Joe,
The RQM Systems Power-Start boot loader board has 16 'load address' switches
(set to C000h), 8 'sense' switches, and 8 each called 'IN 376', 'IN 375',
and 'IN 374' (obviously octal representation). There is a 'Board Enable'
paddle switch on the right, tons of basic TTL and a 74S472 PROM (512x8 bits)
with room for one more.
Probably loads the disk controller start code...

As for your question below Sellam, I'll give you 3 guesses and the first 2
don't count.
P.S. I'm unemployed.
