I heard OS/2, early versions, have problems booting and installing with a " fast" CPU (anything beyond 386 or 486 won't work, without modifying the binary). I was wondering, what does "fast" mean here? I mean, there are 100MHz 486 CPU's, is that "too fast" for OS/2 1.1? I would love to know a little …

I think I will return the PSU, I noticed that when I connect the PSU to the power and press the power switch, the fan doesn't spin... And if my memory doesn't fail (it has been ages since I had to deal with old hardware) that is not a good sign :( I share a picture of the inner of the PSU just in …

@TheMobRules the seller tested the PSU and says it works. I will open the unit and take a look (and send a pic) to see if everything looks fine.

Yep @debs3759, I do have a multimeter! @The Serpent Rider, maybe a little more useful answer would be appreciated.

I recently got a cheap AT PSU for my old mobos, one of my motherboards, the GA-6BA, supports both ATX and AT PSU so I decided to try and connect it. If I remember correctly, the P8/P9 connectors have an order and the black connectors should be together in the middle (I followed this image, just in …

Thanks @Deksor, I think it is blurry because compression, I had to do that because the real image was too big and surpased the upload limit. Glad to help!

Thanks @aha2940 that actually answered my question!. Yeah, I already ordered a PS/2 keyboard, finding an International English AT keyboard sounds like too much effort ATM.

This is maybe a super basic question but I thought this will work: Old mobo only supports AT connectors for keyboard I only had a USB keyboard I have an AT to PS/2 converter I have a PS/2 to USB converter https://www.vogons.org/download/file.php?mode=view&id=96745 For my surprise it doesn't work... …

Wow, thanks @PC Hoarder Patrol for the diagrams, my mobo revision is 2.4 and now that I know I have to made the cables by myself it will be a lot easier (I guess) and a more entertaining project 😁

I am really getting crazy here, I recently got an old Gigabyte GA-6BA motherboard for a really good price, I tested it and it works like a charm! but I got a really "small" problem... I have no idea what connectors are needed for the PS/2 mouse port (the one with just 4 pins) :| I had been looking …

Nah @zyga64 I tried already patching the svga256 driver with vgapatch and it didn't work. I think I will have to stay with that low resolution in Windows 3.11, I really have NO idea what is happening... I am pretty sure that card is capable of supporting VESA 2.0 but for some reason I cannot find a …

Thanks again @matze79 but I think I gave up. I tried with SciTech drivers, 5x, 6x and 7... No luck neither. The MSDOS driver says no compatible SVGA display chip is found, when I try and run manually VBETEST in version 6.x I can see it can correctly display the color and patterns at 1024x768 and …

Thanks @matze79 but sadly it didn't work 🙁 I will try with one of the old Trident cards I have at home because the max I could do with the integrated Radeon R100 has been VGA and lower resolution. again, thanks

Any hints about this video card and support in Windows 3x or NT 3.x? I got one of those HP thin computers with a Crussoe CPU and I was thinking in trying it with old Windows (pre 95) on it (and of course some DOS stuff).

Thanks @darry! I was thinking about an old 4:3 ViewSonic17" LCD display, with DVI/VGA output, nothing that fancy.

I was wondering, is there anything that I should look for a LED monitor for a retro machine running MSDOS and Windows 3.x/9x? I am looking at a 17" inch LCD but I don't know if I have to check for specific refresh rate or V-Sync or something like that, can anyone give me a hint here? Thanks!
