Greetings!
|
|
|
|
This is a utility that allows CP/M disk images to be manipulated under
|
|
Unix. It supports disk images in either the standard 8" SSSD format or
|
|
the P112 3.5" format. Disk images can be examined and files imported and
|
|
exported from them.
|
|
|
|
The source is a slightly hacked over copy of CP/M-68K which has
|
|
been worked over to allow compilation using GCC, to wit:
|
|
|
|
- A handful of typecasts have been dropped in.
|
|
- An assumption that an int is 16 bits has been fixed.
|
|
- An assumption that chars are signed has been fixed.
|
|
- The file diverge.h renames all of the globals to ensure they
|
|
don't collide with operating system globals.
|
|
- I changed the way the BDOS communicates with the BIOS; see
|
|
biosdef.h
|
|
- There are probably a couple of other minor changes I made that
|
|
I've forgotten (perhaps renaming a routine or two before I
|
|
decided to make diverge.h).
|
|
- A BIOS that allows the program to be run under Unix.
|
|
|
|
I've also added a couple of built-in commands:
|
|
|
|
- EXIT causes CP/M-68K to exit, returning to the host operating
|
|
system.
|
|
- IMPORT copies a file from the current directory of the host
|
|
operating system into the disk image.
|
|
- EXPORT copies a file from the disk image into the current
|
|
directory of the host operating system.
|
|
|
|
IMPORT and EXPORT do not accept wildcards. This is just a quickie hack
|
|
that turned out to be useful, not a snazzy disk image manipulation
|
|
program.
|
|
|
|
To build the program, execute make. This results in an executable called
|
|
exchange. The command-line syntax is:
|
|
|
|
exchange [-p112] file.img
|
|
|
|
-p112 This option tells the file to use the P112 3.5" disk format
|
|
for the image. By default, the the standard 8" SSSD format is
|
|
used.
|
|
|
|
file.img is the name of the disk image that should be used.
|
|
|
|
In this example, I copy the file BDOS.LST from an 8" SSSD image
|
|
containing CP/M 1.4 sources (obtained from http://cpm.z80.de/) to user 1
|
|
of the P112 boot disk image (obtained from
|
|
http://members.iinet.net.au/~daveb/p112/p112.html):
