ISA slots' signals are in parallel therefore having more ISA slots is just a matter of plugging an old ISA slot riser or similar backplane to have more ISA slots when needed. Even though i did what you described by adding a 2 slot backplane to my main machine motherboard, doing this type of thing …

Hello there! I've been rocking out an Orpheus II prototype with great results so far. This is a "dream come true" card for me. Its pretty much if you had an Orpheus 1 + a GUS PnP . That setup however takes 2 ISA slots while this card obviously takes only one. You know that motherboard you wanted to …

Back in the day, in 90's, Amiga 'elitists' considered IBM compatibiles inferior machines that lacked soul. Here, in Poland, they even called PC 'clones' and their users 'clonards'. Amiga fanatics can be annoying as fuck. Let's face it, the Amiga was a multimedia PC ahead of its time. Great …

Handling more than 1 PCM sound at the time will definitely require real-time mixing; as you said, Gravis Ultrasound support for hardware-based mixing (I believe there's a mod called "UltraWolf" for this, which I have never tried because I never had a GUS), or a DMX-like software mixing solution ( …

Having the turbo button is much more important than actually using it. Somebody needs to convert their turbo button to actually live up to its name. De-Turbo should be the rated system speed, and pressing TURBO should activate water cooling, powerful (and loud) exhaust fans and overclock the shit …

Thank you for linking my Video. Now if you try to just drive the CPU clock form an external clock... well this will never work. And there are many problems with that. The bus is sampled based on this clock. So all devices connected to the bus (CPU, Chipset, etc) should have exactly the same clock …

Hi, tried this mod for the first time and it is absolutely great! I wonder if some enhancements are still possible, like on the sound engine part. It seems that still the engine can only handle 1 PCM sound at a time. Is it possible to improve on this? Or maybe add Gravis Ultrasound support which can …

I agree this is a cool project but why not use an FPGA? FPGA design is not simple, and here, any part of DOSBOX or other software emulator can be used. On the other hand, a big enough FPGA, could support several sound cards as once. Synth chips like the OPL3, dual OPL2's could be done in FPGA, its …

has somebody any good advice for the best way to steer the plane? According to my experience (36 hours) of flying real airplane: 1. Keep an eye on airspeed. Don't let airspeed drop below stall speed +10 kts. 2. Too much bank. Try turning with not more than ±15° of bank. 3. Don't pull so hard on a …

I said run it to the clock gen not to the crystal. We said the same thing I think. Anyway, there is usually a 12 or 14mhz clock for the kb clock on the clock gen chip (pll) You could use a coaxal cable maybe btw. Like a wifi cable? Help insulate from interference. Ground the jacket, use the core …

The fastest way to test this is probably to de solder the clock pin on a pentium mmx and run a boge wire from it to the reference or kb clock on the clock gen. And boom, your fsb goes from 50/66mhz to 14 mhz You can't just run a bodge wire into the reference clock. The 14.318Mhz crystal does not …

I believe that making it external would possibly have to tap and sever all the bus lines, translate it to a higher clock somehow, then attach to the cpu. My hipothetical idea is to divide the clock just before it touches the CPU. Dividing the 50MHz bus, let's say by 2, before the CPU and send it to …

It might be possible to use a device like this to disable L2 cache. but the mobo usually has a setting for that. however, I may have a clock related alternative for you. Many cyrix chips included a 1x multiplier setting that coincidentally, this tweaker can be used to set on older motherboards. …
