A590, EEPROM instead of EPROM, possible? - Page 2

I did check it but I forgot the exact version, but it was reporting v40.something.
Next time I turn it on I will report exact version.

Found this thread and thought of asking here rather than open a new one.
I just got TL66II, and downloaded Xgpro, connected an ATMEL AT28C64B and used some of the options like, Erase, Read and Verify. Everything seems to be working fine.

Now, ofcourse, would like to burn the A590 roms. I have these in two files;

a2091PDMA-07.U12
a2091PDMA-07.U13

However when I open them I get the "File Load Options".

I have tried to leave everything as default and use the Program option but I get an error:

Code:

ERROR! CODE Address: 0x000000 Buf_Val:0x93 IC_VAL:0xFF

When I read after this it reads ok, but content is no longer 0xFF (clear). I erase again, read again. So I am guessing I am not selecting the correct options from the "File Load Options" screen.

Anyone knows what options I need to select here? If in the mood and tell me also why it would be nice to learn something new

Hmm, found on another forum it works when selecting CAT28C64B. Tried it and it worked.
