Is it possible to replace a 64mbit toshiba prom with 2x 27C322 eproms? Do they even have the same pinout? (TC5364205AP)
I saw a post somewhere about combining 2x 27C322 to replace a broken/bad 64mbit toshiba prom in a mvs cart.
How to connect them 2 eproms to get them to act like a 64mbit prom? Just piggyback and lift some pins pins?
I found this picture, from another forumpost.
"If the PCB decodes the ROM with /CE, attach your decode circuit to /CE, if it uses /OE attach circuit to /OE."
Could anyone shed some light on this please?
I have a RBFF2 that gives me constant jailbars
