An excellent trip down memory lane. I no longer have the memory and
cognitive skills I once had but there are events in my life I still
remember and cherish. The first computer I remember working on was the
either the PDP-7 or 8(classmates at that time no longer live here in rural
Ontario to consult with) at my high-school where the electronics/electrical
teacher had in his office. It was a donation from a wealthy benefactor, an
alumni, who saw the future and said computers would revolutionize society!

I want to thank you all for this IBM 360 conversation.
It makes me feel
young🙂. My first computer was a PDP-8/L with 4K of core memory and a
Teletype ASR-33. That was 1972 (I was 12).

of that era. The ones I remember from our 360/44 had capstans that turned
continuously, one to each side of the head. The tape was shoved against
the capstan to start tape motion, and against a rubber brake block to stop
it. That was wild enough, but the other crazy aspect is that the vacuum
columns were arranged so the oxide was facing outward, i.e., rubbing
against the side walls of the vacuum column.

I think the 360/67 replaced "Halt and Catch Fire" with "Rewind and
Break Tape."
I always wondered if that wasn't a standard property of IBM tape drives
I never did wear out a tape, but then again, I never used a tape more
than a half dozen times on that system.
