Maybe that keyboard can work in PS/2 mode with an adapter? I tried the keyboard with a passive adapter, but it does not work . An additional curiosity;running the game under Windows 98 SE results in the game giving a warning at startup, but also solves the issue with the USB keyboard . Running a …

Interesting . Out of curiosity, what motherboard are you using and do you know what model PCI bridge chips your video card and motherboard (assuming it is using one) are using ? I am wondering if perhaps your PCIEX, PCIEX-PCI, PCI-PCIEX, PCIEX "sandwich" might be PCI 66Mhz capable, but your BIOS and …

I just ordered a Roland VS-880EX from Japan to replace my Akai DPS12, which I have been using as a mixer . The reason for this is the "issue" discovered and described in this thread : https://www.vogons.org/viewtopic.php?f=62&t=76589 The VS-880EX is not perfect and it definitely is not new, but a) …

I ran even more tests using a 1 KHz test tone . The low frequency bump is still there . Should I consider junking the DPS12 and getting a proper modern mixer ?

I think that something may be off off with my DPS12 . The GUS is nice and quiet while playing nothing, except that low frequency bump, same as my other sound cards . So I tested a pair of my DPS12's analogue inputs with nothing physically connected, but the said inputs enabled . I still get that …

I got my powered S/PDIF splitter today, so I thought I would run some preliminary tests, informally . Some disclosure first : a) I am no expert in this, so if I am doing it wrong (or you suspect I might be), please let me know . b) All audio from sound card line-outs is digitized by my Akai DPS12 at …

Modern PCI Devices run 66Mhz, 266Mbytes/s if you don`t have a old Device with 33Mhz inside at same Time. "Modern" parallel (legacy) PCI devices do not really exist anymore. If you are referring to the last native parallel PCI cards that were produced, some of them, like disk controllers, were …

Hi, I'm trying a Geforce 210 512mb ddr3 into an old but modern dual core 1.9Ghz/ddr3 industrial mini-itx board. The board has only one single PCI old style connector and I thought to try pushing its limits with this card being theorically faster than the on-board one or the FX5200 PCI I already had …

Assuming for a moment that this sampling method is agreeable (as it is to me, when I use DOS systems on my LCD panels via VGA), why aren't there cheap solutions that do it this way? How cheap do you need it? I paid like $40 for a VisionRGB-PRO2 and $150 for the VisionRGB-E1S. Someone in the US …

As mentioned in another thread, I ordered a NOS OEM AWE64 Value (CT4520) to test whether the craptastic line-out noise performance on mine is typical or if I have an outlier . My unit has low volume pulsing noise (probably below -60dB, I did not measure) on line-out which my CT4520 does not . Which …

I just remembered that I have another CT4520 installed in an Asus P3B-F . I tried recording from EMU8000 input just for kicks . It's actually worse, noise-floor wise, but a bit less annoying than that 1KHz tone . Those AWE64 cards can't all be bad apples . EDIT: Or maybe they are all very …

Curiosity got the best of me, so I ordered a supposedly NOS (large batch being sold) CT4520 . Piece of advice, check your CT4520 for the Vibra distortion bug . Doom offers an easy way to test it. Mine has it, and it manifests whenever the in-game volume for digital audio is above 50%. This is very …
