I don't suppose anyone has a copy of PC-DOS 3.3
they'd be willing to
 part with, or make disk images for me?  I have to restore an application
 on a PS/2 model 30 that requires it, and we've lost the disks (probably
 about 10 years ago...) 
Unless there is specific reason not to, I'd recommend using MS-DOS 3.31
instead.  It takes care of the 32M hard drive partition issue.
