If you are just getting started in retro-computing or even if you are a longtime guru, this software combination of both ProDOS 1.1.1 and DOS 3.3 has you covered.  It is a must-have item to add to your collection of useful tools.  

This disk differs from the "Apple II ProDOS and DOS 3.3 System Master 5.25” 2-in-1 Floppy Disk" in that this ProDOS User's Disk doesn't require a 65C02 CPU and thus can be used on a non-enhanced Apple IIe, etc.

This is a 2-Disk Combo in 1 Diskette:

You will receive: (1) One 5 1/4" Floppy Disk:  

Side A (bootable):  Apple II ProDOS 1.1.1 User's Diskette (Sep '84).  This is the 1983-84 version released for the Apple II series of computers.  This will come with a ProDOS User's Disk Quick Reference Sheet.

Side B (bootable):  Apple II DOS 3.3 System Master.  This is the 1983 version released for the Apple II series of computers.  Platform: Apple II, II+, IIe with at least 48Kb RAM

The is not a cheap, no-name brand but a new, original, 3M diskette and is tested and working.  I'm reducing my collection of diskettes and will have more and different titles available.
