I have this cool DEC "Computer Lab". It's a box with a power supply,
some switches and lights, some logic, and a variable clock. Here's a picture of
the thing:
You use jumper wires of various lengths to connect together the circuit
you want to build. There is a workbook (and a teacher's edition) of exercises
that turn it into a course on computer logic. Here are some pictures of the
wires (I think these were taken by Ashley of his wires):
There's an intermittent that is cured by flexing the box a
little -- perhaps a bad solder joint or the like. But other than
that, it works great.
In case you were wondering, it does indeed use the same switches
as the PDP-8/I :-).
