LS-212: An unauthorized OPL clone of unknown origin that was very common. So common even Creative used it in cards that you would expect to find the real deal. It is awful, it sounds numb, stay far away. The LS-212 is supposedly a pin compatible copy of the YMF262-M according to this article . It …
Re: Windows 2000 slows down after installing PCI card
Posted on 2023-01-29, 18:17
That was one of the first things I tried yesterday, and didn't make any difference, either in IRQ assignment or speed. But I just tried it again, hoping /PCILOCK would help, and after rebooting I noticed the card got assigned its own IRQ. Got excited for a moment, rebooted again, and everything is …
Windows 2000 slows down after installing PCI card
Posted on 2023-01-29, 01:13
Got this SW1000XG card today, but I'm having some issues with it. It makes cool sounds all right, but Windows is now unusably slow. The 3D Pipes screensaver runs at about one frame per *three* seconds. Now I noticed it assigned the graphics card, USB controller, network adapter, and the SW1000XG all …

Is there any more reason we know now of why the sound is muffled when using native ESFM? Is this a driver bug? I assume you mean muffled PCM voices? The FM synth has nothing to do with that. The PCM part of these chips is actually well documented, and they have adjustable filters. My guess is that …

Thanks everyone, appreciate the compliments. I just found some more registers and will document these shortly. Thank you very much for documenting this! BTW, we've been testing some games with native ESFM support in this thread . It can sound really nice when the developers use it properly. I think …

Hi all, Haven't visited these forums in a while, but I've been working on something that I know some of you will find interesting. You've read the title so you know what it is. I figured out the ESFM register map. As far as I'm aware, this hasn't been done before. I published everything I discovered …
Re: CF Card Through IDE - SLOW!
Posted on 2015-09-20, 17:42
Does your CF adapter have jumpers to switch between 3.3 and 5V? There should be a voltage regulator chip too (or two diodes, on cheap adapters). If not, it's most likely running at 5V.
Re: CF Card Through IDE - SLOW!
Posted on 2015-09-20, 16:02
What voltage are you supplying to the card? Some (many?) CF cards require 3.3V for DMA mode, and default to slow IDE/PIO mode on 5V. The DRQ/DACK signal lines must also be present on the CF->IDE adapter in order to support DMA mode. On older/cheap adapters these were often omitted.

I like the way this looks in 40-column over composite. And aaargh this game is too addictive. My best so far, who can beat me? 😀 (Epyx v1.49 btw)

Hacked my IBM 5150 mainboard to disable onboard memory and parity checking :) Nice job. I'm guessing you did this to use an external 8 bit memory card instead? That's right, although I disabled the on-board memory mainly so I could drop these chips in another computer. Only after modding and …

Yep, and also checked the big caps inside, they're all <0.05 ohm ESR. Could probably last another 30 years without servicing 😀 My brand new seasonics look bad in comparison...

Wouldn't a decent partition tool in a modern system be able to align partitions, even if its a FAT one? Windows 2K/XP/7 doesn't. Mkdosfs claims to do it, but really doesn't. Sorry to correct you but windows 7 does align a partition. Only exception are striped raid setups.. Tested lots of them after …
