This post is Work in Progress! I will add the information I have.
Most of this information is from different internet forums, like this tread on CNCzone.com - What is a Terco?. The information provided here could be wrong or misleading. Use it on your own risk! Please help to complete and confirm. If you like to correct some of my terrible English please send me a private mail. I am searching a manual for this machine! Many people search for the manual of TERCO mills!
The system was sold in the late '70th / early '80th. The mill is driven by a large control unit. The controller is used for manual input of G-Codes, manual jog, loading and dumping programs to tape. The connection to the mills are 4 separate cables, X-Axis, Y-Axis, Z-Axis and Spindle Motor. The controller has some more connectors:
As this machine was build for education the controller was used to enter small G-Codes programs and is restricted to 100 lines of G-code. The programs could be dumped to tape and loaded from tape. I do not know if datasettes from '80th home computers are compatible.

Stepper Motors
As far as I know the stepper could work as bipolar steppers (with lower current) but I have not tested it! Please add a datasheet to this group, if you got it in better quality.
X-Axis
Motor Type . . . : Unipolar Hybrid Stepper Motor
Manufacturer . . : Sanyo Denki
Model . . . . : 103-807-7
. . . . : 1.8V / 4.8A - 1.8° / Step
Holding Torque . : 10.8 kg cm
Outside diameter : approx. 87mm (Nema 34?)
Connector . . . : ?
Datasheet . . . : Petra Christian University Library - robot-appendices.pdf Thanks to fräsili from Peters CNC Ecke (in German) for the hint.
Y-Axis
Same as X-Axis
Z-Axis
Motor Type . . . : Unipolar Hybrid Stepper Motor
Manufacturer . . : Sanyo Denki
Model . . . . : 103-815-2
. . . . : 2.5V / 4.6A - 1.8° / Step
Holding Torque . : 21.6 kg cm
Outside diameter : approx. 87mm (Nema 34?)
Connector . . . : ?
Datasheet . . . : Petra Christian University Library - robot-appendices.pdf Thanks to fräsili from Peters CNC Ecke (in German) for the hint.
Spindle
Spindle Taber . : Morse 1
Spindle Speeds . : 500 - 2500 rpm
Number of Speeds. : 9 (G-Codes S1 ... S9)
Connector . . . : ?
Spindle Motor
I do not know much about the motor. This thread on CNCzone.com might help. Thanks to fräsili from Peters CNC Ecke (in German) for the hint.
The spindle motor is my biggest problem in a project to retrofit this machine to use a modern CNC controller and LinuxCNC. Please share information about the motor if you have information. Would be great to hear from someone how has created a motor speed controller for it.
Motor Type . . : Thyristor controlled DC motor
Manufacturer . : ?
Model . . . . : ?
Power . . . . : 180W
Current . . . : (Probably) 1A ?
Voltage . . . : (Probably) 0 - 180V ?
Additional Equipment
Programming Terminal
I do not know how the programming terminal is connected to the controller and mill. A hole puncher, a printer and a plotter could be connected to the programming terminal.
Screen . . . . : 12 inches, green

The connection to the mills are 4 separate cables, X-Axis, Y-Axis, Z-Axis and Spindle Motor. The controller has some more connectors:
- round connector for datasette,
- female 25 pin SUB-D port labelled V24/RS232,
- unlabelled male 25 pin SUB-D connector. It is a robot interface (G-Codes M10, M11, M60)
- connector like a TV antenna.
