23128 Adapter


This is a adapter that converts the 27C512 EPROM so that it can be used as a 23128 which is used in retro computers like the Commodore and Atari.

A14 and A15 are pulled high so you will need to program the 27C512 from location 0xC000 to 0xFFFF

On the bottom side of the PCB there are jumpers JP1, JP2 and JP3. This is already configured and does not need to be changed. Only one jumper needs to be shorted and is for future use.

The adapter has gold plated pins which for better electrical connectivity.

Make sure you insert the 27C512 (Not included) with the correct orientation. Take note of the notch at the top.
