Someone recently posted an Enhancer 2000 disk drive for sale and listed it
as 1541 compatible.  Anyone considering such a purchase should know that this
unit is NOT 100% compatible.  It is in the area of 95-98% combatible with
1541 oriented software.   I own an Enhancer 2000 and her's what I have found:

1) It is slower than a normal 1541 by several RPM's.  It is a full 20-30
   RPM's slower than my Excelerator plus drive.

2)  It will NOT run GEOS 2.0.  It probably has something to do with GEOS's
    copy protection scheme - calls to the drives's ROM and all.

3) It will run nearly any piece of commercial software created before 1988.
   It seems to run all games and programs written in BASIC just fine.

4) It has some trouble with the newest games - again...could it be due to
   copy protection schemes?

So...I have my own questions...
 The ROM is labelled as written by the Enhancer people.  I have forgotten
the actual statement and copywrite notice that I found through software.
My Excelerator has an actual Commodore ROM in it.  Does anyone know if I
can replace the stock ROM with a Commodore ROM (either 1541 or 1541II)?

I have not seen the Enhancer listed in any of the disk drive modifications
such as Jiffy DOS, etc.  Does anyone know if these modifications would work?

Any input as to why the Enhancer 2000 will not run GEOS 2.0; please post - the
discussion might spur on some interesting programming/application ideas.

BTW - Everytime I have called a shop or a software outlet and asked if a
product will work on the Enhancer, I get a groan on the other end of the line.
It seems that old timers remember the compatibility problems and say:
"Yeah, I remember that unit - you'll notice that the manufacturers are no
  longer in business!  Good thing , too!"

oops! I spelled compatibility wrong in the header!
