  I have one, it's not IBM but third-party. We used
it to test XT's, I'll
 make you a image. It is 64k but I'll check if it's readable. And I
 should have the manual some where, but it's a very simple user
 interface. And it's does test the hardware.  
I don't know if mine is the same as Rik's, but I do have the Landmark 
"Professional PC Diagnostics" kit that comes with ROMs for both the 
XT and AT.  I'll be happy to send an image along if you think it 
would help.

Cheers,
Chuck
