Excellent work! Any progress on the Win9X driver?

You might want to check VideoGamePerfection's forum, since they're the ones who develop the firmware for the OSSC: https://videogameperfection.com/forums/topic/ossc-pentium-233-mmx/ You may need to adjust timings or configure the OSSC to pass-through higher resolutions, or only use 2x upscaling, …

Re: Post your favorite video game cover (MS-DOS/Early Windows edition)

My personal favorite is Quest for Glory III Wages of War. When I was a kid, I actually took the sleeve off the box and pinned it to my wall, along with some others of my favorite games. They eventually became sun-bleached and I had to throw them out, but I've since re-purchased these games with …
Re: Cracked PCB Connector Help
Posted on 2021-02-04, 04:46
acrylic or plastic cut to fit the connector, paired with a non-conductive epoxy would be the way to go. if it were me. I'd make a piece that fits inside the connector snugly to act as an inward brace and prevent deformation and buckling, the outer brace, apply epoxy, and clamp until cured. The only …
Re: Which VLB Video Card to Keep?
Posted on 2021-02-03, 18:55
I think you should keep the card that has better image quality on the monitor that you use. A 5% benchmark improvement is nothing to brag about if the display image looks like trash, either because of signal interference or poor compatibility with your software. IF money is your motivation, you …
Re: Need Help on Choosing Roland SC-55
Posted on 2021-02-02, 17:02
This is something I did not expect to exist outside PCs... I mean, you can't just use an emulator to run every game with an external MIDI device/engine, right? This is actually taking a rom, and ripping the midi file and soundfont from it, then loading it into a midi player with the output being …
Re: Need Help on Choosing Roland SC-55
Posted on 2021-02-02, 05:13
If you're only using it for games, any version of the SC-55 is going to work fine. If you want to do more interesting stuff like loading Gameboy Advance music files into it to create high-quality remasters of them, you'll want an SC-88 Pro. See this for an example: https://www.youtube.com/watch?v= …
Re: FX-3000 motherboard won't POST at 40mhz
Posted on 2021-02-01, 22:45
I have an FX-3000 as well, and it works fine with an AMD 40mhz 386 processor, but not any 486 processor I've tried. If you reversed the position of the 386, then you definitely shorted it, since pin A1 is VSS, and the pin the the opposite corner is ground. If you can, try another processor. Before …
Re: FX-3000 motherboard won't POST at 40mhz
Posted on 2021-02-01, 22:05
You've tried with a different 80mhz oscillator, right? The heat from that short possible ruined the clock crystal. Since you can post at 33mhz with a different crystal, I'd try getting a new 80mhz one. The CPU may be damaged too, since if you did have it in the opposite orientation, you created a …
Re: Let's talk about our hated trends

1) Tempered glass on modern PC cases. I dislike case windows anyway, but it's so much worse when they add 10lbs of weight and the chance of them getting shattered during shipping. 2) Front-mounted radiators. Why would you want to pull heated INSIDE your case? It seems like the more logical step …
Re: What is the best DOS gamer setup for Orpheus w/ Dreamblaster X2 ?
Posted on 2021-02-01, 18:23
If you can't figure out something as simple as how to use a standard ISA card with simple fire-and-forget drivers, how to hook up speakers to an industry standard 1/8" TRS jack, or alternatively how to hook up an audio amplifier to a standard 75ohm RCA cable S/PDIF, then I think you might be in the …
Re: I de-CQMed my AWE32 PnP CT3990...!
Posted on 2021-02-01, 15:11
Nice project but I kind of disagree with OPL3 being the holy grail of FM Synthesis, to me ESFM and even Crystal FM sound better, and CQM is not worse than OPL3, just different. Also, OPL3 by itself means nothing, the kind of filtering different OPL3 cards have tend to produce completely different …
Re: Orpheus Soundcard: a new DOS soundcard with SPDIF/OPL3/MPU support

This is probably a dumb question, but your eeprom has the 55h/BBh validation bytes at the beginning, right? Also, did you read the section of the datasheet detailing how to bypass PnP using sending a 32 byte key to 0279h to force the chip into configuration mode? It's on page 19 of the datasheet. …

But does it use the External FM? If so, you might be able to check the driver for differences and Frankenstein something together. Also, did Furan check CWDFM.DRV? It may be that the FM section of the driver controls it. Another avenue is to look at the PNP configuration data, the datasheet mentions …

Yes it should - furan looked at the driver but sadly none of what was discussed worked for me: https://www.vogons.org/viewtopic.php?p=911805#p911805 interesting info about the S32A , I wonder what happens under windows - is it sure that the 9233 still responsible for FM? do you have a link to it's …
Re: Orpheus Soundcard: a new DOS soundcard with SPDIF/OPL3/MPU support
Posted on 2021-01-28, 19:51
sadly it is of no use at all - it is really limited in what you can do and it only works briefly for experiments as the windows driver immediately reverts any such change it really needs the main driver to be patched - something that noone so far was able to do... That's unfortunate. According to …

Re: sb live! disable sb16 emulation

No, the registry key is for anything that uses the Emu10k chip. This includes the Live! AND Audigy line. I know this because I have an OEM SB Live! card that never installs the SB16 emulation drivers and provides no DOS sound in windows until that registry entry is added manually and the drivers are …
Re: weird idea, multiple CPUs on switching board?
Posted on 2021-01-26, 23:50
So, drive the BOFF pin and HOLD and AHOLD to their respective active voltage levels via a physical jumper or switch, and that might do the trick, huh? Might be neat to design such a thing. It's a niche market, but it could also be used to provide voltage regulation to normal Socket 7 motherboards to …
