2 PS/2 keyboards possible?

[Friedrich W. H. K. <Fri...@ko...>]

Hello,

I recently started* my ambitions to set up a multiuser terminal, too, reusing 
a bunch of old computers, graphic cards, and whatever, hoping that at least 
some of the hardware got working driver :)

Reading through all the documentation I stumbled over 
http://www.ltn.lv/~aivils/eng-hw.html and wondered: 
Is it really possible to connect a PS/2 keyboard to the port usually given to 
a PS/2 mouse? That would be great, for a two user setup with some serial card 
plugged in one wouldn't even need any USB device. So did I read correctly? 
Does this work out of the box?

* Stopped at the moment at rebuilding different xorg source rpms for my SUSE 
10.0 which all tend to fail at the end, even unpatched #/

Regards
Friedrich

With 2.6.x kernels it works out of the box.

Although there are mainboards that handle this as an
error condition and stop booting waiting for you to
press F1. Booting continues after normally.

This works very well - you just described my setup.  Well, I used
to have two serial mice - one broke so I replaced it with USB.
Two ps/2 keyboards are trivial. If you get any trouble to sort out,
then it will likely be uncooperative video cards. 

As for "working out of the box", you have to set up your xorg.conf files
carefully.

Since no keyboard advances are possible since IBM made
their Model M keyboard, having reached perfection, I
have 2 of them from 1989 plugged into the keyboard
outlet and into the mouse outlet.

Then 2 optical mice into 2 USB ports.

This works with either Ruby or Faketty. But Faketty
beats Ruby hands down because textmode is so much
better on the AGP screen.

Great. Thank you all for your answers, that served as proof at least=20
heuristically :P

So having my fears of damaging something blown away I tried it out and, nic=
e,=20
am seeing it working here, too. :)

Having now succeded in patching the SUSE 10.0's xorg rpms with the=20
isolate-device patch and having cross compiled the faketty input handler (i=
s=20
at least insmod'able at the target) I am right now setting up the environme=

(reading, typing) and, well, let's see...

I had no problems using two PS/2 keyboards with ruby (along with an RS-232 
serial mouse and a USB mouse). In fact, even without ruby, Linux seems to 
work fine with a PS/2 keyboard plugged into the mouse port.
