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...

David,
I looked at your auction. What is this > "one RQM Systems Power-Start
boot loader board w/ 48 DIP switches"? I had two Altairs and one had the
MITs autostart board. It was a standard MITs EPROM board with one
pre-programmed 1702 in it that contained the same code that you normally
had to toogle in by hand. IIRC the code was only 48 bytes or some such. No
DIP switches on it though.
Joe
As for your question below Sellam, I'll give you 3 guesses and the first 2
don't count.
P.S. I'm unemployed.

Hi David.
Why on Earth would you be selling your "pride and joy"?
