reprogram Eprom Mephisto MMIV

Post by cakepanda »

Hello

I have a mephisto modul MMIV which appears to have a fault (I think) with its Eprom.

Looking on ebay, I have seen various cheap Eprom programmers and wondered if it is possible to try to re-write the original Eprom code??

Where might I find a copy of the original Eprom? Or would it be possible to extract the code from another Eprom I have (from an MMV modul) and write it back on the MMIV eprom?

Many thanks for your help in advance!

Hi, of course there are some different EEPROM-programmer's models, but those that support DIP-28 not easy to find - so You have to check this subject clearly before buying one. Simple data extraction and re-writting are possible also, but to change of fix something You need skills in Assembler-programming, I suppose - better ask a specialist to do this job. Anyhow it will be a good idea to use new clear EPROMs for such experiments...
