They do seem rather thin on the ground. I picked mine up... 15 years
ago now and they weren't that common then. And I had a *hell* of a
time finding a 3279 - the colour version - even then.

Do we have any South American correspondents listening in? I'm sure I
read that IBM had a factory in Brazil producing these - and they kept
on churning 3278s out for some considerable time after the rest of the
world had moved on. I believe it was also stated that there was
considerable redesign using more modern components inside that classic
3278 case on these later Brazilian examples. I'd certainly like to get
hold of a couple.
