Could be this one http://stason.org/TULARC/pc/graphics-cards/E-H/GENOA-SYSTEMS-CORPORATION-Monochrome-CGA-EGA-VGA-S-61.html

Or probably this one http://stason.org/TULARC/pc/graphics-cards/E-H/GENOA-SYSTEMS-CORPORATION-EGA-SUPEREGA-HIRES-MODEL.html
because the switch location is nearer to the switch location on the pic you referenced.

Both of these have jumpers located in different locations than the pic you referenced.

ok, thanks, it seems to be the second one, but without switching JMP3...interesting that in the CGA mode system reports only 16 kilobytes of memory, but when EGA 256 kilobytes

That sounds right, CGA uses 16k and EGA uses up to 256k if available. That video card was high end hardware and probably quite expensive.
