7The monitor/boot ROM's (mpu-a-rom.hex and mpu-b-rom.hex) are full featured
8monitor programs. They first check if there is a disk in drive A:. If a disk
9is present the boot code loads the first sector and executes it, which will
10boot the operating system on the disk.
11
12If there is no file disks/drivea.dsk present, the programs loop on all
13possible input ports. Type a space character in the terminal window to get
14at the prompt.

16For the MPU-A ROM:
17IMSAI IEEE MONITOR    VERS 1.0
18?
19
20For the MPU-B ROM:
21IMSAI MPU-B MONITOR    VERS 1.3
22?
23
24The monitor has lots of commands, B will try to boot from disk, D dumps memory
25and so on. With R 0 1 it will read track 0 sector 1 into memory. The W command
26writes a sector to the disk! Become familar with this before trying,
27because writing some random bytes to the boot disk will make it unusable.
28The manual for MPU-B has a detailed description of all monitor commands.
29For booting both version will work, the monitor commands might have
30differences.
