Some actual results: I had to send the Minix disks over UUCP (*gasp* *gag*)
to get them to the target system (a Fortune 32:16 with no AT-compatible
floppies), and used "compress -b15" to save line costs (-b15 gives ALMOST
as good a compression as the default -b16, at half the memory cost). The
results were encouraging (and useful to my phone bill). Each of the
original Minix distribution -AT floppies were 1.2Mbytes. The compressed
versions were:

	-rw-rw-rw- 1 uucp      73082 Jan 31 05:41 minix.1.Z
	-rw-rw-rw- 1 uucp      28803 Jan 31 05:46 minix.2.Z
	-rw-rw-rw- 1 uucp     502798 Jan 31 07:04 minix.3.Z
	-rw-rw-rw- 1 uucp     566196 Jan 31 17:50 minix.4.Z
	-rw-rw-rw- 1 uucp     616796 Jan 31 16:20 minix.5.Z
