We can burn an 4K EPROM with the data of your choice. Because we have the TMS2532 EPROM, these are a direct replacement for the mask ROMS in computers. The normal 2732 will not work without rewiring, but the TI 2532 is designed to be a drop-in replacement.

For example, your character ROM in your Commodore 64 (part number 901225-01) has died. Ask us for a 901225-01 replacement and we'll burn an EPROM with the data from an original 901225-01 (which is freely available on the internet). To fit it simply remove the dead 901225-01 part and replace with the new EPROM.
