Introduction

Entering the Monitor There are two methods to enter the program:

Program CTRL-ALT-INS - Press and hold the CTRL, ALT, and INS keys and then release them. A message similar to the following appears:

MFM-200 Monitor, version x.x
Memory size: xxxx

Enter '?' for help

The first line indicates the ROM version. The second line indicates how much memory is installed, including base and extended memory. The third line gives the syntax for the help command. The last line contains the Monitor prompt (->).

CTRL-ALT-ENTER - If the CTRL-ALT-INS key combination does not force the computer to enter the Monitor program, press and hold the CTRL, ALT, and ENTER keys, and then release them. The CPU register contents are displayed on the screen, followed by the Monitor prompt.

Note: In some cases the CPU can lock up, preventing access by either method. If this happens, turn off the computer, wait 20 seconds, then turn it back on. This clears the CPU and allows you to use the CTRL ALT-INS key combination.
