- Proxy Statement This is Document outlining the exchange of the company to Jot Engineering gives interesting details about the number of this type of machine and cost etc…
- OZO Support Some ex OZO technicians that will repair and work on these machines, they have a history page images of the machines and, sell replacement parts, software.
- Servo Spindle Motor Driver Chip DataSheet link for the chip that controls the spindle motor drive electronics
- Anaheim Automation The people that make the stepper Motor Controller Module
- User Manual Link to a user manual that is very similar to the controller box in the OZO machine not the same one, however email to Anaheim yielded no return on the exact model number of the box thats in the machine, so far this is the best reference for the hookup.
- Stepper Motor A catalog from EADmotors Eastern Air Devices, list the stepper motor in the machine. model LA23DGK-23 in unipolar configuration (6 leads) (6.00 VDC) (1.76 amps) (3.40 ohms) (8.4 mH) (168 oz-inch) in bipolar configuration (8.50 VDC) (1.25 amps) (6.80 ohms) (33.4 mH) (210 oz-inch) Not sure right now the motors are in bipolar or unipolar configuration.
- 4N26 Opto-Isolator the chip I plan on using to isolate the computer parallel port from the machine controller. Mainly just because I have some.
- Parallel Port Link to the Hardware Book parallel port pinout page
- A Chart of the Pin Out of the Ozo Machine as I manage to trace out the existing connections
