But on the other hand, the VIC-20 has some buffer chips on the bus that the C64 doesn't have. But why don't you use a normal 2764 or 27128 EPROM? The pinout is not that much different. BTW, does anyone know where one could buy nicely built 2764->2364 adapter sockets? Marko - This message was sent through the cbm-hackers mailing list.
