As far as I remember off-hand, the VR/W is indeed the VIC-I R/W signal. The problem is that the cartridge port only carries the 6502 databus, not the part of the bus that it shares with VIC-I. I.e. during a VIC-I access the cartridge databus is separated from the video databus. -Pasi Message was sent through the cbm-hackers mailing listReceived on 2017-07-07 13:00:03
