Sure thing. I have one of those beasties. Before I could afford a
good oscilloscope it seemed like a nice way to bench-test some digital
(DTL & TTL) circuits. Modified mine with connector for the cable
attachment to the box so I could plug in different IC clips for different
sized components. Also could use it as a pretty dumb "logic analyzer"
with a cable that had clips or probes on each pin.
It never worked very well for dynamic circuits (not surprising) but I
did get a lot of use from it while breadboarding.

I found an
interesting gadget at a hamfest last weekend. It's a Digi-Viewer
made by SwTPc. It's a gold colored metal box about 6 x 5 x 4 inches. It
has the outline of an IC on it and 16 lights around the outline to
represent each IC pin. There's a cable coming out of the box with a 16 pin
chip clip on the other end. It's AC powered and looks like it uses
incandescent bulbs instead of LEDs. I've never heard of one before but it
looks like a prehistoric IC pin status display. Anyone here ever use one of
these?
Yes, I have seen them, but that's about it. SWTPC made quite a few things
that were not related to thier 680x based micros - in fact some things
were not digital at all!
