Dragon Docker

This is a simple container for developing BASIC or assembler software on the Dragon 32. It contains the Xroar emulator, 6809 assembler, and a .bas->.cas converter.

It has only been tested on Linux.

Docker creation

First, you need to create a container which can be done by running the script:

./0-build.sh

WARNING: This also opens your xhost on local to accept graphic traffic from the container

Secondly, with a valid container run:

./1-run.sh

You will then be dropped into a (root) shell in the Docker container.

Doing Dragon stuff

There are a couple of sample progams in src which can be build, and automatically run under the emulator with:

./doasm.sh

for a simple 'clear screen' assembly program, held in src/asm/test. Pass a filename to this program to assembly other code. The resultant binary is written to out/src/asm/test/main.s.bin

./dobas.sh

to convert a plain text BASIC program into a CAS file, written to out/src/bas/test.cas.

And finally, run any existing .cas files with the wrapper script of:

./docas.sh

Because the container mounts a directory on the host machine, you can edit the source using whatever tools feel good, without having to install them into the container.

Ending the session

Remove the xhost access rights with

./2-end.sh
