This may not apply, but thing you may want to check is the speed designation of each chip: 6545 = 1 MHz = 6845 ---- = 1.5 MHz = 68A45 6545A = 2 MHz = 68B45 6545B = 3 MHz = ---- So if you were putting a 6845 in a system that had a 6545A, there will be a speed problem. - D <david@atari-central.com> http://www.atari-central.com - This message was sent through the cbm-hackers mailing list.
