Re: PPC incompatible software

FYI, that's my Wiki and I have written that text myself. :-)

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."

Yes. I think the text shows that there is a distinction between client and
server. The server (gateway) runs fine. I have not yet tested the gateway on a
NuBus PPC machine, because it runs good enough on the Quadra 700 I've picked
as gateway machine. NuBus is mandatory because my sole possibility for network
connection to AS/400 is the Token Ring Card as described in the article.

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".

Please don't confuse client (e. g. the 5250 terminal emulator) and gateway
software. The gateway is a protocol converter/encapsulator for the IBM SNA
protocol.

The gateway software needs "special" NuBus hardware as pointed out in the Wiki
article, and thus requires a Mac II class machine.

The client needs any Mac starting with a Mac Plus, and running System 7.

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

Which software? The gateway? Or the client?

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.

Thanks! As said, this is the first application I've encountered in years which
crashes on PPC but runs fine on the latest 68k hardware.
