RK05 Exerciser

This engineering specification describes the operation of the RK05 Exerciser, a tool used to issue basic commands to RK05 disk drives without requiring a CPU or drive controller. The guide covers the following areas:

• Controls and Indicators: Descriptions of the switches (Cylinder Address, Run, RTZ, FWD/REV, Function, Drive Selection, Write-related switches) and indicator lamps.
• Preliminary Set Up: Step-by-step procedures to connect the exerciser to an RK05 drive, including power supply connections.
• Positioner Exerciser Operation: Details on four modes of operation (Step, Alternate, Oscillate, and Random) to test disk positioning mechanics.
• Writer Exerciser Operation: Instructions for performing write and DC erase operations on the disk media.

The document also includes figures illustrating the front panel controls and flowcharts for the Positioner and Writer modules.
