I am in serious need of replacing my 5.25" disk drives, but am a little
confused over the various kinds of drives offered for replacement.

My current 5.25" drives are a pair of 1978-vintage Apple Disk ][s.
What I would like to do is change my controller to the new style Apple
5.25" controller (DB-19 connector) when I get new drives so that I
won't have hard cables hanging out of the back of my //e.

My problem stems from all the different types of Apple-compatible 5.25"
drives I see available (especially mail-order houses).

Would someone please clarify the following desciptions of various 5.25"
disk drives that I see in ads and comment on the assumptions I have
made about them?

From a Programs Plus advertisement:

AMR:  A.5 Half-Height (][+ & //e)     ;I assume 20-pin header conn.

      A.5C 1/2-Height (//c)           ;Sounds like DB-19, but can it
				      ;have a 2nd drive attached?

      A5 D 1/2-Height (][gs daisychain)  ; I have no idea what
					 ; this means

Apple:  Apple 5.25 Drive (//e, gs, C+)  ;I presume that it uses the
					;DB-19.  As it is the only
					;one listed, it seems that
					;one drive fits all.

Also, the LASER drives:
  5.25 LASER/Apple //c    ;DB-19, I presume? Support 2nd drive?

  5.25 LASER/Apple //e	  ;20-pin header?

  5.25 LASER Daisy chain  ;Please explain

I assume that all non-Apple drives (except AE) support 40 tracks.
Basically, it comes down to:

"Which of these drives types would I be able to use on a //e with the
DB-19-style 5.25" disk controller?"

Please do not make recommendations based on the _brand_ but only on
the desciptions given with the drive.

Thanks for the help.

PS  I know what 'daisychain' means, but how does that relate to differences
in 5.25" drives for Apple //e vs ][gs?
