1. I acquired an Ultra 10 without a power supply.
An online doc at Sun gave a pin-out that matches
a power supply I have from an Intel tower.

But the Sun doc said to measure the voltages with
the power supply plugged in. That would make the
pin-out backwards (unless it is an "xray view" from
the other side of the mother board).

This power supply is labeled "SH-250ATX High Quality
Switching Power Supply"

Should I risk plugging it in?

There's no risk involved as the Ultra 10 uses a standard PeeCee ATX
power supply.

Well, I hooked it up, and plugged in a PC monitor to the VGA port.
I can hear the sounds of booting up, but nothing on the monitor.
(I used to use Sun a lot at work, so it sounded like I remember.)

It has a card with a connector for one of those really cool big
Sun monitors, which I don't have.

Do I need to change a jumper or remove that video card to use
the VGA? Or is it likely the VGA circuits are damaged?

After the christening of his baby brother in church, Jason sobbed
all the way home in the back seat of the car. His father asked him
three times what was wrong. Finally, the boy replied, "That preacher
said he wanted us brought up in a Christian home, and I wanted to
stay with you guys."

You need a Sun keyboard, otherwise it will use serial port A as the
console.

It should default to the VGA port if you pull the 13W3 frame buffer -
but you'll also need a Sun keyboard as Thomas said, otherwise it will go
to serial. With no frame buffer or keyboard, the VGA monitor should at
least display a message saying it has gone to serial.

I didn't see a message from a Thomas. Serial, huh?
I bet I can scrounge up something....

(Still have a smart terminal I built thirty years ago,
but I'm sure I could program one of my other machines
to play console to the Sun.)

I guess I need to seriously try to find my way around the Sun docs
online. Lot of stuff there, but kind of hard to navigate.

I've noticed lately that the paranoid fear of computers becoming
intelligent and taking over the world has almost entirely disappeared
from the common culture. Near as I can tell, this coincides with
the release of MS-DOS.

I think it will if my H19 (VT-50 emulator)
doesn't work. Thanks.
