Oldest computer you've used for "real work"?

Probably not that impressive an age compared to some, but what I find amazing is that there's still no better tool for working in hex/binary/decimal and flipping between word sizes and complement modes.

Agreed. I sold mine, also purchased from Educalc, only because someone was willing to pay a hideous amount for mine. Four or five times what I paid, maybe more. I don't recall its original sales price.

I soon regretted it because as you said there really is no substitute, until learning (here) about the amazing WP-34s. It's overkill for the task, but nothing else comes close to emulating a proper 16C. The WP-35s does it perfectly. Better, in fact.

There is also the SwissMicros DM-16, which I do not have. From what others have said, I probably won't.
