Tom Christiansen was a college friend of mine; that's exactly the
kind of person he is. :-)

I'm not expert on the 1401, but I understand what you're getting at.
I'm sympathetic to the view that two-digit Y2K problems exist because
of constraints of input devices, storage devices, dain-bramaged COBOL,
punched cards, and lack of code memory and processing time for
performing input validation, and the reticent nature of programmers
who didn't want to be blamed for errors resulting from updating
data or code as machines improved and data migrated.
As you said, though, you'd be surprised what ancient computers can do.
I'd hate to say something was impossible; I'll happily admit that a Y2K
problem arose because at the time it seemed the most sensible way to do it.
