Im very surprised this worked… #micropython test, less than 200 lines that I wrote in 1 hour.
Almost as much time it took to wire this monstrosity…
Will upload it on a new repo for peer review and some help with #rp2040 machine mem functions, but this seems to work just fine and the #sram (UT62256CSCL-70LL ) is healthy
Hastily pushed everything here, in case someone is interested to see how it looks like....

Edit : now public - I always forget about that....
