3.5" drive(s) with //e - how?

[lemenst@fhsmtp.fh.trw.com (Thomas LeMense)]

Hello, all:

Since I was dragged kicking and screaming away from my ][+ in 1986, I
sort of lost track of all the nifty stuff that became available after
this time.  I have recently acquired a pair of enhanced //e's with
5.25" drives, and would like to use them again, etc..

I see a lot of software (particuarly the Eamon stuff, yay!) is
available on 3.5" disk -- where do I find 3.5" drives for an enhanced
//e?  What are they called?  (e.g.; duodisk = 2 x 5.25" drives, etc.)
Can I use some of the DD or HD floppy disks that I had once used with
my wintel box?

Thanks in advance for the help!
