 I don't want to hear it. The quadruple hernia
inducing Texas Instruments Portable Professional
weighs 2-3x as much. I got both . My SX is
broke
though :(

 Yep. And I'm probably the only person on planet earth
with a respectable supply of NOS picture tubes for
'em. I'd consider some groovy trades. But otherwise
NOT FOR SALE. THANK YOU VERY MUCH! I was considering
making some weird display out of 9 of them.

It is the second machine on this site :

I have no idea how many were made, but must seem to have
originated from 
the sell-off Siemens had after PDC went bust.

No color flat screens existed then... It was a yellow
elektroluminent 
display.

So how often do these show up on eBay? You're right, I want
one of these

is an electroluminescent display essentially a plasma
display? IBM made this huge amber color display that
was plasma IIRC. And it was essentially a flat panel
unit.

No.  EL displays use a phosphor embedded in a plastic
substrate 
between two electrodes, one of which is transparent. 
Excited with an 
AC voltage, the phosphor will glow.  You can sometimes find
EL "night 
lights" that glow a soft green.  Power consumption is
in the 
milliwatt range.

Not often. You will have to look in Belgian and Dutch
auction sites.
Prices were low, probably because nobody knows this machine.
I wonder if this will change.....

I don't. I was impressed with the EL display and not much
else.
That EL display was the first usable flatscreen I ever saw.
The Clipper itself was not ready for production.
It should, at the very least, have had a proper mainboard.

W.r.t. to EL displays : I never noticed milliwatt power .
A somewhat later Sharp unit LJ640U26 ( 640x400)that I
measured consumed 
close to 15 Watts.

Ah, I was referring to the small (perhaps 2 cm x 3 cm) green
EL night 
lights--the back of one within reach is stamped "0.067
watt".  
There's not enough light from one to actually illuminate
anything, 
but it does serve to show where the wall is when you're
wandering 
around in the dark...

There were high-powered ones proposed for applications such
as 
glowing belts for public safety workers and such, but
lifetime is 
limited because the phosphor tends to slowly "wear
out".  I remember 
a text on using EL coupled with CdS photocell material for
image 
storage and intensification--but this was back in the 60's. 
I don't 
know if much ever came of it.

A couple of years ago, I was talking with a Toshiba VP and
was 
surprised to find that he had never heard of the Toshiba
plasma 
display laptops.

Chuck

   No...EL uses electrons to excite a phosphorescent
material, while  
plasma uses...well, plasma! ;)  Similar to the way a neon
lamp works.

   I have one of those displays you're talking about; the
3290.  It  
is gorgeous.  I made some progress on getting what  I need
to make it  
useful, but then house sale/house purchase stuff started
picking up  
and I haven't been able to make any more progress on it. 
Soon, I hope.
