The web link you provided in your OP, goes on to say, under System 
Compatibility:
"The client crashes upon connecting via a SNA•ps gateway when ran on 
PowerPC Macs,
[...]
The gateway software requires special hardware for the SNA network 
connection and is therefore limited to NuBus systems. [...] Testing of 
the gateway software on the first generation NuBus equipped PowerMacs 
also hasn’t been done, yet."

And under Pitfalls:
"Neither SNA•ps 5250, nor SNA•ps print can be used on PowerPC machines 
when connecting via a SNA•ps gateway. As soon as the connection is to 
be set, the client crashes with an illegal instruction error."

I cannot imagine there are many Nubus slotted Macs that can run Mac OS 
9. But, as the author also says, "untested".

It seems though that compatibility for running this software on PPC 
Macintosh, if it is going to work, has very specific requirements.

So, good luck with your tests, I hope the FPU emulator is of use, not 
only for this program, but for any others you might trial.
