I need the net's collective expertise/experience about a few
questions.  Question 1:  I own an Apple //e (enhanced), RamWorks
III (1 meg), Apple floppy drives (2), and a Laser UDC and 3.5
drive.  I am about to get a second 3.5 drive.  I have had no
problems with my drive so I am considering getting another Laser
3.5, but I want to make sure I don't overlook any other options
which may exist.  The Applied Engineering 3.5 (with possible
expansion to 1.44M) is an attractive possibility but I don't know
whether it will work off the Laser UDC (or what one would use to
initialize a disk to allow access to the added space).  Similarly,
the AMR 3.5 is a possibility, but can it work with the UDC?  What
degree of compatibility/interworkability is there between the
three (Laser, AE, AMR) vendors' controller cards and 3.5 drives?

A second question:  Has anyone successfully disassembled the code
on a controller card which has more than $100 bytes of code?  The
convention cards use to turn off other slot ROM space is to hit
$CFFF, but I have yet to figure out a way to examine any ROM space
on a card above $CsFF.  Any help on this would be appreciated.  I
don't want to do anything to the code in the ROM space beyond
understanding what it is doing.  (This same curiosity drove me to
disassemble ProDOS V1.6 thru V1.9 and Basic.System V1.2 thru
V1.4.1.)

Last question:  My AppleWorks 3.0 will not format a 3.5 disk using
the Laser UDC/3.5 combination.  It just ejects the disk and
mutters about the disk being write protected (even though it
isn't).  Are there any clues about what is happening or any
patches to fix this annoying shortcoming?

In the interest of brevity, I won't bore you with my outrage at
Copy II+ V9.0's not being able to compare files on the same 3.5
disk, or even different disks with different volume names - what a
pain!  (This seems to be a function of version of 'util.system' -
some will, some won't work.)

(Matt D. @ Apple: I have a question about what looks like a bug in
ProDOS (P8).  If you can e-mail me an address of the form
"name!name!..." I will correspond directly about this.  No sense
cluttering up the net with this.  I am at "...!att!ihlpe!welsh".)
