Re: Picking a sound card for a low-end 486

The story is rather simple: at some point, Yamaha stopped selling the OPL3 chip to OEMs. That's why big companies like Creative and others created their own version of an OPL3 compatible FM synthesis (CQM, ESFM, etc.). Many Asian companies did not care however and just manufactured the OPL3 on their …

Are those LS chips actually relabeled OPL3 or are they some clones that might sound differently? That LS-212 is a real OPL3, but manufactured without a license from Yamaha.

The DTV-1100 can probably be used with any card that has a LPB connector. PCI or not doesn't matter, as the DTV-1100 only seems to use ISA for getting power anyway.

These OPTi cards are also rather good. The original drivers are a bit bloated, but there's a community driver for the 929 that is just awesome. It does SB Pro 2.0 in Stereo and WSS. Your card also has a disguised OPL3, so not bad at all. I'm using a miro PCM12 in my P75 Plato build, which uses the …

Most games up to 1990 should run fine on it, also simpler stuff like adventures that are a bit newer (Day of the Tentacle e.g. still runs nicely on a 286). With DOS 5.0, Windows 3.0, and such games, you have a very nice 286. No need to try to reach 386 performance.

Sorry, thought you were using Win95 at least. In Windows 3.1 however, you can just install the SB 1.5 driver that comes with it. At least to see if there's a problem with the hardware or just with the driver.

because thare are only two isa slot, one for ide controller and one for sound card... no space left for VGA, or is better to use a isa vga and the internal ide controller? Actually, with only two ISA slots, I would not touch the system at all and leave it as is. Add a sound card and let it be the …

Retrobright is ok, just we should use a protective layer to slowdown the degradation. Maybe a good uv/abrasion resistant paint would be the best. Vinyl dye? It makes no sense to retrobright if you apply paint or dye afterwards anyway. Just save your time for retrobrighting in this case. Personally, …

I plugged in the ESS card and its PCM audio output is completely garbled in Windows (and only in windows - digital sound in DOS games is fine) as well. Check the driver settings in the device manager (there should be an extra tab with options). I had this too in an 486 and had to tick an option …

That's my board: I've installed a P75 and using the turbo switch to select between 75 and 90 Mhz. I've also attached the last BIOS released for the board.

I don't think you can compare WB and WT if the options are a DX2 WT and a DX4 WB. WB is slightly faster (if you can get it to work stable, which depends on the chipset), but the DX4 is faster anyway.

I used WinOnCD 3.x back when I had Win95/98. You need the retail version however, as the OEM version also only supports certain drives. Your version of Nero is probably OEM, too. My first cd burner from Yamaha (1997) even came with a separate floppy disk containing the MMC driver required for these …

Check the constrast knob using an ohm-meter, also check the soldering points. Could be that it's stuck at the lowest constrast.

MBR damaged for example. During installation, it should ask to create a rescue disk for such a situation. You can also re-install it, but afaik this will wipe all data.

Well, all I can tell is that the brightness is too high once the background starts to get brighter (i.e. no longer being black). Does the contrast knob do anything? Could be that this one is broken, which would lead to exactly that behaviour. Before messing with the monitor however, I'd recommend …

Personally, I like the ALS100Plus+ and using it in a 486DX4-100 build. The ES1868F is a good one, too. However, for a low-end 486, I'd choose the ES688FC OPL3. It fits best and nothing can beat real OPL3 anyway.

Exactly, that's the retrace line and always visible if you turn the brightness all the way up. Turn the brightness down and adjust the contrast, the monitor is probably just fine.
