Monochrome LCD Panel for Overhead Projectors

Saturday I came home from the flea market with a portable DVD player I got for just 5 Euros! In the evening I showed it to @Nikokaro, who, instead of being happy with me, had nothing better to do than telling me, that I buy broken and useless stuff just because it is cheap… and I could as well collect garbage in the junkyard! Gave him a well-deserved "😡" for ridiculing my attempts to collect/preserve outdated stuff!

If a perfectly working portable DVD-Player is broken and useless junk… well… let me grab something else from "my little private museum": A monochrome LCD-Panel with VGA input that goes on an Overhead projector. How is that one, Niko? :creep:
The text above is meant in a joking manner. Sadly my experience shows, that I am only funny to people when trying to not be funny and vice versa, so I had to add this disclaimer.

@M4x1mumReZ, maybe you are interested in this since you participated on the profile message?

Bad contrast, no colors, limited to 640*480… but hey: It allowed showing the computer picture in huge decades ago. Came in a nice protective pouch.

Due to the age there is some dust and whatever in between the glass and the actual LCD. I would have to disassemble it to get a bit better picture quality… but I don't use this thing anyway, so why should I? Too much work and it could get damaged.
The compressed photos do not represent how it looks in reality. When the room is dark (weak projector lamp), picture is still not pretty, but usable.

I chose a fitting computer from that era: 80386 CPU, 8MB RAM, 512KB ISA graphics card… and it has a double speed CD-ROM drive on one of those proprietary, special controller cards. Running MS-DOS 6.22 and Windows for Workgroups 3.11.
At first the PC didn't want to turn on, but after a targeted punch on the power supply, it started. Hard to take a picture of this. And I even had to choose portrait orientation.

Just thinking… if this thing wasn't black/white/greyscale but greenish like the DMG-001 it would be more stylish… playing with a GB emulator.

This definitely looks old, it's most likely from the 90's..
"but I don't use this thing anyway, so why should I? Too much work and it could get damaged."
Yeah, the ol' "If it ain't broke, don't fix it! " fits here..

No way I'm gonna open this! Where should I get another one in case it breaks?
Okay, some of the stuff I store on the attic does not work anymore (MFM hard drives like the Seagate ST-225 with 20MB) and is just for illustration. But as long as I can keep things working, I do.

The pretty much only reason to take out this projection panel was showing @Nikokaro something which is way more useless, nowadays compared to a portable DVD Player.

And it took me an hour to prepare all the stuff.

You make me to remember the days as student on college, I was working post time on college's IT department and one of my functions was install lots of these on the existing projectors at class rooms. Was the latest tech of the time and a great thing for the teachers and students. What a days!

@KleinesSinchen In response to your @, which profile message are you referring to exactly? The one with the DVD player?
Yes, of course. Nikokaro was a bit sarcastic about the portable DVD player, so I thought it would be the best to show him something with less everyday usefulness.
Was just a guess, that you might be interested in this LCD projection thing.

If you are willing to replace the monochrome screen with the one from your portable DVD player, you would first need to reverse engineer the I/O signals coming out from the LCD displays and also look up a datasheet for your screen (if you happen to come across one).

How about "no"?
This is way above my skill and would destroy two working devices.

Not a joke: I store a lot of grossly outdated stuff in original condition in an effort of preserving.

It shouldn't be too hard to find a more modern but still old/used projector with 1024*768 resolution which is enough DVD playback and presentations.
