Because of ... $$$

To Gene: Try it out! If I had a IIcx I would have tried it myself.
Actually I have a IIci which I had running at 30 MHz simply by
replacing an oscillator. The bottom line was, everything was fine
and faster, but I was unable to access some of the serial devices
(MacRecorder was ok, but Personal LW LS and Supra modem did no
longer work), and the video cards had some minor problems.
I even tested a 66MHz oscillator for a 33MHz clock, but then the 
machine won't boot.
Of course, everybody does such things on his own risk. At least, 
my machine took no damage so far.

Subject: Question: Repair or replace drive with stiction?
Organization: Mystech Associates
Date: Mon, 28 Dec 1992 14:27:20 GMT

I have an SE30 with a Quantum 40 meg drive.  It is about 2.5
years old.  Recently, the drive has been exhibiting stiction
problems.  A couple of times I had to cycle power before the
drive would spin up and just a week ago I had to remove the
drive and shake it about its rotational axis to get it to
spin up.

So, my question is, has anyone had a drive with stiction
repaired and was it worth it, or is it more cost effective
to simply buy a new drive?

Thanks for your help.

I have an old Sun 60Mb tape drive which uses a SCSI-QIC?? interface card 
and an Archive
tape drive. I tried using Retrospect 1.3 but it fails to find a tape drive 
on the bus
that it understands. Does it do some sort of SCSI inquiry to determine the 
drive type
and then uses an appropriate driver ? How can I convince Retrospect that 
there is a
taep drive at a specified address ? BTW I've used SCSIProbe 3.4 to 
determine that there
is some sort of SCSI device at the nominated address (even though it can't 
determine 
what it is ). Is there some other utility that I can use to backup my hard 
drive to 
this device ?

My local Apple Educ Center heard from Apple that the sticky key/mouse problem
is caused by a bug in the ADB (Apple Desktop Bus) timing routines.
Doesn't this mean that the bug is in the ROMs ???

Subject: Mac IIci memory config?
Date: 28 Dec 92 05:02:49 GMT
Organization: Stratus Computer, Inc.
NNTP-Posting-Host: greer.az.stratus.com

I just upgraded my IIci to 20MB of RAM.  I've seen a number of discussions
regarding performance relating to the video ram on the IIci.  I know the
IIci uses the memory in Bank A for video ram, and I know system performance
can be increased by forcing applications to run in Bank B.  I currently
have 4MB in Bank A and 16MB in Bank B.  I have the disk cache set to 1024.

What experiences/recommendations are there to maximize memory performance
on a IIci with 20MB?

I'm also running A/UX (although I do run the native Mac OS as well).  What
considerations need to be made in regard to A/UX performance?  I've
increased NBUF to 2000 and I've noticed a dramatic increase in performance
(both A/UX and Finder applications).  The Finder Memory CDEV is set to
allow 12 MB to be used for Mac Applications.

Please respond to mp@az.stratus.com.  I'll post a summary of all responses.

Thanks,

Mike

Yes it's allowed. In fact I'm typing this message on a IIci that has
20 MB in exactly that configuration. If the ad says you can't use 1 MB
SIMMs in one bank and 4 MB SIMMs in the other on the IIci, it is

I would imagine it's 64 bits just because of what IBM has learned from
RS6000s. We have RS6000s with half a gig of RAM in them, and have hassles
because the combination of AIX and the 32bit arch allow maximum size data
structures of 256MB. We are not alone in having complained to IBM about
this. It would only make sense to make the new chips 64bits, and to roll
the improvements into forthcoming RS/6000s.
Likewise I have seem people complaining to Apple about not being able to
create files (massive databases) longer than one gig (or maybe four gig---I
don't know quite how many bits of the 32 you have free as offsets into
files.)

We have a lab here with two Q900's and three Q950's each machine has a
microtech 45mb removable cart. drive attached.  Every morning, after leaving
the machine running all night, there is a message on the screen "This disk is
unreadable" clicking on the "eject" key makes this message go away.  If I
unhook one of the drives this message no longer appears.

I have the most recent extension in the sys. folder and each one of these
drives was put on different machines IIci's IIcx's and the message never
appears.  I talked to Microtech and they haven't heard of this happening.
It only happens on the Quadra and only if the extension is enabled.

Has anyone else had similar problems or any suggestions?

Organization: IEEE Service Center, Piscataway, NJ

I finally have it with our LaserWriter Plus. Due to its inability to expand
the RAM, I am always restricted by the maximium size I can print. It's even
worse when I try to print a legal size paper with PageMaker. LaserWriter Plus
basically restrict you to print a legal size paper with very wide margins.

I have seen ads by GCC regarding their line of laser printers. One of the
claims is always the ability to print edge to edge using their proprietary
printer driver. I assume the ability to add more RAM helps also. GCC printers
are Okidata printers with GCC's ROM and may be more.

I would appreciate any feedback about GCC line of printers, especially this
edge to edge feature. Also, are they quick in updating their printer driver
when Apple releases a new System?

Can this edge to edge printing be achieved using a Apple NTX or the IIf/IIg as
long as extra memory is installed, or it is uniquely GCC's?

Thank you in advance.

Is anyone out there using system 7.1 with the Xceed 30 8-bit card in the PDS ?

After installing the card in my SE/30, I can boot from System 6.05 on a 
floppy, but not from the 7.1 Installer 1 floppy or from 7.1 freshly installed
on the hard disk.

Just to make matters worse, It booted fine from 7.1 on the HD the 
first time after installation, until I installed the "Virtual Video" 
cdev and changed the setting to 1K by 1k. I don't have any external monitor 
attached or the internal grey-scale adapter. After removing the cdev, the 
HD system still does not boot.

More generally, can the presence of a card in the PDS influence the start-up
process at boot-time in the absence of any INIT/cdevs for the card ?

Then it's no more 'hardware independent' than anything else.  You
still have to rewrite the kernel code for the hardware that it sits
on.  Check out sometime just what the difference is between the time
(say) USL ships the port kits and people start shipping product.
You'll find that it's long enough to imply there's more than 'minor
rewriting' involved.

If it's so easy, where's Solaris for Intel platforms?  How much work
is NeXt doing to move their OS, which ought to move more easily than
UNIX, since it is Mach-based and has a microkernel design (less to
port)?

Granted that Intel hardware is fast and cheap. I often buy Intel hardware for

The problem is that what people run on it for software.

Unfortunately one cannot separate the value of a computer from the quality of
it's software. You don't just run hardware, you run both.

While OS/2 is a nice operating system, it's market penetration is zilch.
Windows NT is probably nice, too, but it is vaporware, not available for real-
world applicatibility testing (how stable is it? how fast will it be? how much
hardware does it need in real-world use? how compatable is it REALLY?).

People running a GUI on a PC run Windows 3.1, which makes the comparisons
performed by Ingram quite appropriate.

Funny, a Mac will run a 13 year old 8 bit character mode os to an extremely

I sure hope that by the year 2001 I have upgraded to much nicer hardware and
software. The only thing that is important long-term is that you can move your
data to the new box.

The problem is that I need to buy computers for use today, not some indefinite
time in the future (next century?) when MAYBE the OS's and application
software available will have the same functionality as what is available on
the Macintosh, now.

That chip is probably not on the CPU daughterboard, so they only
replaced what was broken. The motherboard doesn't affect at what speed
the daughterboard is running at, so replacing the motherboard with
a part from a PB145 has no effect on system performance.

Thanks for all the info about the 16-bit data path etc.  Nobody answered my

Is the FPU slot in the Classic II designed ONLY for a FPU, or is it really
a strange sort of PDS slot?  Why haven't people made other boards to go into
this slot?

I'm asking because at the time I bought this computer, it was _all_ I
could afford.  I HAD to have a Mac before I returned to college.  I'd
really like something faster / a larger screen.  Unfortunately as a
somewhat poor college student I can't afford these things..  I understand
that the Classic II has Color QD built-in so it can drive a color monitor;
but I would need a SCSI monitor driver right?

Any ideas on making the internal screen a grayscale by switching parts
on the analog/PS board???

Probably not. Apple could only squeeze out 8 shades of gray from the
active matrix display (the other 7 are faked and one of the 16 doesn't
exist at all), so I doubt that they could get 256.

On the other hand, 16 shades of gray is already quite nice, although
you can't play certain popular games with just 16. Those popular games
usually also require a palette/CLUT based video card and Apple chose to
make the PowerBooks fixed palette devices (this means that you can't
use palette animation on the PowerBooks).
