Wondering if anybody has seen and used this beast before. The brochure
says "SUPER VGA", a 16-bit card using Trident Chipset. Then it goes on
and made the following claims. Many thanks to anybody who either
confirm or (unconfirm ??) these claims. Here goes .....

The above is reproduced from the brochure word for word (including the
spelling errors :-)). The Vendor name printed at the bottom of the brochure
says "AMCOM".
I am most interested in finding out if the card can be made to do
800x600 256 colors ? Which is theoretically possible with 512K of RAM.
But I have not been able to test the card with 512K RAM. I've tested it
with 256K RAM and it looks pretty good.
Any taker ??
