Stepper Motor Specs

Hi
I have been trying to chase down the specifications for a couple of
Japan Servo Stepper models. Their site only lists specs., for the latest
models. On their site they advertise a CD-ROM database but after 2
months of emailing them with no replies I have given up! Does anyone
know of a Web site that might be a repository for past motor specs?
The particular models I am interested in are:-
KP56KM2-028 (it is a frame 23 200 step unit with 12v rating. I
need to know the torque and max current)
KP8M2-003 (This is a frame 34 200 step unit with 14V
rating. I also need to know the torque and max current)
I have searched the stepper motor forum at eio.com and the data at
Simple Step to no avail.
Any pointers would be gratefully accepted.
TIA
