I am looking for a data sheet (or at least a pinout)
for an IC
numbered PIC900C. Despite the number, this is not a microcontroller,
it's some kind of power driver IC -- from the 'house code' on it, I
suspect it's little more than a transistor array, here [1] configured
as a full-H driver foo a motor. FWIW it's in a 'wide' 18 pin DIL
package with a metal top surface to attach to a heatsink.
Here's an old Unitrode app note showing a circuit using the PIC900B
with a UC3717 chopper driver, that includes pinout of said PIC900.

I realize it's on the Web and not in a databook and that it might
requires something developed within the last 20 years to access it,
rather than an HP9830 and an oil lamp, but here you go.
