If somebody is nice enough to buy all 3, I'll be happy to buy 1 off him... if they are ps2 or can work on ps2.

looks like terminal keyboards, so no, not PS/2. will need to be converted.

Short answer = no.

A Teensy and Soarer's Converter ($20 + an hour at the soldering table) will make these usable on a modern computer via USB.

Terminal Keyboards are easy to get a hold of for me, and no they will not work with PS/2, Don't even waste a cent.

Even if you get a PS2 version, it may or may not work on your motherboard as newer boards don't always provide enough power.

Now that issue I haven't run into at all. IBM Model Ms with PS2 connections drain a little over 110mAhs, and with the ziotek ps/2 to USB converters, the power draw is fine for USB ports which give up to 500mAhs

The OP asked about it working on PS2, not USB.

The problem is that many modern PS2 ports no longer support 110mA, and neither do the usb to ps2 adapters. This is why you have to use special Ps2 to USB adapters.

From Clickykeyboards.com
"Online reports indicate that these vintage IBM keyboards pull up to 100x more current compared to modern keyboards (112 mA vs 1.2 mA)."
