Hello,

I've already asked this on vcfed, but have not received any answers so far. So, I'm duplicating that thread here in case someone can help:

Does anybody have the pinout for the DE15 connector of this monitor for TTL configuration?

And what about these switches?

SCAN (WIDE/NORM) -> Maybe WIDE: 15.5-35.5 KHz; NORM: 30-35.5KHz (?)
MODE (NORM/PRESET) (?)
TTL COLOR (8, 16SAT, 16PAS, 64) (?)

Some links:

Thanks!

According to https://forum.atari-home.de/index.php?topic=281.0 (not too authoritative, I will concede) it was made by Mitsubishi .
Assuming that is accurate, you might get lucky and find an equivalent or similar Mitsubishi model for which more documentation has survived.

EDIT:
It looks similar to this Mitsubishi FA3415

And Schneider seem to have what is possibly a rebranded version :

Thanks! This is super useful! I will validate and post the discoveries and results in the following days.

Best of luck and welcome to Vogons!

You should take off the cover and see if you can trace it out because there are multiple ways of wiring TTL on a 15pin. You also need to be very careful you identify any pins that go to ground or any uncontrolled voltage.

One of my old screens with a proprietary connector and pinout had color coordinated wires going to each pin making it easy to know what the pin did.

The mitsu pinout is most likely but there is also an NEC pinout and the below pinout that are possible.

1=GND
2=R'
3=R
4,5=nc
6=VSYNC
7=HSYNC
8=nc
9=key
10=G'
11=B'
12=nc
13=G
14=B
15=nc

Yes, I will do a closer inspection and measurement before injecting any signal, and I will take the AOC pinout as a starting point.

I found the original cable used with this monitor for TTL video:

Label: CABLE-FA12

Pinout:

The pinout of that cable seems to match the Mitsubishi pinout.

That looks nicely sharp and well converged.
How bright is it ?

Brightness is good. Pictures were taken with brightness at 50%. I will soon upload some examples using different color settings.

Yes. And I don't see that the TTL/Analog switch changes H/V like the Highscreen MS 1024, so I guess the final Pinout for Schneider and Mitsubishi would look like this:

I think I'm wrong about RGB analog pins. After looking at the schematics from FA3415 I see that RGB analog signals are coming from E2 connector, so they must be using pins 2, 4 and 10 from DE15 connector; however, I don't see that connection in the PCB diagram. I will have to open and inspect.

OK. I was able to measure between E2 pins and DE15 connector using an ohmmeter, and this is what I got:

DE15 - p2: Analog BLUE
DE15 - p4: Analog GREEN
DE15 - p10: Analog RED

Correction for the above for Analog pinout:

DE15 - p2: RED
DE15 - p4: GREEN
DE15 - p10: BLUE
DE15 - p8: V-SYNC
DE15 - p9: H-SYNC
DE15- p6: GND

Tested with Amiga 500:

I created the following wiki with all the information I've found related to this monitor, as well as the tests I've done so far:

https://github.com/charlysan/crt_stuff/wiki/S … ltiScan-Monitor

Thanks for your effort but this monitor is so rare I doubt anybody else has it these days. Was is it sold mainly in Germany?

A CRT monitor that can do EGA/CGA and emulate MDA in a chosen color as well? I'm envious. Last time I saw something like that the price was very unreasonable and frankly, from the photos, the tube was spent (not to mention had minor scratches).
