There probably is no good solution to this problem.  The number of different
ROMs means that a developer has a difficult time supporting all the
machines.  Here are some thigns to consider.

First, System 2.0 is recommended only for machines with 128K of RAM.  It
seems foolish to configure a product for this machine, when it causes
problems for the vast majority of users with 512K or more.  The solution
here might be to state that your program only runs on 512K machines and
above.  Such a statement doesn't exclude many users.

The recommended configuration for all other machines is System 3.2 or later.
(This is true even for 512K machines with old ROMs.)  LSC programs will work
fine on this System.

If you expect a user to boot off your diskette and start working, then the
only way to can cater to every machine is to ship the latest System file.
The latest System file has the ROM bug fixes for every machine.

Note that the latest System (4.2) will work fine on 512K machines with 64K
or 128K ROMs.  (I admit that I haven't tried this, but System 4.1 worked.)
The size of the patches, however, reduces the amount of working RAM, so it
is not recommended by Apple.
