Hi,
I have 2 that may be suitable.
1st is a atari stereo single scan monitor (14 inch I think), model SC1435? Its a 9 pin connection on the back, and stereo phono input. I basically made a lead up using a cheap scart switch box to use it as a monitor/tv, but would be easy enough to make up a standard lead if needed.
2nd is a Commodore 1942. Fully working, a few marks here and there and one of the hinges has broken on the front flap. It does suffer from slightly flickering brightness occasionally (tends to be when in overscan mode), but believe its down to a worn brightness control on the front. Its got its original box & manual, and I have a copy of the driver cd floating around too.
To be honest I've not much use for them anymore, as I tend to use my TFT tv scart input if I want to use old screen modes or equipment.

I'm in the UK, south wales not too far off the M4. Delivery will be fairly costly as they are heavy, but you can have either (or both) for a small contribution - or do you have anything you don't need you wanna swap for?
PM me if interested. :-D
