Re: PPC incompatible software

That one has neither an FPU, nor an MMU. But maybe the emulator
code uses a gestalt call to know what kind of machine it's running
on, and dynamically branches to differently optimized code? On the
other hand, we're talking about a terminal emulator.

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.
