A socket 7 board will have a ps/2 mouse port as well. In fact most have usb.

Take a good picture of the board. or give us a model number. myself or someone else should be able to point out where to plug things in.

and, asuming your USB keyboard & mice were works on system with ps/2 ports, using the converters (since i know some were not),
adding this one probably works.

Here are the specs of the board. It says there are two serial ports but the only one coming out of the back of the board is the aforementioned AT keyboard port.

Guess it's an Intel 430FX, since it does not have USB. Newer chipsets like 430HX, VX, TX already have USB ports, and in case of VX and TX, SDRAM support.
Considering PCI PS/2+USB cards, they do not need any kind of drivers for the PS/2 ports. Just for the USB, I think.

You need to get an adapter for serial if it is FX and it is AT form factor. Only ATX oem FX boards had ps/2 support.

Do you mean something like this? http://www.ebay.com/itm/PCI-to-2-Dual-COM-RS2 … =item4840e313d8

Problem is it doesn't mention dos or win 95 in its supported oses only 98se 🙁

You do not need one of those PCI RS232 adapters. Any socket 7 mobo already has them. If is AT, it has headers. If is ATX, it has'em on the back panel.
I still think a PS2-USB combo card is a good idea. I think I will order one.

Thanks filosaurus, it's an AT board so it has the headers. So how do I hook the headers up (like where can I buy one, haven't seen them on eBay). I might go with the usb + ps/2 card tho.

Nevermind, found and bought this: http://www.ebay.com/itm/310385753430?ssPageNa … 984.m1439.l2649

Thanks to everyone for all the help, it's been educational.

They're not as good an idea as they appear to be. Those things don't actually have real PS/2 ports on them. They use a USB->PS/2 bridge, same as the converter dongles (like these), except that it's mounted on a card instead of a cable. Which means that it won't work for low-level stuff (like getting into the BIOS) on older boards that don't have native USB support.

I haven't bought a soundcard yet, but the ISA Soundblasters I'm looking at will have a DB9 port (I'd planned to use that for a joystick tho)

Wouldn't that be a DA-15 port?

My socket 7 system doesn't have PS/2 or USB. But to be fair it's probably the cheapest motherboard intel made that could fit a pentium. I just use an old AT keyboard and a serial mouse. works fine for me.

It would probably best to just use a PCI USB card and a USB mouse for these Sytems. If you plan to run winnt, I find the 3rd party USB HID mouse driver to work fine, even on a 486.

If you're any good at soldering, you could see if the board has solder points for a mini-din connector. On my 486-PIO3, I removed the old AT connector and soldered the mouse and keyboard mini-din connectors in place. Everything was in place for the hardware to work (didn't need any resistors or anything).
