Doh!! It's been a LLOONNGGG time since I had this Apollo out and running,
and of course I had forgotten how these things work... Of course, the "ex"
command is part of what I forgot... And to make things a bit more
interesting, I also forgot the root password. But luckily my memory came
back quickly, I'd hate to think how long it would take to get it back up
running if I forgot the password...

My favorite part... It's the only one that has every worked very well for
me. BTW, when in service mode don't forget to hit the return key to tell it
that you're there...

actually you should type "init", at least on my system.

I've noticed that. Also a lot of errors if you run DEX and it's not hooked up.

Ouch!! That wasn't very nice... But I don't think it's from a 5500. Maybe a
4000 or a 3000, but not a 5500. The machine seems to recognize it just
fine, but won't do anything because it doesn't have the SAU7 stuff loaded.
So now my DN3500 is loaded down and ready to pop circuit breakers(as if
that huge monitor couldn't do it alone). It's got 32MB RAM, a WD-7000 disk
controller(got two more of those and lots of OMNI's), an ugly little DR
network card(maybe I'll put ethernet in) and the PC card. No floppy drive
or tape drive, gotta work on that later. But first I need to figure out how
to hook up and access two drives atthe same time! Can't boot from a disk
with no OS, but can't plug in two drives at the same time with the cables I
have...
So next I'm going to try to stuff one of those 3000 motherboards(or was it
from a 3010?) into the old 3500 case and see if I can't get it running.
Unfortunately, I only have one keyboard and one monitor. But I DO have TWO
mice. The new one has three buttons that are kinda slanted, and on the
bottom it says it was made in Switzerland. And it's backwards! Roll it
down, the cursor moves up... Might be good for an upside-down trackball
though ;-)
