Please forgive the delayed response--for some reason, the CCTalk server
belched up a bunch of messages dating from 30 November onward today.

I've read a bit on the HPMuseum forums that indicate that early displays
aren't interchangeable with later ones--the later ones apparently use a
finer-pitch connector.

My own HP 16C has a serial number beginning with 2228A..., which I
believe puts its date of manufacture in 1982, so my fingers are crossed
to see if the "old" HP12C that I picked up on eBay is even close in
terms of display connections.
