A matrix of holes does not always indicate a prototype card.
IBM sometimes put them on production cards if there was spare real estate.
An example is the IBM Game Control Adapter, pictured [here (http://www.minuszerodegrees.net/5150_5160/cards/5150_5160_cards.htm#game_adapter)].

Woah, on the ISA bus? That's pretty freaking neat.

Maybe others will 'chime in'. It does not look like a prototype. It may be from the first production run.

Is it right? Because could not find the iSA interface of the XGA images on the Internet.
Can only find Radius MultiView XGA in http://www.os2museum.com/wp/?p=1867

And said:
XGA Clones
For the XGA, IBM chose a novel strategy: Instead of making the hardware specifications secret, the register interface was fully documented; in addition, IBM licensed the XGA chip design to SGS-Thomson (inmos) and Intel. Worth of note is that Radius manufactured ISA-based XGA-2 adapters built around chips from inmos (as usual, IBM didnít bother with non-MCA adapters).

Looking for IBM images over the network, can not find the ISA interface XGA card, who has seen this card?

Only Radius Multiview XGA.
