.
It's probably just an issue with the timings of the ICs used to build that machine, hence my intention to test on an original VIC.
