I didn't realize any problems with that PLA. The PCB must be the same as that in the downloaded Gerber files. You have to use the .bin file in the following link: http://www.zimmers.net/anonftp/pub/cbm/firmware/computers/c64/ Scroll down and download the 251064-01.bin file. Try this one, otherwise try the next file. I programmed the OTP Eprom with the TLL866 programmer, using the PLCC adapter and a normal (in my case) ST M27C512 PLCC Chip.
Good evening, I have downloaded the file you suggested but it still does not work. what am I doing wrong or am I forgetting something? Is the dil 28 socket only for in the motherboard or is it for making an adapter? I have also programmed with a TL866 eprommer only my OTP is a Winbond W27C512-45Z can that make a difference? I do have pictures that show what it looks like now, but then I have to place a new comment. Best regards,
Yep, it's space saving and looks much more better !
