RE: Sparc IPX

I just spoke with RAVE and they confirmed what I thought.  The original
25mhz Sparc chip in the IPC was produced by Weitek and is not upgradeable as
far as they know.  The Weitek chip they have is for IPX and SS2 only and
will not work in the IPC. (However, being the cynic that I am, I can
envision there being a hardware hack to make them work in the IPC boxes
since IPCs are PGA - something like a daughter board setup. If someone has a
Weitek IPX upgrade chip they'd like to send me to test I'll be happy to try
and make it work.;-)

They (www.rave.com) also only have 40 of the upgrade chips in stock so you
might want to get one now if you have an IPX to upgrade.

If anyone has more information please post it as there are a lot of IPCs out
there that could benefit from a mhz upgrade.

I just saw a few IPC's with Weitek upgrades in them at a computer show.  I
have no idea if the IPX versions will work (probably not), but at least they
were out there at one time.
