It is. The VT131 has additional firmware.
In the meantime, I've found my VT100 manual. A flashing "4" means keyboard
faulty or nort present. For completeness, "2" means a memory fault, and
"8" means a data error. "6" is the logical OR of "2" and "4", etc. If
only the keyboard test fails, the terminal should go online in receive-only
mode (ie it's useful as a display).

That's exactly how one of the modes on SGIs with CrystalEyes shutter
glasses works. Even lines are on one frame and odd lines on the next, if
the image is interlaced. The shutter glasses use the vsync pulses to
switch sides between frames. That's why I suggested looking for
information about CrystalEyes. The difference is simply that in the
shutter types, you shut out one eye on odd frames and shut out the other on
even frames, while on LCD displays you display one frame (eg, the odd
frame) on the left and the next frame (even) on the right. Either way,
interlaced or not, it's alternate frames to alternate eyes.

It's working guys. Thanks a lot for all of your help.
In the interest of public information:
The BNC connectors do, indeed, carry composite video.
These (at least the model I have) contain a "kill switch" in the little add-on that's bolted to the back of the machine. In order to get power to the internal power supply, you must have the switch depressed -- or the "cover lock" bolt in the locked position.
Thanks again guys.
Err -- anybody know a good way to run some diagnostics on the machine? :)

Hi everybody,
In preparation for my eventual booting of the IRIS Power Series
machine, I pulled the back off yesterday and inspected the power
supply, etc.
It appears that somebody disconnected several plugs and some
screw-posts when they pulled the unit out of service (!)...
Anyway, to make a long story short, I had to make several
assumptions in order to get the thing back together. Here they
are, and can anyone confirm or deny them?
The square-ish plugs should all be plugged in to the plug they
match. (I thought this one was pretty safe.)
The three loose post-screws go to the three wires that were just
floating around loose (coming directly (more or less) out of the
twist-lok plug. These screws are labeled N~, L~, and <earth
symbol>
The Earth pin on the twist-lok plug is the longer one. (made sense
to me, but I can't find anything to confirm it...)
The L~ probably stands "Live" or something like that (?)
The N~ probably means "Negative"
The positive lead on the twist-lok plug is the one that has the
breaker on it.
Given that logic:
The L~, being positive, should be attached to the wire with the
breaker in it.
The wire connected to the long pin on the plug should be connected
to the <earth symbol> connector.
The other wire should be connected to the only loose-screw left.
There is further evidence in the way the wires were bent, which
suggests that this is all correct.
Has anyone see these things before, and can possibly confirm this?

Yup, that's it! Anyone claimed it yet? I'd like it for my RT.

I gave it a shot...I can't find any way to tell the scope what address
to use for the printer. When I tell it to print, it says "<HP-IB> No
listeners - Transmission Aborted". I assume this means it can't
directly address an arbitrary HPIB device, only something set to
"listen only"? This is the only time I've used HPIB and had things
not "just work". :)
I can set the scope to talk only, listen only, or talk/listen. In
talk/listen mode it allows me to set its HPIB address, but not in the
other modes.
Any suggestions?
Thanks,
-Dave

Indeed, I've been lead to believe that this was the case.
I've been assuming that is correct for now.

No identifying marks whatsoever, that I can see. :/

Thanks for the links. I'll see what they can tell me.

If it helps, the VT131 manual lists the following for
the print set:
MP-01066 VT101 Family Field Maintenance Print Set
That really is VT101 and not a typo (unless they
messed up in the manual) so it looks like
the VT131 is a modified VT100 series terminal.
I've missed the rest of the thread ... is there
a part number on the keyboard?
There is a pocket service guide for the VT100 at:
http://208.190.133.201/decimages/moremanuals.htm
(I've since found an original, so I can probably do
a better scan at some stage).
There are also two directories worth of
VT100 stuff over at:

Your best bet is ask in the apple // newsgroup where you could get a correct

Possibly -- I don't remember the branding right off. The problem, though, is that this is the only vt100-looking keyboard they have. :/ So if it's not the right one, (my current assumption until I figure out something else), then I'm at a loss as to where to find one.

Mine does that too -- the same flashing 4 I get when the keyboard _is_ plugged in. :)
