I have some complete BA123 supplies here. I also have 4 BA123 chassis that
are on my trailer that is heading for the scrap dealer. The ones on the
trailer have been outside for a while but you can have anything you want
from them.
I also have numerous BA23 chassis inside - just let me know what fried.

If it isn't one problem it's another. Last night I left the PDP-11/23+
(still haven't gotten it to work with a /73 CPU board) running for about 4
hours to see how it handled being left on. The only thing running was
"show mem" on the console since I was working on some other stuff.

Much to my terror/irritation, about 10pm I noticed a buzzing or sparking
sound. I quickly moved it away from the sofa, and started investigating.
It sounds as if something in the area where you've got the breaker and the
powercord plugs in is 'arcing and sparking'. I've got to take off in a
little while, but I plan on looking into this later this afternoon or
tonite.

Unfortunatly I don't have any docs on the BA123 (just the BA23), so will be
having a fun time figuring out how to get it apart.

Does this problem sound familiar to anyone, and does anyone have any
suggestions?
