Hey, I've got one of those somewhere (the delay line, not the terminal ;-)
)!
I do still use the cabinet as a desk, as well as a few parts here and
there; to think that today something like an Arduino nano can replace that
desk-sized cabinet containing a substantial power supply and a card cage
with at least a dozen cards IIRC... I'm still amazed by how far we've come
in less than my lifetime...

I know that the CRT display controller on the CDC 200 series terminal
(INTERCOM, Export/Import 200 software) used a 10 msec magnetostrictive
delay line.for image storage. Glass would seem to be a more
mechanically robust storage medium.

Later raster terminals used MOS shift register memory.
The STAR-100 stations used a track on the station microdrum for video
refresh.

Wasn't some of this glass delay line memory used in early raster-scanned
computer video displays?
I don't know about that one, but a delay line is a key component of a
