Seeking micro-dynamo software for the Apple //

[Ralph]

I am looking for disks (real disks or a disk image) for Micro-DYNAMO,
a simulation package for the Apple //.
The software was sometimes accompanied by a book, Introduction to
System Dynamics modeling with DYNAMO.

(A review of the software can be found on google books:

(ComputerWorld review)

My interest is historical curiousity, and interest in re-running old
models.  I have newer versions of system dynamics software, but the
syntax is different.  I want to run simulations written in the earlier
days of system dynamics modeling.  I have the Apple Pascal system.

Please let me know if you know of someone who has kept these disks.
