CPM disk factory

This will allow you to create 64 or 128MB disk images for use with for example an RC2014, or its emulator. The diskdefs file contains definitions for both.

Files found in content/? will be copied to the corresponding partition.

Some files found under content/pkg are created from the RC2014Z80 CPM IDE images, the contents processed with filepackage.py

Other disk targets (simh for example) are possible by adding them to the diskdefs.

dependencies

This bash script uses cpmtools and a few unixy tools like awk, dd. To create a bootable disk I've copied the bootblocks from the RC2014Z80 project images. I found that cpmtools work better with multi-partition disk images under linux than osx, YMMV. The script will build the image, but after that manually copying to anything but the a: disk won't work.

populating the disks

The directory content contains directories a-p for each partition. The scripts will copy the content of each directory to the corresponding partition

Keep in mind that the last partition is 2MB, h: for a 64MB and p: for a 128MB image.

The n: and o: disks will have some DOWNLOAD packages available

rc2014 emulator

the RC2014 emulator requires an IDE disk. I've created a disk image the the makedisk tool that comes with the RC2014 emulator source, copied the first 1k to the ideheader.1k file. To create the required IDE disk image, the script will concat the ide header and the CPM image.

NB: This is a hack. The IDE header is for a 540MB IDE disk, but the image is only 64/128MB. The emulator is happy enough with it, so it works for me :-)

usage

Put everything you want to appear on the image in the content/[a-p] directory. Alternatively you can remove a content/? directory and put a 8MB diskimage in place with the name '?.CPM'. The script will then use that disk image as partition (this is terrible UX, so kinda just like cp/m) Run the script, use dd or win32image to put the CPM128.img on a cfcard.

Or use the RC2014 emulator with the cfdisk.ide image:

rc2014 -s -r ~/dev/RC2014/ROMs/Factory/24886009.BIN -e 2 -p -i cfdisk.ide

bugs

• the content/[a-z] directories have a dot-file .git_placeholder. It's a hack for git. Consequently, the script will ignore dot-files. They would show up in CP/M as a file with only an extention.
• not a bug: script will overwrite anything with the name CPM128.img, CPM64.img and cfdisk.ide. It's a factory, just build it again.
• the download pkg format on the disk image is perhaps not the sma(ll|rt)est format, but it's convenient from this side of cp/m. It's there if you want to provision your cp/m machine over serial

TODO

• Maybe a script to create a content directory from an existing image, as kind of a backup.
• create zip archives instead of download pkg
• something something files in database something metapackage something install from database yada ready diskimage
