came across an interesting part. It was a Delay Line, part number
ADL-CN037. I forgot who the manufacturer was, but it was someone big
and established (GE maybe)?
Anyone know what this is?
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.
