Ugh I brain-typoed; of course I meant "2400 - the default"!

And one of the first thing I did was check for traces going to pins on
the WCS console connector; that's why I'm confident my wiring is OK.

But I will recheck switches.

I haven't got into scoping the 8085 yet; this is really a quick and
dirty sanity check: does it get the ROM> prompt? Yes... great - move
on. Status known. No... check obvious finger trouble... still dead?
Not good but status known... move on.
