Secret Diagnostic Parameters

These parameters are accessed by pressing COMMAND-ENV1-ENV1 on any Original EPS, EPS 16-Plus, or ASR-10/88.

CALIBRATE KEYBOARD
Does the calibration of the keyboard that is run on bootup. Helpful if your calibration fails, and you want "another shot at it".

SOFTWARE INFORMATION
Tells you what RAM OS you are running (your boot disk), what ROM "BIOS" chip is your machine, and the keyboard version.

EXAMINE DOS STATUS
Contains read-only parameters DMAC ERROR, DMAC STATUS, DISK STATUS, DOS STATUS, FILE ERROR, AUX STATUS..

EXAMINE ANALOG INPUTS
These show the values that each analog input is set to. This is helpful, for example, of making sure your pitch wheel is set to dead center (64), or your pedal is transmitting any information. The values changes as the analog input is changed.

GPR MONITOR
GPR stands for General Purpose Registers. These are the registers in the Motorola 68K chip. There are 2 modes, READ and WRIT (write, of course). DO NOT USE THE WRIT function - it could be possible to damage preset data with the chip. The monitor shows what is running through the registers.

INSTRUCTION MONITOR
The notes regarding the GPR monitor apply here as well.

ESP TESTS
There are 3 tests, LOW VOLTAGE, HIGH VOLTAGE, and ESP RAM TEST. I have found none of these being harmful, although you can proceed at your own risk. All of them usually pass.
