2xEGA + 1xVGA card switching identification

[romanon]

Hello, have someone switching identification to these cards?

1.


2.


3.


This last card have 9 and 15 pin output. 9pin out works on my multisynch EGA monitor like VGA on TTL signal, but colors are really strange...






On 15pin out card works like normal VGA card

1 & 2 EGA cards, for #1 just google for STB EGA Ultra, this seems not to be totally unknown.
3 a VGA card with Cirrus Logic chipset. Drivers for Windows 3.1 can be found here: www.win31.de

Why are all your photos upside down? This makes identification much more difficult.

Ehm, sorry for upside down pictures...I found something. First EGA have only first 4 switches to change videomode and they are same to IBM EGA schwitching.



2nd EGA is compatible with 5 switch, switches 6,7 and 8 are not used, so here is it



And finally card number 3. Very interesting card. It allows connect 9pin and 15 pin monitor. You can set up monitor type and also card type. Here is switching manual --> https://th99.bl4ckb0x.de/v/U-Z/50793.htm

For example i can choose normal 15 pin VGA monitor output, but as graphics i choose MDA or CGA. No problem.
