8pcs 27C322 to SNES Rom adapter

This listing is for a total of eight (8pcs) adapters, a pre-scored pcb of 2x4 boards.   

To avoid shorting, these new boards have exposed pads on the bottom, put tape on these if your donor board have any exposed pads

What is it?

This listing is for one adapter board that takes 27C322 and makes it compatible with standard 36pin SNES ROM pinout. Works fine with both LoROM and HiRom games on both my game pcbs and the originals.

Stuff you need

Snes cartridge PCB with space for a 36pin rom (My own works best, of course!) On some boards a few components needs to be moved, the adapter is as small as it can be

• 1x Preprogrammed 27c322 chip, 27c160 chips are supported, see page 7 of documentation
• 2x 74 257 SOIC
• 2x 18 single row header pins

Patience when assembling, its tricky, the total clearance inside a standard snes cartridge shell is only 6mm!

The assembly is difficult, please read the instructions!
