Hi all,
Bought an XT on eBay but a 5150 arrived instead (I guess the seller didn't know it was a 5150, the picture was blurry).
Sold as spares or repairs.
When I powered it on at work it threw garbage up on the screen ( I didn't have any disks with me, I wasn't expecting it to arrive until tomorrow at the earliest)
It booted fine with a DOS disk in it when I turned it on at home a few hours later.
I decided to investigation what the cause of the garbage was as it was supposedly stored in a shed for many decades. I removed a few DIP rams which had filthy contacts and small amounts of corrosion. To cut a long story short does anyone know where I can get a replacement MOSTEK 8225 (MK4116N-3GP) as one of the contacts simply fell off. As well as that does anyone know if dirty contacts will have caused that stuff to appear on the screen in the first place?
