Today I picked up some modules marked with the Square D logo and the name NorPak on them
along with Class 8853 and Type TO-7. The modules are about 2 1/2" square and about
2" high and have two symbols of Op_Amps on them along with three ten contact terminal
strips. The terminals have holes for some kind of small pins to plug into them. Next to
the Op-Amp symbols they're marked "250 Ma DC Amplifier (2)". They look like
plug-in modules for some kind of electronic training device. Is anyone familar with
these?? Google didn't turn up anything.
