While I'm thinking about it, for any/all who might be interested, just last week, I created a step-by-step video for disassembling a UNIX PC 7300 (with a few comments/comparisons for the 3b1) https://youtu.be/vYKS-jOdcsQ I've always found them tricky to work on with the way they are packed together, so I hope this could help others who might want to take a crack at a repair/restoration (or, heaven forbid...a "part-out") -- Thanks, AJ http://MightyFrame.com http://QICreader.com http://UnixPC.blogspot.com
