It looks as if the IIsi's onboard video system has muddled up
yet another published performance comparison! Arrgh... 

Because the onboard video system allocates its screen buffer in the memory
bank that contains the first megabyte of RAM, the CPU must share access to
this bank when it is running programs in this bank.  

This causes a *significant* performance drop in raw CPU speed (25-30%) for
programs running in this part of RAM.   

The LCs have dedicated video RAM, so they don't have this problem.

In the MacUser comparison (May 92 p. 79-81), the IIsi's performance was
_very_ comparable to the LC II probably because of this idiosyncracy.  

I suspect that the programs MacUser tested ran into this CPU/Video conflict
resulting in the poor performance rating for the IIsi.  There's no way that
an LC II could beat a IIsi in raw CPU speed.  Just the difference in clock
speeds should make the LC II to be 20% slower than the IIsi.  The inferior
bus should make things even worse.

The CPU/video problem can be fixed on the IIsi by setting the RAM cache (in
the memory control panel) to 512-768k.  Maybe I'll write MacUser and ask them
to repeat the tests with such a cache setting.  I'm sure the IIsi could redeem
itself.

In the meanwhile, I've run Speedometer tests on my IIsi and on a Classic II.
 
The figures for the Classic II should be about the same as those for the
LC II because they both have 16 mhz 68030s with a 16 bit bus.

Here's what I got:

Machine                                    CPU Rating (Mac Classic = 1)
-------------------------------------------------------------------------

Classic II                                  3.98

Mac IIsi (with cache setting at 16k,        3.86
and no other programs running)						

Mac IIsi (with cache setting at 768k)       5.30

Mac IIsi (with cache setting at 16k but
with a 1 megabyte program running below
speedometer in memory)                      5.30


It think that just about says it all.

Subject: So where's my printing bottleneck?
Date: 9 Apr 92 19:23:51 GMT
Organization: Data General Corporation, Westboro, MA

Hi, folks.

I looking for some ideas about how to speed up printing for
the following configuration:

Hardware:
	- one Mac II
	- one Mac IIcx
	- one LaserWriterIINT
	- all three connected via LocalTalk

Software:
	- System 6.0.5
	- networked via TOPS 2.0 (ancient, I know)
	- main application is PageMaker 4.2
	- also FreeHand 3.0

Printing a PageMaker document seems to take forever.
I've been told (and my own experience verifies) that
PM spends an awful lot of time downloading fonts.  Printing
PM documents in general wastes a lot of time at the 
graphic design studio that uses this equipment.

Some things I'm considering:

	- switch to System 7 to eliminate the need for TOPS
	  (or am I confused about this)

	- buy an Ethernet card for each of the Macs

	- Upgrade the printer to a LaserWriter IIg which
	  is faster and has an Ethernet port and scsi port

	- get a scsi disk to store fonts directly on the printer	

	- or buy a different, faster (cheaper?) printer and a third 
	  Ethernet card for it

So which of these steps is going to make the biggest performance
difference?  Will simply changing the printer so that it
has the fonts resident solve 90% of the problem?

I'd really appreciate any comments about any of the above.

Thanks in advance,

	Quite a long time ago, we bought the Mac Display Card 8.24 GC for

using the machine much.  We recently upgraded our version of QuarkXPress to
3.1 and had more trouble than usual last week.  There's a rumour going round
the office that system 7.0 will do away with these problems.  I'm skeptical.

	Can anyone out there offer me any information or advice on the

 The software I have with the Spigot, ScreenPlay 1.02, doesn't have an option
for greyscale, it only captures in colour (still and movies).

 To save a greyscale movie you select a greyscale option from one of the
compressors. I haven't tried this though so I don't know what kind of
performance you get. The standard video compressor doesn't have an option for
greyscale, only 16 bit colour so you may have to experiment with other
compressors.

I know of at least three other cases where the PB170 screen is missing
three pixels. Apple repairers have indicated that if there are more than
five missing pixels then the screen will be replaced under warranty.

Has anyone else noticed such problems with the PB 170 screen, and does the 
number of missing pixels seem to increase over time. You just need to turn 
your screen black to see the number of missing (white) pixels on a 
PB 170 screen.

As one of those 'techs' that thinks he knows more than the average consultant
(I do ;-> <-- Smiley no flames) does there is a very good reason why I didn't
give out things like that to people who I did not know (particully their
technical competence) when I worked in a service department...

1.)  Several manufactures do not want you to give out technical information
because that may be interepted as letting customer's service their own units. 
A big no-no because with particully a monitor you can hurt you or your monitor
very seriously.

2.)  Which relates to (1) there is a liability concern.

Is this average or is it worse here? Do I get a better deal on this here
($919 plus tax after the refund for the old board) or should I check out
normal dealers as well?

How have others experiences with the upgrades been? Any problems with

There is a "new" terminator made by Apple that originally was included with all
IIfx's. This new terminator, which is black, includes some internal cap's to
reduce noise and rebound on the SCSI bus.

It is "required" for any IIfx, although some people have had luck not using
it with _small_ SCSI chains... Best to just get it and use it too...

PS:  I've also heard that the IIfx-term "helps" IIci and IIsi SCSI too...

Greetings!

  I've got a Mac IIx with three external SCSI devices:  LaCie 105Mb
drive, a Mass*Micro DataPAK, and a home-built Toshiba CD-ROM
connected thusly:

  Mac --> LaCie --> Toshiba --> Mass*Micro --> (Terminator)

  I use the Toshiba and the Mass*Micro relatively infrequently, so
I'd like to just leave them off most of the time.  The problem,
however, is that the terminator is on (in, actually) the Mass*Micro,
and doesn't seem to work properly when that device is powered off.

  What I'd like to do is put a switch in, like this:

  Mac --> LaCie --> Switch --> Terminator
                           \-> Toshiba --> Mass*Micro --> (Terminator)

  With this setup, I could have just the LaCie, and a proper
terminator, or all the devices, and a terminator in the Mass*Micro.

  So, two questions:

  1)  Where do I get a 2-way SCSI switch.

  2)  Although I'll believe that this will work fine if I switch
while everything is powered down, would it be possible to set this
thing up so that I could bring the Toshiba and Mass*Micro online
when the machine is already up?  Presumably turn them on, let 'em
spin up, then throw the swtich and use SCSI probe to find and mount
them?

I have a couple of Quantum 80 meggers (model number Q280 I think) in a

won't; it refuses to start up (just the flashing "?"). The
Quantums carry no termination; I tried various options including an
inline terminator on the back of the HD-30 cable plus a terminator
at the end of the chain. The PowerBook is happy with an old Rodime
S20+.

And no, I can't try it with just one of the Quantums because they're
all wired up with power supplies and ribbon cables, and I'd have
to dismantle the rack case and unscrew a lot of things to isolate one.

One thing I might try if I feel brave is to start the PowerBook and then
plug in the drives and see if I can see anything with SCSI Probe, but
I don't like plugging in SCSI while things are powered up...

P.S. Yes, the SCSI ID's are all unique.
