On: Ask HN: What is the oldest computer that you still use for production?

TRS-80 Model 100 laptop (with an RS-232 connection) for our security panel.

I might as well claim my trophy now. Where is it?

Edit: We also have several SPARC Classics running some pre-2.5.1 version that are doing phone switch stuff.

The model 100 was in a class of its own. Crazy battery life, a day of continuous use on a bunch of penlights.

Oh, and here is your trophy ;) :
