Finally got the lock off my 250, and hooked up my Xterm. Using correct
null modem cable, I still get no display at all. Obvious conclusion: the
term is toast.
So, does anyone have a spare gxt-100, -150, or microchannel version of
either? I'm so tired of having to use this Winblows box, and am getting
desperate.

What kind of terminal is it that you have? I wasn't aware that you
could attach an X-terminal to the serial port.
If your Windows machine is close enough to the RS6K, attach the serial
cable from S1 (make sure you're using S1) to a free serial port on the
PC and test it out with some terminal program. I recall having a deuce
of a time getting it to work with Hyperterminal, but I also had
tremendous troubles with using a cable that I *thought* was the right
kind. Even with the right cable it can be a nightmare of making
certain all the settings are correct:
9600, n-8-1, flow control: cts & rts, no xon/xoff
are my settings in TE/2 on OS/2.
It's imperative that you set the speed to 9600, not "highest possible"
or whatever. You can reset this (in SMIT IIRC), but it almost
certainly will only talk to a terminal or terminal emulator at 9600
baud.
And no, I don't have a spare graphics adapter. The one I have is the
only one I've got.
Sorry if this info is too basic. Hope it helps.

It's a Sun River terminal, has a 9-pin female connector on the back marked
host. A friend used it for awhile on a SparcStation 5, to run Xwindows.
That was a few years ago, though, and neither one of us had any use for it
until I got the key out of my 250. Still, for a buck, I guess I can't
complain :)
BTW: I have managed to get it running through a term emulator on the PC,
so the cable is good. Problem is, the Winblows box is for the wife. Kinda
hard for both of us to use it at the same time...

Is it this: http://www.firstsol.com/adds/anetterm.html ?
Looks like it needs to connect to the host over ethernet, but that
other terminals can connect to *it* (acting as a terminal server) with
the serial port.
(Actually, that's a text terminal, but my suspicion would be that an
X-terminal would be even more likely to behave that way)
So don't throw it away. If you can use the Windows machine long enough
to get the RS/6000 configured, the terminal may work out for you.

No, it's a SunRiver model ST-VGA...had to go dig it back out of the closet.
Searching on the web, the only thing I could come up with was this:
http://www.iasonline.com/scounix.html
It's about installing IAS under SCO, but appears to indicate that it is
indeed a serial terminal.
Any other thoughts? I'm going to recheck my cabling, as both the 250 and
the PC have 25-pin serial ports. Perhaps the 25-9 adapter I'm using has a
crossover in it somewhere.

Even if I can't get X running on it, I should be able to use it in text
mode at least, wouldn't you think?

Curious: how did you remove the lock from the 250? Does anyone know;
without the lock mechanism is it set to "normal", "service" or
"secure"?
Regardless of how the key is set (or how the system *thinks* the key
is set) you should be getting *something* when you connect to S1.

Long story; but details are posted at
http://home.globalcrossing.net/~osypher/keyless.html
All I can say, is when IBM said "high security lock subsystem (RS/6000
Support's words, not mine)" , They were definitely not lying. I've had
deadbolts on steel doors that were easier to bypass.

The switch itself is an 8 position single pole rotary switch. There are
three wires, red, white and blue connected to the switch. One of the
wires, not sure which just yet, is common, with one of the others for
service, and the remaining for secure. So without the lock, you have a 6
out of 8 chance of running in normal mode.
