Here is a nice little IBM 4-1 for sale or for trade... The keyboard itself is in great condition... I could probably use a little cleaning but other than that it works great... I have been using it on my workstation at work for the last couple of months so I know it works good....
The keyboard is a great size and the trackpoint is handy as hell! If you have any questions just let me know!
And YES! It does come with the dual PS2 cable!
