Repairing the Commodore 1581 floppy disk drive. Part 2

I assumed that the Commodore 1581 was failing because of a bad WD1772 IC (as documented in Part I). So I ordered a WD1772 replacement + the IC socket, I developed some basic desoldering skills, watched some desoldering videos, and also got a cheap desoldering iron from Radio Shack: So, I removed the board from theContinue reading “Repairing the Commodore 1581 floppy disk drive.

If so, it mustContinue reading “The quest for the sacred diskettes”

And Jeri Ellsworth was there too. I went with my Commodore mug andContinue reading “Growing the 8 Bit Generation”
