Common JiffyDOS and BASIC commands I use often.
Display current drive’s directory
F1
or
@$
Change the drive you want to use
@#10
Where 10 = the ID#
View a drive’s partition table
@$ = P
View a directory’s files with time stamps
@$ = T
Change partitions
@CP2
(e.g.)
where “2” = the partition number
Load a program
%[name]
i.e. this is like, having typed Load “name”,8,1
Load a basic program
/*
i.e. this is like, having typed Load “*”,8
/
[place on any row with a program; don’t worry about any other text as it will load]
↑
this is just like “/“ for loading a program but it also runs it
Make a Directory
@MD:[name]
Enter a Directory
@CD:[name]
or
@CD:[name] [then hit F1]
Remove a Directory
@RD:[name]
Go to ROOT Directory
@CD/
Change current drive to next available
CONTROL D
Auto-starts first program on a disk
Shift RUN/STOP
Rename File Name
@R:[new name]=[old name]
Format Disk
@N:[name,AA]
Copy File
@C:[new file name]=[file to copy]
Scratch (Delete) File
@S:[file name]
———CMD HD SPECIFIC———
Note that HD TOOLS will lock up if the parallel cable is installed and active. Unplug it or disable it with the JiffyDOS command @P0 before running HD TOOLS. The parallel cable can be enabled again with @P1 after exiting HD TOOLS.
To learn the ROM version number of your HD, type:
CMD HD Series BOOT ROM
The CMD HD has a 27256 EPROM called the “BOOT ROM”. The latest known version of the BOOT ROM is 2.80. Earlier versions should be upgraded to 2.80 to ensure the drive has all the bug fixes. Hold down SWAP 8 and SWAP 9, momentarily press RESET, then release all buttons. This puts the drive into configuration mode where only the BOOT ROM is active and the drive responds to device number 30.
Show the BOOT ROM version with JiffyDOS:
@#30
@
73,CMD HD BOOTROM V2.80,00,00
Show the BOOT ROM version without JiffyDOS:
0 OPEN 15,30,15 : INPUT#15,A,B$,C,D : CLOSE 15 : PRINT B$
RUN
CMD HD BOOTROM V2.80
———BASIC COMMANDS———
Partition Listing
LOAD “$ = P”,[#ID]
Change Partitions
OPEN 15,10,15,”CP2”:CLOSE15
———SD2IEC + JIFFYDOS———
Mount a D64 file on an SD2IEC
OPEN1,8,15,"CD:MYIMAGE.D64":CLOSE1
@cd:filename.d64
Copy from one drive to another
1. CTRL-D to select source drive
2. "@Xn" to set destination (n=target drive ID)
3. "/$" to load directory
4. CTRL-A to select all files or use "LIST" and CTRL-W to select individual files
5. "RUN" to execute copy
If you have some common commands you use often that are missing, let me know and I'll consider adding them to this post.![:disk:]( "Save!")
