The 2vx has its cpu, fpu, and cache running at 32mhz, and everything
else running at 16mhz.  Presumably those three units are connected to
each other so that they communicate at full speed, or it would be a
huge speed hose every time you sin() or ask for anything out of
memory.  But any time you go off that 32mhz section, the entire unit
has to slow down to 16mhz, and starts throwing wait states.  Every
time you get something out of main memory.  Every time you send a
pixel to video (I *want* a graphics accelarator that just takes
standard quickdraw calls and pipes them through its own internal
hardware quickdraw processor... Is there one out there?)  Every time
you do anything of that sort...

This means that if you're doing a lot of memory work (such as running
a pict through a filter, quicktime movies, etc.) the 2vx is going to
slow down a lot.  The 2vx is faster at things like floating point
calls (is it true that Apple dropped the SANE traps for sys7.1? - can
anyone confirm/deny?) and large amounts of work on small amounts of
data (lots of cpu/fpu calls on memory that is in the cache).

Supposedly the 2ci will be as fast or faster than the 2vx for
just about everything if you add in a video card instead of using
internal memory because the 2ci is slowed down immensely by the
conflicts on bank A.

Somehow I get the feeling that they had to port the UNIX kernel to
Alpha before it would run.  Hardware independent?  Just how would that
work? 

The 100 MHz RISC Alpha implements a superset of the VAX (very CISC)
instruction set?  Are you sure of that information?

I read in the Mac the Knife column of MacWeek that the rumoured LCIII
(sorry travis) might be faster than the 25MHz that's been talked about
so far -- any ideas?

Won't this new LC along with the Centris machines squeeze out the IIvx?
If the LC is any faster than 25, it's going to beat the IIvx for
performance, and the rumoured price is pretty low. Either the new lc
is going to be more expensive than projected, or the IIvx/vi are going
to drop considerably, like 25%...opinions on how the new lineup will
shape up pricewise, where adjustments will have to take place?

it had a 16bit data path.  There are also things to consider like will it have
a cache, will it have an FPU, what will the external bus speed be??  I don't
think the new LC will be of any threat to the sales of the ][vx.  That
wouldn't be too bright from a marketing standpoint.  We'll just have to wait
and see.   TTYL, Joe

Probably depends  on the machine it's hooked up to.

The reason you probably haven't gotten any replies is simple: the MiniDock

Hi fellow netters,

  I have a PB100 which will be one year old in January.  Recently, the
battery has been giving me less and less operating time (as little as 15
minutes after a night's charging !).  I wonder if anyone has experienced this
same problem and whether it indicates that I need a new battery (anyone know
a third party source ?), or the connection between the charger plug and PB
(which seems pretty loose to me) needs to be repaired under Applecare ?
  Any advice appreciated !

Originator: wdp@gagme

Date: Fri, 18 Dec 1992 23:48:16 GMT


Greetings:

I am considering the purchase of a Mac Performa 600 (either with or w/o the
CD-ROM drive).  What I am seeking is serious, non-predjudicial
information on this machine.  

I would like to know...

What, if any, are the limitations of the Performa version of Sys-7 and
how hard (expensive) is it to install the original Sys-7 or even a
later version of Sys-6?  

The machine claims to be a 32 mhz clock speed.  Is this real? Or is
there some reason that the P-600 is slower than other 32 mhx 030
based machines?

The system I am looking at has, I beleve, a 160meg HD. Does anyone
know about the speed of this drive?  Reliability?  

What aout the CD rom drive that is included with the P-600CD?  Is it
up-to-snuff?  Is it as fast as, say, an aftermarket drive? 

Basically, I am interested in the system because it has a lot of the
features that I am looking for, and seems to be fast enough, plus the
$$$ outlay is reasonable (for a MAC that is :->) About 2000 for the
P-600 (4-160 512k vram) and $2500 for the CD version (5-160 1 meg
vram) w/o monitor.  This is at (uggh) Sears and includes a year of
on-site service and tech support (???) as well as Claris Works bundled
software, extended keyboard and several CDroms to start with.

My main purpose is DTP, but I will want to also use it for other
functions like data base and maybe communications.  

What are the shortcomings of this machine, the strengths, peculiarities?  
I would like neutral advice, please.  I know that the Performa series
is aimed at the household market.  But I have a limited budget and
would like to get the maximum speed, storage and usability for my
buck.  I really want to get the Mac, most of my files are Mac, but
now-adays with the DOS (sorry for swearing) machines coming down so
low in price, unless I can get something like this Performa for this
kind of money, I might be forced to look at the DOS.  Please save me
from this fate.. give me some advice :-).

E-mail is prefered, since I have only a limited time to read news.  I
will summarize my findings to the net.

I could also use a piece of advice on decent, yet inexpensive laser
and/or ink-jet printers that may be useful for DTP on this system.

Thanks in advance.

Hi.

I have a NEC 3D and a 5FG monitor, and neither one will work
as an external monitor with my PB160.  Both works fine with my IIci
(with either the internal video or a RasterOps 24STV card).

I've used Compaq VGA monitor here at work as an external monitor
so I believe that the PB isn't broken.

I am assuming that the problem is with the cabling/connector between
the PB and the NEC monitor.  I sort of remember somebody else posted
a message concerning NEC monitors and how they were wired, but
cannot find it.

Does anybody know how I can get the NEC monitors to work?  Any info
would be mucho appreciated :-)

Also I was wondering if it is possible to control the brightness
level thru software? (I imagine it is).  The slider control on my
PB seems to have only 2 positions - either completely off or full
brighness.  It'd be nice to be able to control the level thru a control
panel or something.

thanxs.

The problem is that HD SC setup is a lousy utility. It only works if the disk has Apple Boot Blocks. Of course, any SCSI drive should work in the Mac, but you'll need a special utility to do the low-level format and install the boot blocks. I've used StorWare (1-800-422-2115 or (714) 498-7945) to format several disks meant for SUN workstations in Macs and they all work well (although a Maxtor 207 needs to be set to SCSI ID 6, strange but true).

My advise is to buy ANY SCSI drive and buy StorWare. I've found that drives that are set up for Macs are more expensive (big surprise, a Mac product that's expensive!). Decent drives come from Quantum, Conner, Maxtor, Fujitsu, and a few others. For guidance, look in the back of a Mac Magazine at the drives they sell.

Does anyone else have a problem with the lower left corner

little, as if that corner weren't mounted properly.

Except for that, I find the keyboard decent, but not as nice
