Has anyone out there got any experience with adding an ethernet interface to
a Mac IIsi?  I've got a IIsi 5/80 with Nubus/FPU adapter.  Asante tells me
that putting their standard Nubus board in is not recommended.  They didn't
seem sure it would fit (how could Apple make a machine with Nubus support
in which cards don't fit?  Isn't there a standard form factor here?!).  Also
said there might be performance problems given that the Nubus cards are meant
for 16 Mhz machines and the IIsi is 20 Mhz.  I don't understand that either,
as there are plenty of Nubus Macs that aren't 16 Mhz.

Asante recommends throwing out my Nubus adapter and using their new product
which fits into an si with no adapter or with the 030 Direct Slot adapter.
Needless to say, I'm not too excited about throwing out the Nubus adapter
I paid $150 for.  I bought it because I needed the FPU right from the start
and made the (probably wrong) decision that Nubus would be more useful that
030 Direct.

Asante also recommends using an adapter card from PSI if I need the FPU.
Well, that's fine too, and the new PSI card sounds neat (socketed FPU,
optional 64 Kb cache) but I already own an FPU.  They tell me the Apple
FPU is soldered in, so reusing it with the PSI adapter sounds tough.

Anyway, enough of that.  What are you people doing to get ethernet directly
onto IIsi machines?  Any real experience with a Nubus card?  I'm aware of
power problems with overspec'ed Nubus cards, particularly some 24-bit color
cards.  An ethernet interface ought to be well within 13.3 watts, however.

Along similar lines, has anyone any experience with Apple's new Ethernet NB
adapter?  Does Apple support it for a IIsi with Nubus adapter?

Thanks in advance for any advice.
