I picked up a Sharp QA-25 computer LCD projection panel from a local
junk shop today. The glass/"optics" look just fine (no scratches, just
needs to be Windexed), but I have no manual or power supply or data
cables for this. I remember using one about 10 years ago when in
school, but I dont remember if this uses EGA or CGA inputs (has a 9-pin
D-shell data input).
I'm guessing probably CGA; anybody know specifics on the data cable?
Think I can hook it via straight-9pin-cable to the CGA out port on the
back of a laptop and fire it up? (fortunately I can use a standard
generic wall-wart power supply; it has the specs and connector diagram
on the side of the unit).
Now, off to the office surplus store to get an overhead projector for
$10....

I have a Sharp {Idontremember} panel, black&white , 16 rasterized "shades"
of grey. The case is dark grey/black and there's a wide fan on the other end
and a flip-up cover exposing contrast and other controls. It can do
VGA and (EGA/CGA or Hercules) with the appropriate cables. It might have
been a QA-25 but I'm not sure. Came with a remote controller too (IR)
The controls were really small dials and a couple of push buttons.
I have the manual but I don't remember if it had the cable diagrams.
I bought it an auction three years ago, I was bidding for 2 Tek 4207's and
a 4107 and after paying the $10 I found the panel underneath the pile.
Now, off to the office surplus store to get an overhead projector for

.. and at the same auction I got three overhead projectors for $2. Sometimes
you get lucky (although I still don't know what to do with them).
I like playing this PC racing game "Stunts" projected to a wall. So that's
my recipe for 12 buck multimedia "experience".

The QA-25 was quite pale in colour, but was superceded
(very rapidly) by a VGA model in black plastic. This seems
to be the one that you've got. Sharp UK were most unhappy
to find themselves with stocks of the earlier model at a
time when the PS/2 had just come out, the VGA was the "in
thing" and their old LCD panels wouldn't work with it.
The controls were really small dials and a couple of
push buttons.
The small dials were for adjusting the gain of the three
colour channels of the (analog) VGA input.

It had to happen sooner or later... a device that I worked
on would appear on ClassicCmp...
I was working for London Software Studio in about 1986 or
1987 when we were asked to adapt our presentation graphics
software for this very LCD panel. My colleague, Beccy
Holmes, did most of the work of modifying a compiled BASIC
program from EGA colour mode to CGA mono mode. I helped
with a CGA 640x200 graphics library, mostly in 8086
assembler. Sharp UK bundled the code with all the LCD
panels that they sold.

It's CGA. The CGA video connector was a 9-pin, and it just
needs a straight-through cable to connect it to a CGA card.
I'm guessing probably CGA; anybody know specifics
on the data cable?

Yes, should be OK.

I got an email this morning *already* from Sharp customer service;
they're mailing me a copy of the manual for the unit at no charge.
Talk about fast - I only emailed them around 5am this morning.
