I'm starting to play with my new eprom programmer (an MCUmall GQ-4X) and want
to make some new kernal roms and other roms for some of my machines ;-)
At last night's TPUG meeting there was mention of the ROMS in the original
C64... well, they are 24-pin "2364"-type roms. Normally to burn a replacement
ROM you would use a 2764 EPROM, which is a 28-pin chip, and you would need an
adapter. But, you can also use a motorola 68764 eprom which is a direct
replacement 24-pin chip.
Unfortunately it seems my new burner doesn't (yet) support that chip, so I will
need an adapter.
Also, the person at the meeting with the EPROM adapter
boards from ebay, would you have an item# or storename of where you got them?
I looked and can't find anything. I also googled for non-ebay sources without
luck...
And lastly, does anyone know of a good place to get blank eproms? 2764 or 27128.
Thanks,
Steve
