i would have taken out the top slot cover with the gameport and the large serial port. Today i normally use just one serial for a mouse so i dont need a second one for a modem or else... and the sound card has a gameport.

Could it be a problem with the power button in that new case? Try shorting the two pins on the front panel header to start it rather than using the button. Along the same train of thought, try disconnecting all the front panel LEDs/speaker/IO as well. Edit: just realised it's powered on in your …

Haha. I forgot that i dumped all of this. I have a 2950 too that is not detectd. I flashed the Pnp eeprom from the working card to the one that doesnt work, because the content was different. but it still doesnt work. I have desoldered the chip and flashed it in my eprom programmer. Its strange that …

It's been many years since last time I bough a mystery box with unknown parts inside it. Finally I found one again. Actually I bought a Voodoo 2 and asked if the seller has some other stuff as well. He offered to send me a box full of older stuff and then we can negotiate a price later for the …

Here's how the front and back look close up, ignore the possibly shorting loose traces wires, those will get secured once I know things work. finished trace rebuild.jpg I see no reason why it shouldnt work. That looks great. :thumbsup: edit: Ok maybe i see a reason near JYEN jumper... traces seem …

...OR using these chips as midi only with a DAC to convert the digital output... Hi, thanks for the suggestion, I was thinking more about using a DAC, because those cards you said are non-existant here. I think the Y1 component of the 1st photo is a crystal. What DAC chip could I use? I could try …

maybe you could get a ESS ES1868F card with missing wavetable chips like this one for example : http://www.amoretro.de/2012/09/labway-ess-audiodrive-es1868f-pnp-isa-soundkarte.html That would be the option involving the least amount of work. If you have a look at the datasheet i have attached, you …

For example, a $3000 high-end gaming rig back in 1999 is about the equivalent of $5500 today. Even spending $1000 today on that same rig, it's still 1/5th of what it would have originally cost. To be fair, all of the stuff we considered high tech back in the days was e-waste a short time later... …
