The easiest thing would be to find a SpectraTAC receiver chassis somewhere
and drop your receiver into it.
Lacking that, you only need to provide 12V and 9.6V to a few pins on the
board to light up the receiver strip. See the schematic for the receiver or
the Micor system board to get the pinout - it's straightforward. From
memory (so don't hold this as gospel, check the docs), you have to provide
12V to one pin, 9.6V to two pins, ground, ground the F1 channel select line,
that's about it. You won't have squelch or volume control, but you can
monitor the discriminator audio output using an outboard audio amp (a cheap
amplified PC speaker makes a handy audio amplifier for the bench). An
LM7810 10V regulator with a series diode on the output will give you 9.6V if
you don't have a variable output bench supply (I believe Motorola's spec is
between 9.3 and 9.9V if I remember right).

Scrap the chassis and get another. Or, if you were successful in finding a
SpectraTAC chassis, use that instead....
