… here’s a new one on me.

Notice anything strange?
A good close look at the envelope generators on the left maybe?
The jacks are backwards!
Anyone ever seen this before? (I haven’t)
This is a Moog 55A that was built in 1982.
Pretty late for most of their modular sales.
Perhaps they used reject panels? Tried different layouts?
Seeing an RA Moog module in a 55 is commonplace, but what’s with the 911 jacks swapped?
Those holes are punched at different diameters, so it was no accident.
Another weirdy: the 930 PSU is only half anodized.
The bottom is bare metal, but the cage is black.
By 1982 maybe they were running out of parts?
Here’s the whole thing below.
Lots of blank panels, but more than enough to be interesting.
