Can't get you the Wyse part number, but Altos (AFAIR) OEMed these terminals as the
"Altos III" terminal. Have one in the garage, gives good service. ANSI and TVI-910, with a block-mode
option. Haven't had to open it yet for any reason (already had a battery go out on a late '80s WY-150, so the
Altos seems to be pretty bulletproof). Unusual key layout, though. (not DEC VT, not PC101).
Some time back, I pulled apart a fairly trashed XT-class computer and one of
the things I got out of it was an LCD, most of it appearing to be fairly
standard stuff and I don't think that I'm going to have a lot of trouble with
that but then there's that other connector...
Two pins, and both wires are the same color.
It's been suggested to me that perhaps this is for an EL backlight. Any of
you folks know of how I might go about testing that, so I can get some idea
of what's actually in there?
Anybody by any chance know of this display?
Oh, and if it helps any the brand name on the box was "Western Digital",
which is the only time I've ever seen that brand name on a computer.

Hi,
Well folks, I haven't made any progress since I
last mentioned about my baby. I haven't got
a Voltimeter yet, but I am considering getting
one. However, I need to wait until after payday (15t
h).
In the meantime, I opened up my A600 and had
a look inside. I decided to do a rough diagram
of the chip layout and happened to notice
what appears to be a component missing. I'm
not entirely sure whether it was designed that
way, or whether someone removed it.
Incomplete Summary of my internals (I ran out
of time-I needed to sleep!):

Missing item from XU1 - there is an outline (in
white) clearly visible, with small circular metal
marks above and below where the component
should be. The outline looks a bit like this:

Anyone have any idea whether this should be
missing or not? Is it possible to get my hands
on the plans (schematics?) for the PCB?

Why mess with the low-end mini stuff? Build something with style, power, and 36-bits.
Or, be unconventional and do 37 or some other prime number.

Gee I've been sitting on 16 2901s... that should be enough bits for somthing.

The TI Professional almost-IBM-PC (in some ways better) used a Hall-effect keyboard.
Probably more expensive than the capacitive/inductive keyboards, but most likely the ultimate in reliability.
Better layout than the original PC keyboard, too.
There have to be some more designs that were so elegant or well-done that you stepped back to admire them.
What were they?
Hi,
Researching the early history of RAID.
Thinking Machines announced a product called Datavault circa 1987; it
was shipped shortly after.
A training video was made showing operation of the Datavault.
If anyone has it, I'd like to buy.
Please contact me off-list.
Thanks,
Steve

Lest we forget the WD Pascal Micro? The one with the WD16 chipset
programmed as a P-engine.

Dear all,
Trying to install TCPware on VMS 7.3. When I ask it to start the
