I flashed your PLA test program to an Arduino Uno and wired it to the PLA (8700-001) as declared and figured out that with a working PLA (Fujitsu 251064-01) everything looks OK but with the mentioned MOS 8700-001 I got LED flashes -> FAILED.

So if I put the "failed" 8700-001 to a working C64 everything is good! I have a video of the setup here: https://www.youtube.com/watch?v=KTHi8Ji6yds

Btw. any idea what could be wrong with this image after boot: https://imgur.com/a/6CjX6wW

Thank you.

I'm trying to run the PLA test using my Uno and have an issue with the diagram provided.

What exactly does this mean:
PLA F0/4 --- C2
PLA F1/5 --- C3
PLA F2/6 --- C4
PLA F2/7 --- C5

What is the F2/6, F2/7 and others exactly mean?

Thanks,

Hi,
just uploaded the c64 dram test to a ordinary mega2560 without any wires.
The test PASSes every time without an attached dram. How is this possible?

Thomas

Diagram (first half) shows:
A4 --- RAM A5 (Should show A4 --- RAM A4)
A6 --- RAM A7 (Should show A6 --- RAM A6)

Upload fails on MEGA if 3 exclamation marks are sent.
Change "Serial.println("FAIL!!!");" to be "Serial.println("FAIL!");"
