Value of 1981 HP 12C Message #1 Posted by hctablet1024 on 6 Aug 2013, 12:35 a.m. Hi, I use the HP 12C at work and own a few of them. I purchased one that starts with the serial number 21 which I understand means it was made in 1981. Would you guys agree that this means it was made in 1981? Also, what is the value of it?

(see here) For units produced between 1981 and 1989, well preserved units can be had for less than $50 USD and new old stock units (box, book, inserts, etc) is frequently available for less than $100 USD. edit: add serial number link Edited: 6 Aug 2013, 10:29 a.m.
