Ahhh ok. I know the square root of bugger all about Altairs; I'm
mostly a DEC pdp and IBM mainframe/midrange guy. I picked up the
Altair a few years ago as an 'oh by the way' thing when I saw it at a
cheap price; I'm only just getting into it now. It does basically
work; it seems to be running some kind of ROM because when I power it
up it runs and the lights chase like a register increment thing. But
can't do much else due to broken/flaky switches.

I'll pick up some Altair schematics and see what's called for in each
switch position.
