Which HP12 to buy?

[Jake Schwartz]

I can confirm the Fall 1981 intro from another angle - Richard Nelson, Jim DeArras and I were flown to Corvallis a week before the 1981 PPC Calculator Conference, which was held on August 22nd. We spent the week beta-testing the 75C (which was still a year off) and a handful of HP-IL stuff (only a few months off) but while we were there, we ran into a guy (whose name I don't remember) who showed us the 11C and 12C prior to their announcement. We didn't even get to hold them in our hands, but he let us look at them....he was afraid that he'd get into trouble :-)
