Hi everybody!
The DIAG 264 test cartridge indicates the following error.
Which RAM can be corrupted?
Thanks!

Could be any, the diag does not tell us which bit(s) are bad. Go to MONITOR and put some 00, FF, 55 and AA bytes into the F900 area to see which bits are stuck or crossed. Use the flag at 7F8 to get RAM if necessary (put 00 or 80).

Hi!
The PLA and BASIC ROMs were defective.
RAMs all work!
