I have a couple of these lab panels (H901).
Here's a couple of pictures of one:
These are pretty cool, and apparently were used to build the first
prototype of a PDP-8/S. You insert flip-chips in the back, then wire them
up with patch-cords on the front. There are logic diagrams on the datasheets
for the flip-chips (I should scan mine, someday), which fit in the gaps on
the front to remind you which pins do what on that flip-chip.
Their main drawback is that the sockets are single-sided.
That means they work with most of the older Rxxx, Sxxx, Wxxx modules, but only a
small minority of the newer Mxxx.
I'd love to get ahold of some of the "911" patch-cords for these.
