Ha, you're right Tormod. I was forgetting that.
You can tell I'm a stranger to the world of coding. : )

Steve, XRoar is developed on Linux :)

Hi Andrew,

As Steve mentions, if you want to emulate CoCo1/2 and Dragon, there is
nothing better than XRoar.

The best cross-assembler for 6809 is LWTOOLS. The most comprehensive C
cross-compiler for 6809 is gcc6809, however the easiest one for
developing for the CoCo is probably CMOC.

Since you are using Debian or Ubuntu, you are lucky and you can get
the latest releases of XRoar, LWTOOLS, CMOC, gcc6809 (and toolshed)
from this PPA: https://launchpad.net/~tormodvolden/+archive/ubuntu/m6809

lwasm --format=decb will generate a DECB file. This file you can load
directly in XRoar, e.g. on the command line when starting XRoar:
 xroar -load mydecb.bin
You can also add -type "EXEC" to the command line.

You can also make disk images with the "toolshed" decb command, but as
seen above it is not necessary to go via disk images.

XRoar, lwtools and toolshed are also available for MacOS and Windows.
gcc6809 (and probably CMOC) also for MacOS. gcc6809 and CMOC will
probably run fine on Windows 10 using the Linux packages and the new
Linux subsystem for Windows 10.
