It could also be a problem decoding addresses so the ROM content is valid but the ROM addressing is faulty, so it reads mush?
I don't have a manual unfortunately.
I am not sure as it seems to read the ROM contents ok 'ish as it displays the ROM names at the boot page. It only seems to have issues with
the CST Thor ROM (which has a checksum facility) and the serial ROM.
I was wondering about the RAM management as sometime the display is not 100% correct with info in different places and would the ROM
checksuming be done in RAM too... Maybe a ZX8301 issue?
It says to disable the RAM on the expansion board by shorting pin 9 of the PAL, which I did, buit that made no difference.
