robbo007 Posted May 8 Share Posted May 8 Hi, Is it possible to source eeproms 28pin that will work with the Mega 4 ST 2 ROM version? I've got a ROM burner but not sure what eerpoms are needed? I've got a German version of TOS 1.02 currently. Regards, Quote Link to comment Share on other sites More sharing options...
snarkdluG Posted May 8 Share Posted May 8 (edited) There is no eprom that is 28pin and compatible for 2 rom. Either you need an adapter for 32pin eprom or use 6 roms (28pins). Or get original maskrom of TOS v1.04 that is 28pin. Edited May 8 by snarkdluG Quote Link to comment Share on other sites More sharing options...

Tillek Posted May 9 Share Posted May 9 Actually a couple threads down I posted an alternative. Check the TOS 2.06 threads (though it didn't really apply to TOS 2.06). I've used these in my 2 chip Mega's Quote Link to comment Share on other sites More sharing options...
