The first time-base corrector I ran across was in one of the
early model quadruplex video tape units (probably Ampex VR-1000
or VR-1200)

The TBC was implemented as an L-C delay line, with the C's being
voltage variable capacitors.

No, it didn't store an entire frame; maybe not even a whole line,
I don't remember.

Isn't history wonderful?
