Apple Disk II controller and MicroSci A2 controller

A collection of simple (simplistic) tests for diagnosing a non-booting Disk II or A2 disk controller:

Monitor commands to test 6 of the 8 data latches in the 9334 chip
Monitor commands to load just one sector, then beep and break
Attach an LED to troubleshoot individual latches Q0 through Q3
Use a flashlight to "candle" circuit traces
Use wood or bamboo to scrape debris off the circuit board
