Summary of EXORdisk II/III Operating System User's Guide, Second edition, 1979
(First edition was 1978), which describes:
M6800 Diskette Operating System (MDOS) or
M6809 Diskette Operating System (MDOS09).
Diskette operating system
Boot up
When you power up the EXORciser, the M6800 runs the EXbug
monitor ROM and the EXbug prompt is displayed on the terminal. To boot into
MDOS, you must jump to the diskette controller ROM by typing:
MAID E800;G
Drives
There can be up to four drives connected to the system, numbered :0 - :3.
Sign-on Message and command line prompt look like this:
MDOS 3.00 (M6800)
=
Upper case
Althought you can edit files with both upper and lower case
letters, commands must be in all uppercase. Lowercase letters are not
allowed in file names.
3. Command format:
NAME1 NAME2 [,] NAME3 [,] NAME4 ... [ ; OPTIONS ]
Each name is a file name. NAME1 is the command and the others are
file name arguments for the command. The comma separators between the
arguments are optional. The semicolon before the options is mandatory.
File names
File names in MDOS are up to eight characters with a two
character extension. The first character of both the name and extension
must be a letter. The others can be letters or numbers. Only uppercase
letters are valid for filenames.
Drive specifier
Each name can be post-fixed with a drive specifier as shown
in the following examples:
FOO:0 BAR:1 FRED.SA:2
Default drive is :0. There is no concept of "current drive" as with MS-DOS.
Special keys
DEL deletes the last character.
Ctrl-W pauses the output. Hit any other key to restart it.
Ctrl-X cancels the line.
Ctrl-D redisplays the line.
Break aborts a command in progress.
Device names
Devices may sometimes be used in place of file names:
- #LP
- Line printer
- #CN
- Console output
- #CP
- Console punch
- #UD
- User-defined device (for COPY command)
- #CR
- Console reader
- #HR
- EXORtape
