EEPROM on A1200?

[ameegah]

Do you mean EPROM or EEPROM?   If you mean EPROMs like the 27C400, there's some guides in this thread on how to do it here with a cheap willem eprom programmer:

Can usually find 27C400 eproms on ebay like here:

No problem, but don't thank me :-) Thanks to Amethyst the person who wrote the guide.  I followed those instructions and it worked perfect for me.  Only extra things that you may need are an UV EPROM eraser to erase used chips and an antistatic wrist band so you don't damage chip from static.

Yep, if you read through the thread from english amiga board forum link, it says earlier on in the thread that the unused space should be filled "just to be safe" so no surprises that it works fine when you leave it out.

Something to do with the 27c400 having an extra address pin and the possibility of it being left "floating".
