I have a spare HP 141T Display Section that I acquired as a source of spare parts for my Spectrum Analyser. It's heavy to keep in my loft for storage, so I decided to dismantle it.

I have repaired a lot of HP equipment and usually start by dismantling to assembly level to clean everything up and inspect for any obvious problems. Normally an easy process, just take lots of photos and notes, occasionally have to desolder a wire or two, then reassembly.

Not so with the 141T, this must have been a nightmare to manufacture! Complicated wiring looms and lots of individual pin contacts to the pcb's. Must have been a design throwback to valve (vacuum tube) technology and metal chassis. Cableforms pass through holes in metal panels, so impossible to remove. Some parts riveted on instead of screwed. Usual problem of connectors on front of panel with wiring behind, so again can't be removed. I don't want to cut the cableforms, so maybe will cut the panels instead. Anybody know if the contacts can be removed from the special D-type connectors?

I will post the spare parts on my website when finished this complicated little project.
