     Hi all.  This posting might be considered a bit commercial, so if that 
offends you, hit "n" now...


You have been warned.  :-)

     Regarding Creative Microsystems Inc.'s Processor Accellerator:  I've
seen it, it exists, and I'm going to buy one.  I saw a demo the other day,
and was so impressed that I decided to dig into my hard disk fund to get one.

|Well..  I was intrigued by an ad in Info from CMI (Creative Microsystems Inc.)
|for a widget which supposedly substitutes for the 68000 which has a 14Mhz
|68000 on it and a 68881 socket so I called and got the literature.
|
|Claimed performance increase of 20% - 40%.  Advertised price is $149.95
|without the 68881 and $199.95 with it.  You probably aren't going to get
|any cheaper than this.

     Well...  I called CMI today to put in my order, and this is (from
memory) what they told me:  The $149.95 unit is the one with NO support for
the FPU, not even the glue chips or socket.  The $199.95 unit has the glue,
socket, and support software, but *NO* *FPU*.  :-(  The person I talked
to apologised for the badly worded ad, and said that the marketing guy was
"taking it in the shorts" for that gaffe.  Interestingly, their dealers
weren't interested in stocking the FPU-less model, only the more expensive
one.  So if you want one, I guess that's the spendy one you'll have to get,
and buy the MC68881 yourself.  

     There are two different models (other than the price differential, that
is).  One is for the A1000, the other for the A500/B2000.  The 1000 model
should be shipping this week, the 500/2000 model should probably ship some
time starting next week.  As far as I know, there isn't one for the A2000.

     A little technical info:  The board boots up at 7MHz.  They supply a
program to toggle the speed between 7 and 14 MHz.  There is also a program to
tell the system that it has an MC68881 installed.  The FPU runs off of its
own crystal, and may be faster than the system clock.  (The one I saw was a
16MHz model.)  Unfortunately, under v1.2 Amiga software, the system won't
automatically use the FPU.  That ability has to be compiled in.  Version 1.3
will have the new floating point library, which the Amiga will use if it
knows about the '881.  I don't know how many programs use both software and
hardware float routines, so I don't know how useful this gets under 1.2. 
Guess I'll find out when I get mine.

     ???  I assume David means the Acellerator.  The Kickstart Eliminator has
been shipping for a long time now.  The company has been around for a while,
and while it's small, seems solid enough.  Of course you should take that
judgement with a grain of salt...  Um, the entire salt cellar...  My business
acumen is virtually nil.  :-)

     Oh, and for those who want to know:  Yes, they will be installing v1.3
ROMs in their KickStart Eliminators, when C=A releases it.

    DISCLAIMER:  I have no financial or business connection with Creative
    Microsystems Incorporated, other than as a(n enthusiastic) customer.  My
    opinions in this matter are strictly my own, and in no way reflect the
    corporate views of Tektronix, Incorporated, its officers or subsidiaries,
    or of Creative Microsystems Inc.

     If this was overly commercial, I apologise.  It just seemed like the
perfect opportunity to let folks know about this, since the question was
asked, and I had just found out about the product.
