This is likely elementary but many times I run across the encased laptop
and other function(eg cordless drills) batteries. Of course each has it's own proprietory
charger which have long since disappeared and are costly to replace as well as being
device and company specific . Many of them have a 3rd terminal. What was it's
purpose.
Can you recharge these batteries simply by rigging up an interface using appropriate
voltages and polarity ? How would you deal with the 3rd terminal ?

Any good sites for the CDC box's. I guess they are repackaged SGI?

Wrong definition, I suspect :-) Especially if you ask my wife! Probably
even more so if you ask some of my work colleagues about my collection.

It would be more accurate to say they're LIKE PS/2 keyboard cables, except
they need a male (6-pin miniDIN) connector both ends, AND they need all 6
pins wired up. PS/2 only uses 4 wires (pins 2 and 6 are unused), and so PC
6-pin miniDIN cables are not fully wired. Mac cables probably are.

I was going to say that Indigos boot fine without a keyboard, using the
first serial port as console -- but in fact you have to change the PROM
settings (setenv console d, or setenv nogfxkbd 1) to do that, for which you
(initially) need a keyboard and monitor :-(

I won't relate my EDS horror stories (same song, second verse...),
but Ross Perot left in 1984-85, long before the presidential run.

Curious. The 520 we had was more like a large deskside system. No video,
though
probably one was offered. Definately no built in monitor. We used the
standard HP terminals as consoles. I never saw it referenced as a 9020.
we also had a 540, but I don't know what the differences were.
But they were really cool UNIX boxes. You could hear your data on the 404Mb
drive being read and written. And they were built like tanks.

I am looking for an online reference to help me calculate how
much live load (AKA VAXen) I can put on my living room floor.
The floor: 2x10's 2 foot on center, approximately 14 foot
span (guess, too lazy to measure just yet). 3/4" OSB on top,
carpet, 1/2" OSB (to keep the VAX from squishing into the
carpet)...
The VAX: 1100 lbs of true blue & white BIG IRON! minus
whatever I remove for hand transport.
Me: 300 lbs of Coca-Cola and Hostess fruit pies :)

PS I also want to replace a smallish steel IBeam with
a micro-lam, so steel numbers would help too...
