[comp.sys.cbm] 1571 disk drive alignment questions...

lishka@uwslh.UUCP (06/02/87)

A long time ago, when I was a younger lad, I bought my c64, and soon after
I aquired a 1541 disk drive.  However, the heads used to go out of alignment
monthly, and the second time I brought it in to be realigned the kind 
repairman, sensing my youthful ignorance, made a permanent modification which
kept the heads from going out of alignment for ever more (and WOW! did that
set screw he drove into the collar ever do the trick!).

From what I had heard of the new 1541 (NOT 1541c) drives, they are constructed
differently so that the heads won't go out of alignment.  The same thing goes
with the 1571 drive.  And thus to my question:

	I recently read an add for a place that performs Mail Order Repairs
on c64's, c128's, 1541', and 1571's.  One of the repairs they listed was
something like 'Permanent alignment fix for 1541 AND 1571.'  Now wait a  
minute...I thought the 1571's were not supposed to need a permanent modification
because they were constructed like the newer 1541's (not 1541c's) to insure
that the heads would not become misaligned like the old 1541's.  Furthermore,
my brother has a 1571, and has never had any problems (but then again he
isn't a real programmer; he just plays a lot of games).  So what is the real
story behind the new 1571's and 1541's?

I am interested mainly because I am considering aquiring a c128 and 1571, but
if the drive is going to go out of alignment, I would rather stick with my old
permanently modified 1541 and c64.
