Interesting you should mention Lab-Volt. I just picked
up one of the four
position workstations/benches along with the installed test equipment, etc.
with all the student test assemblies. It has four sets of logic trainers,
motor experiments, and radio parts along with one set of student manuals. I
didn't realize they also made a microcomputer trainer, but now I'll have to
dig around and see if I can find one :).
Our high school science labs had Lab-Volt power supplies at each
two-person workstation. Klunky looking but we never had a failure...
