Afraid so. The IBM 360's used the 1052 typewriter for a system console. The
ce's loved them. When an internal drive belt broke, they had to disassemble
half the typewriter to install a new belt. So they always looped a couple of
extra belts around the main drive shaft for future use. Unless you had an
alternate console, the whole system was down while they worked on it.

Not quite. 1898 was my grandfathers DOB. Though there are days I sure feel
like it is. I'm actually on the leading edge of the baby boomers, 1945. I
guess more Cretaceous than Jurassic. I

The first consoles I used were ASR-33 Teletypes. IIRC they also had a built in
acoustic coupler to an internal modem with a baud rate of 110.

I'm near the other edge, 1950. It makes working out my age easy :)

I recall seeing a "tape" with 1 hole width. I still haven't actually
fully realized, how it should work, since I recall wondering that the
holes didn't seem to differ from each other.

How would you know that? I might have some weird fetish :P.

Mentioning my age was a pun for Stephen. I've *never* seen such card nor
tape in action.

My naive guess would be that they're tensioning the tape by winding it until
a soft tab slips out of a slot at the right tension.
I don't remember reel-to-reel tape streamers chattering. Of course, the only
ones I used were in a big room full of mainframe where it was hard to hear
normal speech, let alone machine noises.

The NFL should go international. I'd pay to
see the Detroit Lions vs the Roman Catholics.

You would have enjoyed the the IBM 2560 MFCM (Multi-Function Card Machine). Card
reader and punch with two input hoppers, 5 output hoppers all selectable under
program control. The IBM engineers had a somewhat different interpretation of
the its acronym. I can leave that to your imagination.

I once used a portable terminal with an acoustic coupler to dial into work from
home. I can't recall if it was 110 or 300 baud. At the time I was quite
impressed. Now I can't imagine how I ever got anything done.

Well who came up with the acronym AMD (Air Movement Device) for a fan? :-)
