For Switch #1:
For Switch #2 (some obscure combos not typed in)
It seems to me that one of the sacred switches will put the machine into
an endless loop of reboots - just after the self tests, etc., the machine
would boot again.
I did not know about this, and had a machine that had this "problem". A
trip to the library solved it.
You guys may be talking about Switch 1-1 -- which, for an XT, will do this.
Switch 1-2 tells it (both PC and XT) about the presence of the coprocessor.
(I do, btw, have an 8087 in my collection...only one I've ever seen! Even
rarer was the 8088 to 386 SX-16 upgrade board...the world's s-l-o-w-e-s-t
386.)
I'd like to add an 8086 motherboard to my collection...anyone have one?
