Hi,
Re: the timing fix,
E123C, E125C are on the underside of the A1200 motherboard near the Alice chip (U2)
I have a Rev2B A1200 and Apollo 1240, I did not do all of the rev 2B mod, I removed R118 and did not replace it and left off the 470 Ohm pull up, all worked fine!
removal of E123/E125 correct a timind delay of about 8 Ns on the 7MHz and CDAC signals, which link to Budgie (system clock/ram controller)
Note sure about what the ALICE timing and video tearing fault is. It could in part be to do with the general motherboard mod. I think there were different filter components on some amiga motherboards for the video.
Hope this helps,
Ian
