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)

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")
