I've got this monstrosity as a bonus with some Ebay item awhile ago. Dunno if it even works -- I have no cable, no EGA monitors, and no information about this card but from the looks, it is four-monitor EGA. Four identical chips on the left are all 82C435 EGA controllers (http://www.datasheetcatalog.com/datasheets_pd … /4/82C435.shtml), the single square chip on the right is matching 82A436 bus interface. I can't tell if all controllers are addressable or they just produce the same output -- I think it's the second case even if it looks like a very inefficient design.
82C435 is actually enhanced EGA, capable of 800x600. If four chips on this card were individually addressable then it would be capable of producing equivalent to 1600x1200 EGA mode 😲
