To a desktop machine the SCSI DiskMode "hard drive" behaves like a standard
Macintosh hard drive.  The driver that is loaded by the boot code (or
something like SCSIProbe) is the Apple HD SC Setup driver that is installed
on the internal Duo hard drive.  Unless you unmount the drive by dragging
the drive icon to the Trash in the Finder you should *NOT* undock the Duo
from the MiniDock (if you did the results would be the same as if you cut
power to a mounted hard drive...you will start to get disk access error
dialogs.)

Treat the SCSI DiskMode drive as if it was a normal external hard drive.

Was there a problem after he connected?  All phone lines, whether local loop or from
PBX have an applied voltage.  That's what the phone uses for power.

My modem port in my SE/30 just died. Or at least it was dead when I came fro
holidays. It won't talk to my HP48sx nor my modem, and my Printer port
works with both of them.

Which chip is fried ? Is it possible to repair it myself ? I guess it
is not the SCC that is dead because the othrer serial port works OK.
I do not have any of the Mac repair books, but if necesry I can get
one of those.

Any help appreciated.

Well, if that's all it is, I can replace it myself.  No warranty left

A
I am interested in any opinions on this videocard and this deal from Macdepot.
I just bought a IIci and would like to upgrade to 24 bit color if I can find a decent affordable videocard.  Also, I am aware that since the IIci's use the     
internal ram for video processing that any additional RAM installed in bank A   
may actually SLOW the machine down! This concerns me because I am planning on
installing a total of 12megs in my machine.  

Specific questions I have:

1) Is this board really slow?
2) Will this resolution (640x480) look decent on my new 14" Macintosh monitor?
3) they claim this will give me 16.8 million colors.  Is this true?
4) Any comments on MacDepot?

and anything else that might be helpful, perhaps other cheap, but good alternatives.

I will be purchasing a NEC CD rom and would like to display photorealisti
pictures.  

This Macdepot deal was advertised in the Jan '93 issue of MacUser on pg 271.
For anyone interested their order # is 1 800 222 2808.

If it's similiar to the existing POWER chips, the fixed point unit has
32-bit registers, the floating point unit has 64 bit registers, and
it allows a real address space of 2^32 bits (virtual address space of
2^56 bits).  Looks like a 32 bit architecture to me.

(and the current POWERStations seem to be standing a chance....)

I am having problems with my Duo Hard drive and I was wondering first of
all if
there is anyONE else having similar problems and second if anyone can help.
Here is the problem.  First the equipment.
Powerbook 230 4/120 (original RAM and HD).  I reformatted the drive with
the
DiskTools floppy to take advatage of the unused HD space that Apple leaves.
System 7.1 (only system that will run).  Extensions: Quicktime,
Autoremounter,
(both are supplied from Apple), Behierarchic1.05 (hierarchic menues),
Superclock 3.9.1, PopChar2.5.2, SCSIProbe 3.5.  That is it.  I also have a
duo dock and monitor.

 Here is the problem.  Everytime I use the power interrupt button in the
back I
loos the HD.  It gets corrupted and won't boot.  I have to use MacTools2.0
to recover it.  It is a total pain.  It shuts down normally under the
finder, but whenever I am forced to do a hard shutdown (button in back).  I
loose the HD.
  I ended it up reformating my HD and installing a virgin system. This
seemed to
repair the problem.  The HD would survive a hard shutdown.  Then it
happened
agan last night!  Arrgggh.  This is very frustrating!!!  Any help out
there?

I had an SE/30 that got stiction twice! The first time was within the first 2

out, so I bit the bullet and bought a Quantum LPS 105. Later, I found out that
Apply had a silent recal program for some SE/30 drives, so I put my stuck 40
meg back and had it replaced for free! Now I just need a case for the 40 meg
so I can have a nice little portable. Bring your computer into the local dealer
and see if your drive's serial number is in the applicable range for free
replacement. By the way, the replacement drive is a nice Quantum, not a Sony.

The manual for the Radius 24xp lists timing specs for the board as configured
for a variety of monitors.  Here's some excerpts from that list:
 
Monitor                 H x V         H scanrate      V scanrate      pixel clk
-------                 -----         ----------      ----------      ---------
 
Apple 16" mode          832x624       49.73 KHz       75 Hz           57.283 MHz
SVGA mode (72 Hz mode)  800x600       48.00           72              48.000
 
Apple Hi-Res RGB mode   640x480       35.00           67              30.240
VGA mode                640x480       31.50           60              25.175
 
I believe these are the modes available for generic multisync monitors.  I am
using the Apple 16" mode with my SuperMac 17" tube.  The modes can be configured
in at least two ways.  At start up you can force the video card to enter a
test mode, where it slowly switches from one display configuration to the next,
and you can wait for the correct screen appearance, and hit a key to lock in
that configuration.  You can also access the configuration options in the
Monitors control panel, by hitting the "Options" button with the option key
held down.  It is possible to switch configurations on the fly (without
rebooting) if I remember correctly.

You should probably contact Radius Tech support for definitive answers before
you buy:

I don't know about the PowerPC, but the RS6000s are big-endian.
There's a load and store byte-reversed instruction, but that's about
the only concession to other 'endianness'.

Step #1 - Contact the guy you bought it from and find out how he
did it.

Step #2 - (If Step #1 fails), let us know the brand and model # of
the ESDI hard drive and adapter so we can better help you.

I have matched sets of Hitachi ESDI drives w/SCSI adapters that
work beautifully, so long as you don't touch a single jumper -
But in that case, the ESDI drive must be set as Drive 0 and ESDI
terminating resistor must be in place.  On the SCSI adapter card,
the address can be anything that doesn't conflict with the SCSI
bus; and the adapter's terminators must also be in place.  These
are 5 1/4 FH+ drives, so they must be in external cases and they
must also be externally terminated if the last device in the
string.

Also, if you are expecting Apple's HD SC Setup to see the drive -
that won't happen.  Since the drive does not have the Apple ROM, it
will have to be formatted and initialized by third party software,
such as Disk Manager, MacinStor, etc.  After that process, you
revert to the Apple Installer and continue on as per usual.

Hope this helps a bit.

On the other hand, I have OMTI adapters that are not so
persnickety.

Never try to use a battery that the PowerBook has declared empty. I know that
you can get a few extra minutes from an almost dead battery, but there's a
danger that a cell inside the battery will reverse or go dead. When this
happens, the only way to charge the battery is to zap the cell that went
dead or replace  it.

It is also possible that there's a problem with your powerbook, but from
your description, I would bet that you killed the battery.

Keywords: 68000, accelerate, Total Systems
Date: 29 Dec 92 00:26:53 GMT
Organization: Rutgers Univ., New Brunswick, N.J.

About half a year ago I decided to upgrade my Classic and asked the NET for
recommendations. Probably because there were not too many people that had
done a Compact Mac upgrade, I got few replies.

After that time I have upgraded my Classic and have been running it with a
Total System's Gemini Classic (50 MHZ) with FPU for about 3 months now.
I believe a lot of people out there who are not satisfied with the 
performance of their compact Macs will be interested in my experiences. So
here it goes.

First of all, the performance improvement is great! It is now faster than
an IIfx. I cannot stand the speed of even an SE/30 anymore. Speedup is
most noticeable in Math and CPU intensive tasks. The least improved are
disk accesses.

Secondly, there have been very few compatibility problems. Actually, the only
one I experienced was not really incompatibility: the machine is now too
fast for a time-based game (SQIX, if you want to know) to be practical.
Some software that I downloaded from ftp sites bombs, but, you know, you are
never sure whose fault it was. At least, what worked before still works now.
That is good enough for me.

I would also like to say something about Total Systems. I think this is a 
very nice company and pleasant to deal with. I actually had chances taking
to their sales manager and head of tech support when there were such needs.

Overall I am very happy with the upgrade. If you want to hear more, please
let me know. I will NOT reply personally but will post subsequent articles
instead, as I believe this is a subject of general interest. I will be
happy to answer any questions about my experience with the accelerator and
its software, the installation, and with the Total Systems, etc.

Happy New Year and have fun with your Mac.
