PDP-11/04 Console Repair - Part 1

Good job on this! I can't express how useful it is to see someone posting a video that goes through their entire debugging/repair process. Your block diagram is also incredibly handy. Thanks!
 
Thank-you. I'm glad you found it interesting.
Viewers of repair videos on YouTube seem to enjoy watching the fault-finding process, even though it makes the video longer.
(but leaving most of the confused head scratching while testing things, until a discovery is made, and then trying to come up with ideas on how best to proceed)
I hope the block diagram is of use to owners of M7859's. I'm fairly sure it's without errors, but if any are found, or if something is unclear, I'm happy to hear about it and help out.

Stuart^^^^ I can't reply to your PM!
(Sorry to others for this bump)

Though part of the PM is about the "exerciser" system I've developed for the M7859, and referenced in this thread.
I've had a couple of requests for this, and plan to make it all available in the not too distant future.
