[Coco] F9DASM - 6800/6801/6802/6803/6808/6809 / 6301/6303/6309 Disassembler

[John W. Linville]

As Ed indicates, you can edit them out, or disassemble them and cut
them out of the resulting ASM source. One might even start with
an info file that identifies the 5-byte data blocks and helps to
identify the true ORG and start addresses. Or...

Yet another potential enhancement that could be made to the tool and
sent as a patch to github -- support for DECB binaries! Dragon DOS
binaries, and CAS files (same for CoCo, Dragon, and MC-10!) seem like
good candidates as well... :-)
