Note that I have had to raise the price somewhat recently. Check here for more information about this and my projects in general:

Gravis Ultrasound with WaveTable ROM and mounting bracket. I have a slightly cheaper version on offer too that does not include the ROM:

A black plastic bracket is included with the board as can be seen in the pictures. If you want a metal bracket, they can be found here:

Naturally, if you purchase this board and a bracket at the same time, I will ship them together and only one of the shipping fees will apply.

The board is an exact replica of Gravis Ultrasound PnP. All components are brand new, with the exception of the Interwave chip which is AMD original from the 90s.

Note that you will need a 72-pin SIMM in order to use the board. It supports up to 16 MB, and RAM is cheap these days, so I would recommend nothing less.

Here's the board running the DOS demo DOPE by Complex from 1995 on a Pentium-90:

Here is a link to where I run Pinball Fantasies on a 386sx-16, which might be a little slow for a GUS board, but it does work:

Note also that the power LEDs on that board are ridiculously bright. I have modified the board since I made that video so that it is a little dimmer now and more pleasant to look at. I also updated the SIMM connector to something a little more robust. See the first picture above.

If you have any questions, don't hesitate to ask!

Note that these boards are finished, tested and ready to be used. No soldering required, naturally. :)

Thanks for looking!
