Also, is it any good? - the chipset is Tseng ET3000AX. Thanks for any info.
BTW, has the VGA connector always had 15 pins?
5 clock signals? 🤣
I think this is not a normal VGA card... any model info?
I'd say so. I have a couple of dual EGA/VGA cards myself.
VGA is 15 pin and EGA/CGA/MDA/Hercules are 9 pin.
You'll need to set the DIP switches for the correct output mode, maybe stason.org will have the settings.
EDIT: keropi's got a point, 5 crystals on that card is unusual. But without seeing a circuit diagram who knows what they do?
My ATI Wonder EGA card has two crystals, I've seen some other EGA cards with three. Perhaps the extra crystals are there for the different sync rates of VGA? or they could just be for the card's video RAM or something else.
a thought occurred on the crystal usage DK described:
what if the card uses crystals depending on user selection?
for example 2 for vga and 3 for ega mode...?
either that or the extra crystals are for the 9pin output that is for some custom use or something...
Early model VGA Wonders have 4 crystals as far as I know.

Interesting situation. Thanks for the info. Sorry, but I don't have any other info about this curious looking card.
Having several crystals on an early VGA/EGA card is not uncommon at all. Just check a few cards from 1988 to 1990.
RG100: This card looks quite usual. Socketed RAM, Odd/Even BIOS and DAC. Just compare with this Trident f.e. and you'll see: http://mail.lipsia.de/~enigma/neu/pics/trident_8800cs.jpg

Thanks! 😀
hmm an anctual ega card, gotta have one to resolve some weird mysteries about the ega emulation of vga cards being incorrect 😀
Do you mean for DOSBOX? I have a spare I could donate to the cause.... its just a crappy old Paradise.
funny enough I found this in my box-o-cards:
4 clock signals... crazy! :p

Well i couldn't hook it up to a VGA screen anyway. Doesn't seem there are many people who still have a working ega setup. Would be nice if there's someone that could at least run some test applications to see if the EGA really had a different palette in certain modes compared to what the VGA sets them up with.

Well, whats not presently available might be just assembled on demand. You have to decide though, what EGA or VGA/EGA card you'd like.

well I do have a working EGA rig and I'd be happy to run whatever tests you need 😀
Well, I for one approve of testing EGA cards for further DOSbox development.

Well that made me laugh.
Well, we all had a good laugh. Now back to work everybody, helping retro 100 and harekiet
Well, I have two EGA clones and a sufficient number of monitors...
A large number of crystal oscillators just indicates that it is a SVGA card from before they started using PLLs. A non-SVGA already has 2 of them.

Usual VGA/EGA combo card with 512kB memory from 1987. My bench results are:
8,7fps - quake 320x240
3,9fps - quake 360x480
5,9fps - pcpbench 640x400
23,1fps - pcpbench 320x200
Not only mine graphics cards collection at http://www.vgamuseum.info
to see if the EGA really had a different palette in certain modes compared to what the VGA sets them up with.
Along with that there are some funny side effects of games having added palette modifications for vga cards
whereas ega modes are used (and the games worked on ega), best remembered the warlords colors
for different parties (somebody even wrote them down here: http://www.pcmuseum.ca/details.asp?id=36762&type=software ).
