Also on OSH Park is an adapter board to use the clone CIC with Nintendo's CIC socket, it would work nicely with this LoROM board.

Hi all,
I'm X-death ( bastien) the creator of the PCB ^^

i can share gerber if you want to use other pcb maker.


Hey, X-death! :D

The gerber files can actually be downloaded from OSH Park. But if you used Eagle, it would be fantastic if you could share the schematic and board files!

No, that's an OTP EPROM.


Aye, and they're about $10 each! EPROMs are much easier to prototype with, but being OTP defeats that purpose. So that being the case, I'm not sure why I would go with a OTP EPROM when a flash chip is less than half the price. But I can understand why people would want to use old EPROMs. They're MUCH easier to remove for reprogramming if need be.

Hey X-death,

It's almost one year since you said you would share your gerber with us, do you still have the schematics and gerber of that pcb?

Hi all,

Have anyone designed any functional snes pcb that uses a 27c322?

I'm sure that retrostage.net had boards that used 27C322 chips, can't find them on the site anymore..
