Yeah. I've heard about that. Look at it wrong and pzzt! My simulator was much cheaper (free) and nothing to fail.

From what I've seen most of these old Woodstock's have often been repaired in one way or another. A new (board to replace the ACT) CPU, batteries, power supply etc.

For my "experiment" I'd use a PSU with a current limit (set low) just in case.

PS: I just reread the "manual" and my 29C "simulator" is actually an emulator (of original HP microcode). Even better!
