DOS 3.3 Emulation - With Multiple Volumes

[A2Aviator <a2aviator@gmail.com>]

I've not paid that close attention to the various DOS 3.3 emulation
solutions, but what I'm needing to do is emulate a DOS 3.3 environment
like you would find on a Corvus or Sider, or well, most any DOS 3.3
hard drive for that matter.

Virtual II does a DOS 3.3 disk from a folder of files, but .. I need
70 volumes to maintain compatibility with an existing software
package.

.. sadly, the thing is TASC compiled, so I can't do changes or convert
it to ProDOS.
