Okay.  I didn't really expect to get away with 80 track storage, but I
thought it was worth checking out for these reasons:
1) Really understanding the har & firmware, as for writing own special
disk drivers
2) Obvious utility in cracking protection schemes
3) Aid in salvaging data from a disk written on another drive that was
way out of alignment (by more than 1/4 track); you could get closer to the
data using the in-between positions.

	Companies that sell copy-protected software without backup copies
should be stoned to death.  We all gather around them with our rocks;
the Coco owner who has never accepted or given copyrighted pirate software
gets the 1st throw.  Sounds like a dull afternoon.	mike k

BTW, if you are interested in using REAL 80tk drives with CoCo,
it works just fine.  I have two double-sided 80tk drives, and one
40tk drive running OS9, and it is truly wonderful to have a large
/d0/cmds area (UNIX hackers, read "/bin).

What's more, an 80tk drive is not substantially more expensive than
a 40tk drive.  One DS/DD 40tk drive with power supply and case will
set you back about $300 (I got mine at Software Support in Framingham,
MA.)  This is no more expensive than the suggested list price of the
grossly inferior Radio Shack 35tk single-sided drive.
