I have a Electronicka MC-1502 it's basically a Soviet PC Jr Tandy copy. The PROM chip on the floppy drive controller has been damaged is there anyway to recover the code from the failed PROM the chip is a 82S126. If anyone has any experience with these machines or knows another solution please let me know. There were some replacement gerber designs posted on zx-pk.ru forums but they are no longer accessible. I rescued this and some other Soviet machines right before the tragedy in Ukraine started and would like to get this one up and running again fully.
