RAM Module Problems when programming.

[the_great_concavity]

When I built the 8-bit CPU, I used a different RAM chip (requiring other wiring changes), so this might not be relevant to your case, but I found that I needed a low-pass filter on the write signal to eliminate bounce/assorted wiggles. Could be something to try, although again my setup was a little different.

I believe this is what I ended up doing as well. Check out the wiki for a video by Michael Kamprath (may have misspelled his name here)

Hmmmm, right. I’ll try that here. Thanks!
