stupid newbie question, DOS, hard drives..

[Jerry Leach <atman@imt.net>]

Im using Virtual ][, and boy howdie what a blast from the past.  I was a 
real apple // wiz 25 years ago, now I can't figure out how to do 
anything.  I just figured out CAT.  But I just realized while posting 
this that I don't have any DOS disks.  I've been looking on the 
Asimov.apple ftp site, but I'm not sure where to start.  If I remember 
correctly, what I'm used to is MSDOS-5.0.  I've seen ProDOS pop up in my 
browsings but I can't remember what that is.  I've also used Novel DOS, 
can't remember what version.

I could swear the old //c I had booted right up into ms-dos.  Or is that 
the ProDOS I'm thinking of.  Dang, I used to be so good with the apple 
now I'm so confused.
