Re: Radius IP - another thought

[Aram Fingal]

Sonnet sells  G3 upgrade cards for the PowerMac 7200 which plug into a 
PCI slot and use the Radius multiprocessing API.  They do not run in a 
virtual machine like RocketShare but behave more like RocketWare.  It's 
a little funky to work with because the motherboard processor still 
initiates every task (as in RocketWare).  Also, like a Radius Rocket, 
it has RAM sockets right on the card.  RAM appears as one continuous 
block including what is on both the motherboard and the card but tasks 
work much faster when they use only the RAM on the card.  You will 
sometimes see things suddenly slow way down as the software needs a 
little more RAM and goes to the motherboard for it.

If you're thinking of messing around with the source for RocketWare and 
RocketShare, you may want to consider seeing if you can get them to 
work with the Sonnet PCI upgrade cards.  You can buy them at 
Macsales.com.  I think they will work with other PCI Mac models but the 
7200 is the one where it's most worthwhile because there's no other way 
to upgrade them.  It might be interesting, however, to have a hardware 
backed virtual machine running on newer machines, perhaps even under 
Mac OS X.

Does anyone know who currently owns the intellectual property rights 
for the Rockets?  I'd like to know so I can contact them and see if 
they'd be willing to give up tech documentation and/or source for 
RocketWare and RocketShare.
