>>>Can't be so.  Mitsubishi makes a 35" monitor.

I believe the unit you speak of is FOUR TIMES SMALLER THAN MINE!!
Explanation: when it was first announced (The Mitsubishi) I was willing to
spend the 4,000 dollars for it (REALLY) but was told it ONLY DISPLAYED
640*480 pixels!!!! My monitor is 1280*960 (my 24 inch Moniterm) and thus
has FOUR TIMES AS MUCH SCREEN AREA than the "older" 35 inch tube you claim
is bigger than mine (four times as less pixels)

regarding "Sony makes a 28" monitor (20" on a side) that displays
2048x2048" from the previous post... I have spent no less than 7 hours
straight on the phone once trying to contact Sony about their high end
monitors (I had a very simple request.... Whats your best)

I was told to call CPD (Consumer Products Division) They said I had to call
the professional broadcasting division. That department said I had to call
the specialties group, and then I was sent back to consumer electronics. I
never ever ever learned what Sony's largest MULTISYNCING monitor was.

This 2048 by 2048 makes me disbelieve you if the current smalles trinitron
pel element for a tri-phoshor group is 0.25 millimeters horizontally and
(guessing) 0.4 millimeters vertically then for a vertical resolution of
your claimed 2048 pel elements would measure (2048*0.4 mm = > 32 inches!!!!)
Therefore either it is not a BRIGHT monitor using trinitron shadowmask,
else it is A MARKETING LIE AND A TOTAL MYTH.

I rest my case. Until I see otherwise, I still believe that I have the
worlds largest computer monitor.

Thanks, all, for replying. I just printed them out and message will go to
Philips head office.

2 reactions were positive about the monitor and said it was all Sony
marketing. The others had real complaints that will serve as illustration for
Philips head office (and I have left out names of people who asked me).

One thing though. These Monitors are not sold as Philips, but as NeXT. Which
means that NeXT is responsible. I could for instance not blame Philips except
for shortsightedness if NeXT and Philips would have a contract where NeXT
accepts monitors without the usual test because of price considerations. So, I
want to know what NeXT has done about these monitors.

This is my first post, so please bear with my foolish mistakes.

I am planning on buying a NeXT sometime next year and have several questions
about external hard drives for it:

	1) I know you can use Mac drives on the NeXT, but what is the 
	   difference? I saw a 330MB, 17ms NeXT drive for $1749 while a 
	   425MB, 8ms mac drive cost only $959. What besides the neat black
	   case makes up for the $800 difference?

	2) I've been led to believe that the difference in 1) is that the 
	   NeXT drive uses SCSI-2. What are the advantages of SCSI-2 over
	   the SCSI-1 used in the mac drive?

	3) I'm a student. I have no money. Would I be sacrificing a great deal
	   by saving the $800 and getting a cheaper, albeit non-SCSI-2, mac
	   drive?

	4) If I do opt for the mac drive, what sort of questions should I ask 
	   the vendor to insure that I don't get stuck with a $1000 doorstop?
	   I've heard something about revision 17B something or other, but
	   what exactly is needed for the drive to work with a NeXT?

	5) Totally unrelated question: I presently have a NEC CDR-74 CD-ROM
	   drive that I'm using with my mac. I'm rather fond of this drive
	   and am wondering if it is compatible with the NeXT.

I appreciate any answers from anyone. Please email me at:
	jont@minerva.cis.yale.edu - no NeXTmail, please -- at least not yet!
Thanks alot.

I would like to take the plunge and upgrade my 2400 baud modem to a 9600 V.32,  
V.42bis Fax modem. It looks like the Supra and the Zyxel faxmodems offer the  
best price/performance. 

I understand the NeXT fax support did not work properly under NS 2.1, and that   
B&W has just announced a program that makes the Zyxel work properly with NS 2.1  
and 3.0 (with other modem support promised)

Questions for those with net.wisdom:

1. Does NS 3.0 "fix" the fax support (as NeXT seems to claim), and if so, what  
faxmodems work without 3rd party software additions?

2. Can someone tell us how well B&W solution works with Zyxel modems? I heard  
that the earlier ROM version of the Zyxel has fax-bugs (version 4.13, I think).  
Is a later ROM version required with this modem (version 5.xx)?

3. Does anyone know how the Supra modems compare with the Zyxel?

Thanks.

I'll summarize private mail responses.

RE: "Seventh grade geometry wasnt your specialty eh? "

I know that talking about pixel size and monitor size in the same
discussion can be mildly confusing to follow but my point was that my
monitor was "the biggest". The concept I am promoting is not only that it
is 24" but that it has over for times as many pixels at a perfect square
aspect ratio than a 640*480 grid on the more common 35 inch Mitsubishis.

RE "10 foot diagonal screen"
That is not a glass tube....a "monitor"

RE: "The first was the 2048x2048 monitor"

I would like to know its shadow mask size. evidentally it is much finer
than the tension mask allows on the CPD1302 (a 0.25 mm * 0.4(est.)mm) rect.
It is conceivable that you are right, and that at least one pel exists for
each pixel the system wishes to display, but I am skeptical. The only
factor that lends credibility is the fact that it was Sony and that it was
$40,000.00.

Driving a 2048*2048 display at 60 Hz, non-interlaced, with 8 bits of "data"
for driving each of the three guns sure does add up to a hell of a lot of
bandwidth.

Sadly, many of the large monitors, especially those for nearly static
displays, have a very long persistence and a slow refresh rate and are
unsuitable for even using a mouse indicator. I hope this 2048*2048 20inch
by 20inch tube does not suffer from that.

Hmmm Well if you take the number of pixels per inch as quoted in the
reference manuals (92) multiplied by the height and width using
Pythagora's Theorem (x^2+Y^2= Diaganal^2) you see that NeXT DID NOT LIE
and YOUR MONITOR MUST BE ~15.5 INCHES ELSE IT WOULD NOT MATCH THE SPECS.
 
I guess you just do not like the evil marketing slimy people that round-up
to the nearest inch and THEN ADD THE PHANTOM INCHE OF GLASS UNDER THE BEZEL.
 
Thus a 14 inch monitor is always a 13 inch tube, and most 15 inch monitors
are really 13 inch tubes. Lukily a 16 inch is a sixteen inch and thats
what you have. PS I am writing this ON THE WORLDS LARGEST COMPUTER TUBE
MONITOR... A Viking 24 inch from Monitorm (R.I.P.). I know its not exacly 24
inches diagonally but as long as I always own the biggest and best I don't
really count the inches.

I'm now the proud owner of a NeXTstation TURBO and am thinking of
using its DSP and/or Audio port of some scientific/acousting

  1) Is the audio input (condensor mic on front of the mono monitor
     and corresponding audio IN jack in the back) handled by the DSP
     or by another dedicated A/D converter?  What is the frequency
     response of the audio input?  How wide (bits) is the A/D
     converter that drives it (if applicable)?
  2) Generally, what kind of cables/interfaces (or how do I go about
     finding out) are available for the DSP port on the NeXT?

I am specifically interested in ways to interface the audio
port and/or the DSP into some test equipment that generates analog
signals.  Anyone have experience doing this?

>>Or am I dismally forgetful here?

Yes, in this case you have it backwards, AND you are accidentally
attributing the Mac 128K Mac 512, and Mac+'s problem with only supporting 
very very fast interrupts while floppy was transmitting, with apples 22
other computers.

Only the oldests Macs favoored one serial port over the other. 

All Mac II class devices, and SE etc. can handle 57,600 baud just
fine. And that 57,600 baud rate is using 16 times oversampling
on the serial port. In synchronous blocks, the Mac IIfx for example
can handle about 900,000 baud according to Apple. And of course
EVERY Macintosh EVER made since January 1984 is capable of 230,400
baud, for supporting LocalTalk transmission (normally done of
printer port by convention but can be reprogrammed.)

At 230,400 baud Apple is doing 4 times over sampling with the Zilog chip
for reasonable protection against Clock Drift for a 600 byte packet.

I and a friend rewrote Apples serial port to do DOUBLE the 57,600 baud
rate in order to support our Telebit Worldblazers. In fact using
BOTH ports AT THE SAME TIME was possible at 115,000 baud on a non-cached
non-accellerated IIci at my friends place, using a cable direct from one port
to the other. 

ZMODEM transfers were done at 115,000 baud IN AND OUT on two ports and
no problems were encounterred other than near total deprivation of
CPU time to the Mac. (So severe that VIA was not advancing system clock
time, though I hear that Apple has other goodies that recalibrate the
TickCount to the Real Time Clock in spurts (See Develop issue #10)

Believe me, The Mac handles serial better than the NeXT allows currently.

And the computer I own (A IIfx) has dedicated computer subsystems using 
65C02 processors to handle the serial ports. (This is a feature that was
discontinued by Apple years ago and was only put in the Mac IIfx)

You don't need to respond that the Mac hardware sucks when compared to the
NeXT because I totally agree. But The Mac has always had the greatest
communications capabilities in the world and based on the AMAZING hardware
and software goodies demonstrated at WWDC 1992 It will always have it.

Hi,

I just saw a previous article confirming that the Sun CD-ROM works on a NeXT.
Has anyone tried a NeXT CD-ROM on a Sun?  I first changed the SCSI number from
the factory setting of 4 to 6.  That got the Sun to recognize the CD-ROM drive
at reboot time.  Then I tried to mount the CD-ROM with the following command:

mount -r /dev/sr0 /cdrom

This caused repeated overflow messages, and the drive never mounted.  Is there
a mount option such as rsize that I need to use because of different buffer
sizes? Thanks for the help.
