Sanyo "Step-Syn" Stepper Motors

Group:
Tonight I dug out of the barn, a 1980 IBM Printer (thing weighed a ton!)
and tore it apart. Came up with a couple of power supplies, various and
sundry boards, and two Sanyo Step-Syn Stepper motors.
The nameplates on each list the motors as:
Type 103-820-2
DC 4.5V
1.4A
2 degrees/step (that's what it says!)
They are approx 3-3/8" (85mm) dia. 2-1/2" deep (not including the shaft)
with a 3/8" (10mm) dia X 1-3/32" (28mm) long.
One of them has a belt pulley on the shaft that I can't seem to remove
but it is very close to the motor body.
Motor leads are as follows:
1-blk 2-wht 3-red 4-blue 5-red/wht 6-blue/wht
Here's my question: Any value to these things? I would like to build a
small (16"x24") sign router.
