Nice work, as always! If you happen to have one SimmConn to spare in the future, maybe I should upgrade my dusty AWE64Gold.

A technical note on the possible lockup with the Sound Blaster 16 cards, when using digital effects together with the build in MPU-401 Midi interface. This is a problem also found in other games. As discussed earlier the patch SBMPU401.EXE (inside waveptch.exe) offered by Creative prevents such …

I have seen that too. But that may be because of a lazy/uninformed former user. These boards have the 'voodoo jumpers' which need to be set for power hungry video cards, including Voodoo 3 and Geforce. If not then the VRM near the AGP slot will get very hot and the capacitors near it will suffer.

I may have given you a false alarm on the caps. I just partly recapped mine with new 330uF ones. I still had an occasional refusal to bootup, and then found that the board boots again when changing that red jumper J15 near the battery to the closed position. open= Soft Off (default) / close=Full on. …

Weird stuff. But at least there might be a solution in the line of what you are currently trying. What if you just switch the order of these two lines, like this:? C:\SB16\AWEUTIL.COM /S /R:10 /C:10 C:\SB16\DIAGNOSE /S The system that I was using at the time was i440BX based. Either from Aopen or …

ReactOS 0.4.6 has been released. The announcement presents a summary of the most significant changes and has links to more detailed changelogs and test results. Not much to add to that. I read about their 'Google summer of code' projects in the past months, like NTFS file system support. The logs …
Re: SB16, no MIDI out through gameport

In all the sooundcards that I have checked (quite a few): the waveblaster midi pin is hardwired to the DB15 port midi pin.

The CS4231 codec is well documented and very common: http://www.cebix.net/downloads/bebox/cs4231a.pdf It is practically identical to the Analog Devices AD1848 codec, as found on an actual Windows Sound System ISA card. The Windows Sound System ISA card is the only card I know of which has no …

Yes, it uses a dc dc converter that switches at a frequency well above audible frequency, and has low ripple. That sounds like a good solution. Your application does sound interesting. I'd love to hear more if you want to continue via PM. Oh, it is this thing I made some years ago (picture). It is …

Re: Why are old PCs considered lame and boring?

While I was writing my comment, and editing it, I was actually wondering. Could IBM have made a mode 13h with two pages with the technical limitations of the time? At first I thought yes, but now I am unsure. My comment was only resulting from your text 'VGA itself wasn't the problem.' I have no …
Re: Why are old PCs considered lame?

If you ask me, SVGA is irrelevant. 99.99% of all DOS games are standard VGA. VGA itself wasn't the problem. Lack of performance was. Amiga offered graphics that were roughly the same quality as VGA, but most games ran at a perfectly smooth 50 fps, where PC was slow and jerky. I would like to add a …

@dreamblaster I made a Voltage converter once for a similar adapter as the "Chill Limited Edition' V2 KIT". IIRC it made -12V out of 12V using an NE555 timer. But this method creates an alternating voltage that is levelled to the target voltage afterwards. The alternating current gave me audible …

I looked it up for you, the VRM does not mention Pentium III/VRM-8.4 compliance, but can supply 1.75 Volt nonetheless. "SC1185CSW" -> http://www.semtech.com/images/datasheet/sc1185.pdf -> "1.3V to 3.5V Pentium ll microprocessor supply" So the Vcore problem should not apply to your motherboard. (To …

No problem, but I think my previous post answered your voltage question already? All this is speculation, which may or may not apply to your motherboard, you have to first find the motherboard documentation and VRM datasheet. As for the performance, I don't know. The i440BX was told to be a fast …

There was an actual Windows Sound System ISA card. And it had an Analog Devices Codec. I don't see the card around much, so I don't think it sold that well. I don't expect your laptop to actually contain that ISA card (or does it?). But the actual WSS sound interface compatibilty is seen in many …
Re: Need some hardware assistance. Another mobo burns up.

I never dared to try that. My guess is: on a poorly prepared motherboard one of the Voltage request signals is unsupported and gets ignored, so what you may get instead is a totally unexpected core voltage. On a properly prepared mainboard it would detect 'voltage request is unsupported' and will …

Do these mainboards officialy support Slotted Coppermine-core Processors? Coppermine core normally requires voltages of 1.65 to 1.75V. But early Slot-1/Socket 370 motherboards precede this requirement. Do these mainboards UNofficialy support Slotted Coppermine-core Processors? Which usually means: …
