Everytime I read about the new PowerPC Macs and emulation
of the 680x0 chip instructions in software, I wonder if it
isn't a lot more convinient to just make either
1. A PowerPC Mac with a 68040 as a coprocessor. All the
   toolbox will be in PowerPC instruction set, but will be
   trapped if running a 680x0 binary.
2. Just build a plug-in card with a 680x0 as an option.

I recall the days of the Apple II clones running CPM on the
Z-80. Great stuff. Some of the clone makers even went further
to make a motherboard with two chips in it. And a lot cheaper
and faster than software-only emulation.

We were upset here, too. The financial people use the 21" grayscale
displays for large spreadsheets, and the publishing people use them for
large two-page work. It looks like we're going to have to go with a
third party display -- I had been hoping not to do this. I've been very
pleased with the performance of the 21" greyscale from Apple... It's
either that or going with Apple's 21" color, and the price difference is
$2400 Suggested Retail (not counting what can be gotten from cheap
dealers, etc). Too much, since they don't need the color capability.

It is possible to 'dock' a PB 100 so that its hard disk is visible on
the SCSI chain of another computer system.

Is it possible to do anything like this for PB 140 or 170 models?

I need a fast answer in order to help a good customer with a problem. Please
e-mail to the address below as our news reader seems to run a day or two
behind.

This customer just purchased a new CI with an internal hard disk. He wants to
transfer 15MB of files from his existing SE (using System 6.0.X) to the CI hard
disk (using System 7.0). I'd like to simply connect an external hard disk to
the SE's SCSI port, copy the files, and then reconnect the external hard disk
to the CI and recopy to the new hard disk. I'm aware that I'll have to avoid a
SCSI ID conflict, and can change the ID as needed. What concerns me is the
possibility of SCSI terminating problems. The hard disk I want to use has
termination resistors installed. Will I need to change anything to compensate
for the internal SCSI termination on the hard drives of either the SE or the
CI? Alos, if you know of any other 'ha-ha's I should watch out for, I'd be
grateful for any advice. Thanks in advance.

 My wife AND my employer ignore my opinions - feel free to do the same!

Not true. Apple memory expansions work on both machines, but it requires
extra effort to design a board that works on both machines. The PB100
cards have to support 16-bit memory accesses while teh PB140/170 cards
have to support 32 bits.

No. The 68000 is limited to 16MB of memory. This is the total memory
space and you have to leave some room for ROM and I/O. The original
Macintosh had 4MB reserved for RAM, 4MB for ROM and 8MB for I/O. This
made the machine cheaper to make. The PowerBooks reserve 8MB for RAM
and leave the rest for ROM and I/O space. So, the answer is that the
PB100 is limited to 8MB of RAM. The PB140/170 were designed for 8MB,
but with the PMMU in the 68030, you can use tricks to get up to 1 GB
of memory (just like with virtual memory, only it can be physical too).

And indeed these factoids are not true.  Never believe an ad from a superstore.
They tends to give out more false information than true info.  The picture
tube in the 1304 is identical to the one in the Apple 13" except the
1304 has an antiglare coating.  In fact, I believe Sony manufactures the
Apple 13" for Apple.  The Sony 14" trinitron tube has a .25mm dot pitch.
However, it is an apeture grill tube as opposed to a shadow mask tube which
most monitors use.  They're different technologies so it's not really valid
to rate them by dot pitch.  There are are plenty of monitors out there
with a .28mm dot pitch that will kick the sh-t out of some monitors made
with the .25mm dot pitch trinitron tube.

Just to put in my two cents, I like the Sony 1304 also.  Albeit it is
not as sharp as the Apple (this is apparently due to the antiglare
coating), it's less expensive, it's a multifrequency scanning monitor
with a maximum resolution of 1024x768 non-interlaced, and it comes with
a tilt swivel stand (over $60 from apple).

I like the new NEC's better though.  The circuitry in the 1304 is getting
a little outdated, and the new flat screen NEC's are 15 and 17 inch diagonals.

I'm curious to hear about the new Sony 1604 16" monitor for around $1200.
Sounds like a deal.  Does it have the two annoying lines across the screen
like the other 16" trinitrons or did they fix that somehow?  (Don't get
my hopes up right?)

I have been trying to fit a CONNER CP30100 scsi harddisk into a Mac SE to

I am not able to initialise it using either the harddisk setup on the Apple
Harddisk Test Disk, but I can test it OK (except for an invalid partition

I have also tried using some setup software supplier by the Conner agent but
that also fails.
The drive works fine in IBM type devices (I do a low lovel format before I
put it into the MAC). The SE also works fine with a CONNER CP3040 scsi drive.
 
Any ideas would greatly be appreciated, either by posting or e-mail. Thanks.

Now, I am writing:

I got four responses, all very useful. What I undestood is:

1. NEC Silent Writer is very quiet.
2. QMS PS 410 is quiet.
3. Apple Personal Laser Writer is noisy.
4. TI Microlaser is very noisy.

Some more info:

NEC SilentWriter Model 95

50dBA operating, 37 dBA idle, PostScript Level 2, LaserJet III PCL5/HP-GL2,
2MB memory standard, 6 ppm, 250 sheet paper tray, manual tray, AppleTalk,
serial, parallel interfaces, etc., etc.,  < $1500
Recommended from one satisfied home user.

QMS PS-410

Quiet (no data, but this was for me the quiet laser of choice before I heard
about NEC). Adobe Postscript, Laser Jet PCL4, 4 ppm Canon engine (the same
as in Apple's), paper tray, manual tray, AppleTalk, serial, parallel
interfaces, print buffer, automatic printer port and emulation switching,
many control lights, some problems with TeachText documents under Sys 7,
< $1600

Apple Personal Laser Writer NTR

Noisy, although quieter than LaserWriter II or a Mac II. AMD RISC processor,
Adobe Postscript 2, Laser Jet PCL4, 4 ppm Canon engine, one paper input tray,
AppleTalk, serial, parallel, automatic printer port but not emulation 
switching, about $1900 but it comes from Apple

TI Microlaser

Very, very noisy. Has no standby mode, fan pushes at full regime all the time.
Fast engine (9 to 16 ppm), Adobe Postscript, several ports, sometimes comes
with ATM and other software bundled, < $1300 with 17 typefaces, < 1800 with
35 typefaces. A home user likes the speed, but has to support the noise.

I have not yet decided which one I will buy, but hope this can be useful
to somebody. Thanks to everybody who replied.

Well, there might be a couple reasons ...
1) 768k is a very big disk cache.  Maybe too big.  It takes time for the
   CPU to figure out if a block is in the cache, and it may well be that
   with such a large cache your spending too much time looking for blocks.
   If memory serves, the cache only works with open files.  Unless you 
   regularly work with multi-megabyte files doing random access, a cache
   that large isn't going to help anyway.
2) The IIsi probably has a larger screen (wouldn't be hard, eh?)  It
   may be that the IIsi _looks_ slower because windows are larger - which
   take longer to redraw.
3) The SE/30's video isn't accelerated, but it _is_ well done and doesn't
   impact performance at all.  Most IIsi's don't have accelerated video
   either.
4) And, of course, the SE/30 has an FPU which the IIsi doesn't come 
   with.  Doing spreadsheets this makes a difference.

My guess would be 50% of the percieved slowness is from number 2, 
22% #1, 22% #3, and 6% #4.

This is to keep the on-board video from having memory conflicts with
applications.

Both machines are using 13" color monitors.  The SE/30 uses an
unaccelerated card, the IIsi uses built in video (hence the large disk
cache)

My IIsi now has an FPU as well, but this shouldn't have an impact

Subject: LaserWriter NT through serial port?
Date: 9 Apr 92 15:23:41 GMT
Organization: UB

How is it possible to connect a LaserWriter NT to a power book without using
appletalk?  We have an NT hooked up to many different machines via a serial
switch box and would like to add, ironicaly, the first mac.  However, isn't
the laser writer driver only for appletalk connection?
