So what causes the stripes? They coincide with AEC/Phi2, but that doesn't mean it causes it. I don't see anything on the chip that could cause it, so maybe it is interference on the board? > What I do notice are the grey dots of the HMOS-II VICs. That seems to be caused by the different boards, not the different VIC revision: the #CS signal is too early (relative to the data bus), which means that when you write a colour reg, it first gets written with all ones, getting the correct colour only later that same cycle. Delaying the #CS signal (adding a cap is enough) gets rid of the dots. Segher Message was sent through the cbm-hackers mailing listReceived on 2011-11-17 22:00:04
