Default Re: Modeline problem

Progress - at last!

I managed to get WinXP Pro to run (had to use a PS/2 keyboard!) and am now getting correct video and syncs so I guess it must have been an OS problem.

Connected to the TV22 video amp grid and I am now getting a picture of sorts. Frame trying to lock but at the end of the control so I guess I need to tweak an R or C in the oscillator due to my transformer rewind. Also got a brighter vertical in the centre of the screen which I think means I need to adjust the sync drive C28.

Lots to do but I'm delighted to have got going again after a frustrating couple of days. I'll post a picture shortly. Thank you so much for your help.
