It's hard to guess at signals when the horizontal and vertical scales are not
stated, nor where in the circuit the signal was found.

Sony.
They wrote a book about it.
This isn't "the first CD".
The only thing this has in common with them is digital recording
on a spiral track.
Apparently the seller has never heard of WORMs or knows the history of optical
data recording.

It _is_ an SCU; see:

This sure brings back good memories!
I worked on a Sperry 1100/60 with 3 CPUs, thus an “1163”, for several years.
I was a maintainer of EXEC, MAPPER, etc, and we tested the new software
versions (fixes!) on Saturday (during the week we needed 100% up time).

In fact, I used this machine from 1988 to 1999 (the date of the

programmer on a Sperry UNIVAC 90/30, among others. This UTS 40 has a
