CDOSCOPY operates as a literal copy utility. The disks are
first logged in and then the program flow (and constants) are
adjusted to reflect the number of logical blocks on the disk
(its storage capability). With S/D S/S disks it operates on all
tracks, but with all others does not necessarily transfer the
boot loader.
It has not been tested with 5" disks and the code will need
minor mods to effect their copy. These mods should take 5 or 10
minutes.

Notes by Chuck Weingart:
To change to 5" disks do the following:
1. Change ITRK if desired, change LTRK to 39, the largest track.
2. Find the string "1BH" and change to "13H", the max sectors/
track + 1.
3. Find SDMAP, at the end of the program, and change the table
to an appropriate skew for 5". I suggest 1,6,11,16,3,8,13,18,
5,10,15,2,7,12,17,4,9,14
To change to a different memory capacity:
Find the string "-8000H" and change to a value that is within
the user area of your CDOS. 8000H is 32K, and will require at
least a 48K CDOS. If you dont know how much space you have in
your system, use the value given by CDOSGEN as the start of
CDOS, and round it downward at least to the nearest multiple
of 1000H.
