Looking again: Scandoubler/Flicker fixer for a 1200

[Starrunner]

Every time I think I got or are given a solution, it disappears. The latest was a little thing from Amigakit that they appear to be sold out of now.

So once again, I need help getting off my old 1084S. Any suggestions or items for sale would be greatly appreciated. I will not do eBay.

Thanks as always
