I was lucky enough to get a PEB locally. It only came with the interface card. I sourced a 32k card online listed as untested. You know what that means
I have finalgrom and a tipi32k sidecar. I found a memory tester cartridge file online and ran that against the card. Upper block is testing bad. There was another memory tester program I found on Atari age that used a minmemory cart. Problem is the tipi is not happy with the memory cart and I can’t use it to upload the file to the cart.
Any suggestions on how to test further. I’m hesitant to probe in the peb with the scope because it’s awkward but that may be the only option. Unless I just remove all of the upper ram chips and socket and replace. It’s all MOS branded ram should I just replace them based on that fact alone
