     I would like to know if anyone has  used  these disk drives with the
C64. I have found that these drives appear to  be an answer to the faulty 
1541.  This drive uses an optical sensor to  detect the  last  track, not
a solid object as on the 1541.  The drive  also  formats  the  disk in  a
shorter  time  than the  1541.  From  what  I have seen this is the drive
for me but  I  would like to hear from some other users!

     Is this a  great  drive  or  is it only a small step up on the 1541?
Are there any problems with these disk drives,  the MSD SD1 or SD2,  like
the  @  troubles, head  alignment  problems, and  over  heating  problems
associated with the 1541?

     For me the  MSD SD2  disk drives  appears to be a good solution.  My
only draw back is the price, $550.00 to $700.00. The cheapest price being 
from  COMPUTER MAIL ORDER   ph. 800-648-331 for the west and 800-233-8950
for the east.  The highest  price  was  found  at  Sunnyvale  Electronics
located on Murphy Street in Sunnyvale.  All of your comments are welcomed
and appreciated.

* The MSD Disk Drives do have some major problems. First, as if it where
possible, the MSD is SLOWER than the 1541!! (calling the 1541 %100, the
MSD comes in at %91)
* The MSD does not work with a lot of the avalible software. If you plan
to run software that you have purchaced you will need a 1541.
* The disk speed up products that are avalible for the 1541 (like 1541 Flash!)
are not avalible for the MSD.

  Other than that the MSD drives are fairly well built, and reliable.

While i will agree that the load speed of an MSD drive is
slightly (and i do mean slightly) slower than a 1541 and some
commercial software wont load, the MSD is a VASTLY SUPERIOR
drive in EVERY other way.  In case anyone thinks i am prejudiced,
I happen to own both a 1541 and an MSD SD2.  I use the 1541
and the EPYX fastload (sorry Bryce) cartridge to load
commercial programs.  That is about all it does.  I cannot
remember the last time it wrote to a disk.  My MSD formats
my disks (approx 10 seconds) does my backups (approx 2 minutes for
an entire disk), is used to move files around, and works real nice
with my terminal programs and my assembler and my word
processor and my spreadsheet and my database management
programs and my ......
oh well you get the message.

In all this use it has not even burped once.

Now as far as using the speed up enhancements you have to give
the 1541 the edge.  But I and probably everyone else who
owns an MSD would be eternally grateful (not to mention willing
to part with some cash) for a speedup goodie that works on
the MSD.

It is my opinion that people who have been willing to spend the
money for the MSD would probably be very receptive to a product
that would enhance their investment.

Are you listening Bryce?

By the way if anyone knows about such a product that works on the
MSD please let me know where the line starts to buy one.

  If you connect a MSD single or MSD dual with the provided serial cable
it runs a only %91 of the speed of the 1541 disk drive. That is SLOWER
than the 1541. If you use a IEEE-488 interface (add $150-$200 to the cost)
you will get a %150-%200 loading speed improvement. Most IEEE interfaces
are VERY incompatible with software. There are only two that I know of
that are truly compatible... The Buscard II ($125 + $50 for a IEEE cable from
Batteries Included) and MSD Flash (about $90 from Skyles Electric Works,
comes with cable at no extra cost). The buscard is %151 of the speed of
the 1541. MSD Flash is %309 of the speed of a 1541. My recomendations for
a disk drive are::: get a 1541 and modify it so that it will NOT overheat
(If there is enough intrest I will post info on how to do this). Then,
if its slow speed bothers you invest in a disk speedup product like
(heh, heh) 1541 Flash!.
	What you have is a drive that is as Fast as a much more expensive
	MSD system, and compatible with all the software avalible, which 
	the MSD is not.
