I don't have one but I'm very intrigued by them. They were 386s made by Wang Labs shortly before they went bankrupt in the early 1990s. Anyways, my questions. Can these use conventional ps/2 keyboards? I read something about how they use a special Wang "vs" keyboard but wasn't sure if that was an …

Looking for the chipset might give some clues Looking at your first thread, and going with the 386 board there. It seems to be an opti 82c381/2 chipset This leads to https://theretroweb.com/chipsets/366#docs which has a pdf for download which on page 7 and beyond, lists some register information …

Hmm I don't know. I have no documentation for this board and haven't been able to find it on the retroweb. In any case, the current bios doesn't say anything about flashing or upgrading within the GUI.

I have managed to fix this, but not in a good way! What fixed the audio drop outs was changing a setting in my bios to run the CPU "slow" rather than "fast" (fast is the default, so this option is kinda like a turbo button I guess). So running the CPU slow fixed the audio, but since we're talking …

I have made another video comparing the musical output of SBOS 3.82 and MAXSBOS, two different versions of SBOS. They sound quite different, and in my opinion, the later released MAXSBOS is not a worthwhile upgrade! https://www.youtube.com/watch?v=y118o8UgCTU

Cool. Thanks. Is there any cache that can be enabled or anything else that can be adjusted on the stock PC to nudge it up a bit? By the way, I heard the game Xargon has a bug with the keyboard on this machine. Something like you move an arrow key to move the player and then the input sticks as if …

Could someone run 3dbench and tell me what the score is? I just want to compare the number to what I get with existing 386/486 computers I have.

I've got this option for atclk in the bios. Any idea if this might relate to isa bus speed or what I'd write in it? I have the option to change the 55h value, but I'd need to type something in manually, there's no selection of choices. Filename PXL_20240807_005854687_exported_99_1722992490064.jpg …

I found a reference to someone else having GUS playback skipping notes. Seems as some suggested it could be related to ISA bus speed, which I haven't been able to figure out a way to adjust on my motherboard From here: https://nerdlypleasures.blogspot.com/2016/10/reasons-for-owning-gravis-ultrasound …

It seems to me that the GUS's SBOS software is not well documented these days. For instance, if you search for recordings of music played by SBOS you will not find any! So here I am to remedy this with an hour long chunk of SBOS music from many popular games (Wolf 3d, Keen, Blake Stone, Jill, Major …

I haven't fixed my issue yet, but I did discover and solve another issue. If you have the Gus irq and recording irq set to the same value in the ultrasound variable , this seems to cause a few idiosyncratic problems in games when using sbos. Namely, in skyroads the music and sfx will play but the …

As I did not see it mentioned whether you tried it: did you try changing (increasing) the wait states for the ISA bus in the BIOS settings? And did you try any setting with just DMA channels 0 and 1? Thanks for trying to help 🙂 I do not see any settings in this pc's bios to make adjustments to the …

I tried playing the Jazz and OMF music, as well as unrelated mod files with Impulse Tracker and ran into similar playback issues as the epic games. If I were to describe the state of things right now, it seems music that uses the official gus standard samples (Doom, Boppin, GUS midi player, Raptor, …

I agree, the bad ram idea is completely out the window now. Good idea to try the epic tracker music in some tracker playback software, I'll try that to rule out an incompatibility with the epic software in particular (I think the Gus really seems to be working in other stuff like Doom and Boppin, …

I took the extra ram out. No change in my audio drops with some games. Is there an ini file or other thing I need to edit to ensure games treat the card as having 512k of RAM instead of the 1MB it had when I first installed it?

I used shadow ram with the xtide bios that was on my ISA lan card and I'm pretty sure that improved the drop outs a bit. I still have them but the amount of drop outs is not as much as the clips I recorded. Really starting to think the drop outs are related to the ISA bus speed of this PC and hoping …

It might help if you posted the system settings of you GUS MAX and your system specs. A few things to check are whether you are using high DMA channel for the GUS (4 through 7) and if you can change delay settings of your ISA slots in the BIOS and maybe also the ISA clock setting. Try setting the …

New update, doom and rise of the triad seem to work great in Gus mode. I also think I fixed my Boppin issue through a combination of selecting lower quality playback and fewer simultaneous sfx. So it's really just the Epic games that very noticeably truncate or don't play samples at this point. I'm …
