Probably just a "standard" mercury
delay line. The RL11 I've got
behind me uses one for its write precompenstation, and there are
usually lots of them in "older" video equipment (like 70's or early
80's). They do what they sound like, add a delay to a signal, usually
on the order tens of microseconds for stuff I've seen.
Some early machines used large versions as their primary storage, they
functioned somewhat like a (more) solid-state drum memory.
Exactly. So what I should have asked (what I meant to ask) is does
anyone have any data on this part to determine how long the delay is?
I'm thinking it would be neat to try to use this (or a number of these
in series) to create a delay line memory to experiment with.
