I would avoid usb mouses as much as I can All my systems use m590 with logi dongle as standard issue via nec 2.0. otherwise it's recommended sticking to intellimouse optical usb 1.1A for compatibility USB Mouses are nice and convenient but they tend to have a higher performance impact on old …

Well, I have tried to play doom under windows 98 using COM4 with Infrared, but it doesn't seems to do anything when I select the serial connectivity. So in short, is it possible to play Doom under IrDA? or even other ms-dos games? ( So far the only games that I managed to play with infrared were …

Old to the party but Vooodoo 3 works quite well with a Pentium MMX 233, it's a great card for DOS games and also early 3D games. ofc it's a card that has more power to deliver with strong cards, but the drivers are enough optimised to allow it to run just fine on old Pentium MMX machines (and never …

I dont understand the picture at all :( USB 2.0 has HUGE impact on performance of lower end systems, and judging by 10-16 fps you are running something socket7 https://www.vogons.org/viewtopic.php?f=46&t=39172 USB 1 is better, but still bad I have tested it on a laptop. About the Graph sorry for …

on old systems, I feel like benchmark numbers kinda cheat to the reality of how the game plays, so I have decided to create a benchmark running Quake 2 on the lowest settings to compare the performance impact of not interacting at all with the system with interacting with it while running the …

Do you guys think such product could exist? Here are the imaginary specs: - PCMCIA board that requires zoomed video support in order to render on the main display (so it works as a voodoo 1 or 2) - Voodoo 2 or 1 specs. - 16MB of video ram. - 3D Only. despite having an inferior performance to a PCI …

Hi @ibm5155. I just got one of these. Can you describe to me the steps you took to get to the hard drive? I don't want to break anything along the way so any advice and steps you can give would be much appreciated! Replacing the hard drive will be tricky since it's on the opposite side of the …

I did the same thing with this : I could never fix it.... (lack of knowledge to find fault). I suspected it was something simple since the laptop was working with battery despite not working on AC and i found out the battery circuit is connected to the AC one, a multimeter deffo would help to test …

I Accidentally plugged a 20v AC on it and it stopped working, luckily, only a fuse went bad, glad the board has a description on the type of the fuse (FO 32v 2.5A). doing direct contact on the fuse made machine to boot so now it's just a mater of trying to find a new fuse. By the way, I managed to …

Sorry for the resurrect, but on the topic, I noticed that Logitech G703 freezes the OS when moving the mouse and after a few miliseconds once stopped it seems to unblock the os. I also noticed it tends to run smoother if you use the wired usb option instead of the wireless one (perhaps it does some …

There is atleast one capture card that support ZV, the Margi Capture-to-Go, it also has svideo input. Most capture cards don't support ZV, and only had composite video input, like Nogatech, Iodata, Ratoc, IBM. What are the specs of the laptop? IBM Thinkpad 235 Pentium MMX233, 96MB Ram, C&T F655555 …

It's a tricky question and I am failing to search for it, so here's the questions. Do you guys know any PCMCIA card that has ZV support and preferably FM Radio tuning? I am aware that Analogue TV tuning is kinda dead nowadays but if the board comes with composite input it'll be a big plus.

I was wondering if it would be possible to use an old laptop with ZV as an external monitor. I am aware the resolution is kinda low but it would be a perfect use case for me if possible. So far the only options I saw were pcmcia cards that capture TV/composite signals but those seems kinda low res ( …
