Here's a bit more on the 1571/1541 compatibility question -

From the April '86 issue of the COMPUTE!'S GAZETTE magazine, here's
a blurb for a new speed loader for the C128 using either your old 1541
or new 1571 disk drives:

	"...Access Software introduced the Mach 128 cartridge, a fast-load
	and DOS enhancement package for either the 1541 or 1571 disk
	drive.  Program loads are [claimed to be - Bubba] up to 700
	percent faster with the 1541, and 'burst speed' loads are possible
	with the 1571.  Features include a reset switch for warm starts
	and a switch for selecting 128 or 64 mode.  Also included are
	short-hand DOS commands, 40- and 80-column screen dumps, and DISK
	ORGANIZER, a disk based utility for cataloging and organizing disk
	libraries.  Suggested retail price is $49.95."

In the February '86 issue of ?SYNTAX (the monthly newsletter of CHUG - the
Commodore Houston Users Group), Thomas Gumm Sr writes:

	"Contrary to popular belief the 1571 is not totally compatible with
	the 1541 so you will need to keep your old drive if you run
	commercially protected software.  One way around the problem is to
	copy your software from the 1541 to your new 1571 using a 2-drive
	copy program such as COPY-II.  If you use this technique, make sure
	to use the C-64 version of the copy program rather than the C-128
	version.  Many of the programs coming on the market today can be
	used in both C-64 and C-128 machines and therefore must be stored
	on a single-sided disk so they can be read by a 1541 or compatible
	drive."

I think the last statement refers to a need to store programs on a disk that
has been formatted in 1541 mode on one side using your 1571, not necessarily
using a single sided disk only.

Hope this helps you with your decision Alan, and I hope it helps anyone else
interested in the purchase of the new Commodore equipment.
