Re: sick hp 5421A Digital Processor

Chris, this is dead tree format.? Unfortunately, volume 1 just had debugging instructions along with the wiring list --- no schematics to be had.
I'm betting there's a manual in the hoard from ManualsMinus, but good luck getting to that!
These boxes are truly at the cusp of a technology change.

? Indeed, I'm sorry to hear they're so hard to find over there.
? Shipping would not be cheap, but I could part with a NIM bin for a
small sum.? I'm not really trying to sell them, but I do have more of
them than I will ever need, so I'm only looking for a few bucks.? The
shipping will be the tough part.? I don't have any of the HP bins, but
Ortecs and a few others.? Ping me off-list if you'd like to discuss.
