 ULN2003A is, according to my Sprague handbook, a 7-channel 50 V, 500 mA output
 Darlington driver.  Pins 1-7 are the inputs, 16-10 the corresponding outputs,
 7 is ground, and 9 is a common - each output has a diode "pointing toward"
 common.  No doubt nice for bypassing kickback from inductive loads.

 The 1402 may be an RCA CMOS micro.  (?)
