[Coco] HDB-DOS and double sided drives

[David Ladd]

Henry,

Yes you can get access to the back side of the double sided floppy disk
from HDBDOS if you modify the table that holds the bit patters for the
drive select lines.

https://colorcomputerarchive.com/files/Documents/Books/Unravelled%20Series/disk-basic-unravelled.pdf
PDF Page # 70
Table label is:
LD89D
The address start is at $D89D

This also works with CoCoSDC-DOS as well. :D I use it often on the SDC :P
on double sided disk images LOL

Sincerely,
Dave
