There are two units now listed on the "evil empire", but it is not clear what is
in them. At least I cannot fathom it.

Hah.. nobody can.  There's theoretically a sticker on the 5087A that tells you what modules are in it, but every one I've seen has had modules that are different than the sticker, and some sort of cryptic pencil scrawl on a piece of tape, or the back of the box or the front panel telling what modules are where.  And it's inevitably wrong.

There's slots for three input modules (A,B,C), and 10 output modules (1-10), and they're all optional and easily reconfigurable.

Everytime, I wind up taking the cover off and actually looking at what's in there.
