Quote from the site Vogonswiki.com (c):
"Unlike any other Ultrasound card, the GUS PnP is not based on the GF1 but rather on the Interwave chip made by AMD. It is hardware compatible with the original GUS when initialized in GUS mode but differs from it in several aspects. First, it is able to play back 32 voices with the full 44kHz sample rate, where the GUS Classic went down to ~19kHz. Second, the on-board sample R...AM can be extended to 8MB using SIMM, although the Interwave chip has an address space of 16MB. It also has a built-in effects processor and comes with 1MB of sample ROM filled with a GeneralMIDI compatible sound set.As the GUS Classic, the Interwave chip is neither SoundBlaster compatible nor has it an integrated OPL3 FM chip. The card only provides the SB control registers (0x220H, 0x388H, ...), the actual SoundBlaster emulation is done in software. To be fully compatible with the original GUS, some RAM has to be installed.Installing a GUS PnP can be quite a challenge due to its resource demand (three to four IRQs, three DMA channels, several IO ports). Fortunately these requirements can be lowered to two IO ports, two DMA channels and one IRQ when configured correctly. Prior to installing the card, any other soundcard and probably other extension cards should be removed from the system. They can be re-added when configuration of the GUS PnP is completed."My card has 8MB of RAM 2х4MB simm Hyndai ic + 512Kb in onboard ic. Fully tested in Doom and Heretic game - sound effects and music.Card in excellent working and cosmetic condition.Card solds without original packaging, instructions and original driver diskettes and CD. But i'm add non-original CD disk with drivers.
The card is verified by me, but it is ~30 years old. Therefore, i am very sorry, but no any returns or exchanges are not accepted.Make a purchase only if you understand what you see.
Attention - about shipping. I always send goods by airmail. And i provide an international track.BUT. For reasons beyond my control, my goods can be shipped by sea. It may be to Canada, to the USA, and in 99% of cases it will be to Australia. On the track, it will look like a very long time import. I am very sorry, but in this case you must to wait. The goods is not lost, it is on the way.Anyone who wants to get a quick delivery, can always choose a express delivery.
Any questions please ask BEFORE purchase. Thank you
