Just received the motherboard today from ebay now tested the motherboard.
It boot the floppy drive fine,
but NO display form RGB port or TV RF port
then I have tapped the board but nothing
but then I tapped the simm module and RGB and RF display a picture on the screen it will not stop going backwards and forward left to right on the screen
I have look at the motherboard and somebody has done some soldering near to the RGB port there is a silver Square can that can be adjusted is this anything to do with the screen backwards and forward left to right.
My 1st job I will do is resolder the joints to do with the simm module maybe a dry joint.
Can anyone help me identify the board and model and I do not know if this is a 1MB version or 4Mb?
so any help is appreciated on trying to get this board back up and running
