I set 2400baud,8 data bit, 1 stop bit no parity, xon/xoff and terminal emulation to TTY and VT52. The only thing I didn't try was VT100 and local echo, but even typing "dir" doesn't do anything And no, I'm not using an usb serial cable. I'm using a good old pentium 2 and it's serial port and I'm …

So the RTC/io board isn't healthy. I took another io board (16 bit ISA this time, so munch newer) and it booted. But I didn't manage to have ctty working ... It displayed correctly in hyperterminal, but when I typed stuff, it didn't do anything at all

Last month I came back with a lot of cool retro hardware. But I noticed an odd looking card that had a 386EX on it. It's the exact same as this one : http://www.ebay.fr/itm/Carte-applicom-PC2000ETH-/281115969663?hash=item4173d1487f:g:mxIAAOSwcUBYHHIO But what is it ? It looks a bit like some kind of …

Here are some news ! I received fresh capacitors for the HDD and japanese caps for the PSU. I said that the computer crashed randomly, well now it doesn't do it anymore. It's funny to see that 2016 rubycon capacitors are actually 2 times smaller than 28 years old teapo capacitors. However the …

And my sli of voodoo 2 works also perfectly on my pentium 2 with an overclocked bus at 37.5MHz. I think I even ran once my pentium mmx system with a fsb of 83.3MHz which makes over 40MHz bus and the voodoo 1 that I was using was still fine !

I'm not sure at all, but won't the coprocessor just run at the same frequency as the cpu ? How could 33MHz be generated with only a 25MHz quartz ?

There is no green wire to ground trick like on ATX psus. AT psus are sending power directly into the computer. The on/off switch outputs directly the 110v/220v into the PSU. When the psu is powered on, the computer starts up, there is no switch for the motherboard. If the psu doesn't start up, well …

I've got an HP vectra with a 486 DX 33. I remember that I used a DX2 66 at some point and it worked without any problems. The only problem with that machine is that the bios doesn't support LBA (but this happened also on regular boards) and maybe also the fact that I can't touch any of the timings, …

Yeah, I remember that when I used 8x drivers on my pentium 3 using either a tnt2 or a GeForce 3 Ti card, some games wouldn't run while other had TERRIBLE performance and graphical glitches. Used the 4x drivers and then everything was fine

I did a quick test. I installed the WDM drivers. I chose the sound blaster pro 2.0. I used the regular resolution, and I *think* that I used 11KHz in stereo (like I said, this was a quick test). Resolution has nothing to do I think. My computer crashed within the setup menu if I tried the sound test …

I never had any issue with the hotswap technique. (But I understand that you don't want to take the risk). I also know that you can't flash UV-roms with a motherboard. However doesn't the UV rom have the same pinout as flash eeprom ? I won't take the risk myself to erase the original rom if …
