Hello! I am building a ROM replacement for the C64, and I am finalizing the PCB layout. The PCB will be plugged into the sockets for all three ROMs (CHAR, KERNAL and BASIC), so I need to know the exact spacing between these ROM chips. I have the ASSY 250425 (old) board, with three DIL24 sockets. I measured that they are spaced 0.2" apart. Then I have the ASSY 250469 (new) board, with one DIL24 and one DIL28 chips. They are also spaced 0.2" apart. Unfortunately I have no other boards. From what I saw in various photos found in Google, all the other boards should also follow one of these two ROM layouts and spacing, but I am not sure. And I have no idea about the SX-64. Any help would be appreciated. Regards, Michau. Message was sent through the cbm-hackers mailing listReceived on 2013-05-02 12:00:03
