Hi. >My SX motherboard (PNO 251102 REV A) has a 28 pin socket for the >kernal ROM, which is a 2654 EPROM. The schematics lists UD3 as being >either a 2364 or a 2564. Can I plug in a 2364 ROM in the socket >without modification? Is there a jumper or something that I need to >change? I'm asking because I can't seem to find the correct pinout for >the 2364. The only one that I've found (in Marko/Pekka's 256kB memory >expansion project) is obviously incorrect as it only lists 12 address >lines. What about the schematic in the C64 ref guide, also can be found on funet. 2364 is a masked ROM and has 13 addr lines of course. And I remember exactly in past I replaced it with 2764 28-pin one, but some wiring has been made around it. Frank - This message was sent through the cbm-hackers mailing list.
