I'm going through all my boxes of graphics cards I've collected over the years and 'discovered' a couple graphics cards I had forgotten I even had.
One is very similar to this one on ebay http://www.ebay.de/itm/Eizo-Accel-AA51-AA-AC5 … l-/191482985564 except that the one on ebay is ISA and is a REV C while mine seems to be MCA and is a REV B.

I don't have a reasonable camera, but I think the pic in the ebay ad will be sufficient 😀

From what I gather from the printed numbers, the card seems to have been made in early 1992 with most parts referring to 92 and the BIOS sticker having 1991 printed on it.

Except for the interfacing connector not being ISA, the other differences are that my card seems to be slightly 'lower' and on the opposite side of where the connector is for the display (it would be on the left side when facing the printed and chipped side of the PCB), there is a gray piece of plastic attached to the PCB which I think was used for seating the card into the system I removed it from many years ago.
The ebay one has "AA51" printed on the PCB while mine has "AC51" and the rest of the layout is slightly different, including the "VGA" connector (I don't even know if it is VGA or some other standard 🤣) being locvated nearer the bottom side of the card instead of being mounted near the top side of the card which is featured in that ebay add.

My card also seems to have the same little expansion PCB which is a memory expansion module with the exact same model name. Even the little sticker on the module PCB has the same colored dots as the one on ebay, but a slightly lower "version number".

Does anyone know what exactly this is and how useful or sought after it is? Since I don't have any MCA motherboards, theres no way for me to test it or to even see if it still works. I can't see any signs of damage or corrosion anywhere on the card though, only very little dust.

When I figured out the date, I was much surprised how modernish it looked, it seems more similar to graphics cards from the mid 90's for some reason, except the MCA connector already hinting at it's true age.

Whats missing in your collections?

Probably set card sold with some EIZO monitor. So it could have proprietary screen modes/resolutions/maybe even connector wiring. Before SVGA every monitor maker with better than standard parameters had to add its own graphics card. And many profi makers did same even years later for specific usage markets. For example i have 2 Eizo Enhanced MDA MD-B05 cards. These were for Eizo 4051WL-ED MDA like monitor, which had increased refresh rate (luckily found card and monitors together in one old PC). Still have monitor for trade, but many MDA cards wont work with this one. So card might work with standard monitor, but also could not. Who knows, since most manuals are lost and only one maker sharing info about his antique stuff is matrox.....

Yours card seems to be 2D CAD accelerator like more known TIGA cards. But with Chips&Technologies F82C480 chip. Here's smaller similar ISA version from Palcal's collection....
