Hey so I recently became the new owner of an IBM Model M from 1995.
The issue is that the keyboard has a "8P5C (RJ-45)" out and I cannot use this.
Can anyone point me in the right direction to convert this to a ps/2 or USB out
whichever would be easier.
Thanks :)

I believe Soarer's converter might be able to help, if you're willing to get your hands a little dirty. http://geekhack.org/index.php?topic=17458.0

Hey thanks for the reply, I actually saw this earlier and was considering it. I guess that's the best way to go unless I could just rewire the connections to a ps/2 without having to modify the actual keyboard, only the cable
:)

I think the problem is most Terminal Model M's with the RJ45 connector send their output in Mode 3, which is why Soarer's converter is usually needed.
What's the P/N ?

You can come close to it. But you need a donor board to provide the PS/2 Set2 controller. A circa '95 3151 uses the same matrix as an M, so you can do a straight controller swap. But, like I said, needs a donor board. (Or a Unicomp controller, that'll also work.)

I'll get the part number when I get back to my house
Is it possible to use the existing rj45 connect with my computer?

Nope. Either that or controller swap. It is not a PS/2 keyboard.

Most likely it is a PS/2 keyboard and will work on PS/2 after cable swap.
There is a wiki article showing how to wire a PS/2 cable to these keyboards and linking to modified Windows driver which supports them.
Using them in Linux currently requires kernel recompilation with simple patch I've posted somewhere on this forum.
