[Coco] Having fun with hacking HDB-DOS

[Kip Koon]

Hi Juan!
A very interesting add-on to the DRIVE command.  What is the default mode?
Would it be DRIVE LINE 0?  
I wonder how many DRIVE syntax add-ons and changes have been made over the
years since Disk Basic was first released by Tandy.  
Do you know if anyone has ever documented all the different Disk Basic rom
images created by everyone in the Coco Community over the years?  I have a
number of different Disk Basic roms myself so I for one would find the
article quite interesting.  Take care my friend.
Kip

No new functionality but a neat tweak. I added syntax to the DRIVE command
to select the I/O method (or "line"):

DRIVE LINE 0 <- 38kbps DW
DRIVE LINE 1 <- 57kbps DW
DRIVE LINE 2 <- Becker port

Also, I decided to give this concoction a reasonable-sounding name:
R+DOS-16. The 16 should be self-explanatory. R+ is the name of the
blog me and a bunch of others edit -- Retrocomputaria Plus.

The ROM:

The patch against the Toolshed repo:
