[comp.sys.apple] DOS for 400k drive?

ZAKAR@A.ISI.EDU (06/24/88)

I have a Mac 400k drive that I hooked to my Apple II+using Central Point
Software's disk controller.  Works fine with PRODOS but I'd like it to work
under DOS 3.3 also.  Somebody passed me a copy of AMDOS, but it only works
on 800k drives.  Does anybody have information on how I can obtain a
freeware or shareware (or whatever) version of DOS for 3.5 inch 400k disk
drives?

Thanks,
