motor start capacitor

When I started out we used switches, one per bit.

How fast could you re-enter the boot code into a PDP-11? :)

That depends on how big your boots were. :) I made sure a lot of them would never boot again, and sold the leftovers. They were from leased CAD systems that were being retired, and had to go through certified destruction, but were were allowed to sell lots of the parts. I still have a pair of aluminum racks from the LSI versions that were used to process CATV bills.

Yeah, but you had 0's and 1's to work with. When I started out we only had the 0's.

AND - we had to whittle our own chips.

Take care.

REAL programmers keep getting confused between Halloween & Christmas (Oct 31 = Dec 25).

Well, I got the capacitor from Grainger and the door opener works flawlessly now. So I've no idea whether the original failure was a freak coincidence or not :-)

I hadn't realized that Grainger only sells to businesses/institutions, but the guy there helped me out by pointing out that my employer (U of Maryland) has an account, so I was able to buy it. Woohoo.
