DOS 3.3 on a ProDOS hard drive

[thm1@ellis.uchicago.edu (Tom Metcalf)]

Are there any programs available currently which let one run DOS 3.3
and DOS 3.3 programs off a ProDOS hard drive? (This is on an enhanced
Apple ][e). (Not programs to read DOS 3.3 files and save them as
ProDOS--I already have programs to do that). I remember one being
advertised a few years ago (something like DOS Master??) but have lost
all references to it...
