A cache or cache card is a hardware extension to the processor that allows
the cpu and memory to run at different speeds. There are several types
of caches. Take an instruction cache for example. Suppose the cpu wants
to execute the instruction at memory address 123. The cache hardware
first looks in its internal (very fast) memory for that memory value.
If it's present, it delivers the value to the processor. If not, it reads
main memory locations 123, 124, 125, and 126 [for example], delivers
the value at 123 to the processor and remembers (i.e., caches) the others.
Since it is very likely that the next instruction the processor will execute
is at location 124, and the value of 124 will still be in the cache, the
processor + cache combination eliminates a comparitively slow access
to main memory.

Caches can operate similarly for data, and for memory writes. Writing
data is a bit tricky, however, since the processor may write word 123
then immediately read word 123. Here, the cache must deliver the latest
value of that word, and not an out-of-date value that might be left
in the cache.

Caches gain some performance by knowing that instruction accesses are
supposed to be read-only, so it can bypass write-checks for instructions.
This is a problem for programs that dynamically modify the instruction
stream. If a program must do this, the program must explicitly inform
the cache by executing a "cache flush" instruction. (There are similar
problems for concurrent I/O operations.)

Caches may be built into the cpu hardware or available as add-on boards.
There is a noticable performance improvement for cpu-bound tasks (I recently
added a cache board to my Mac-IIci), but your experience will depend
on the kind of programs you run.

Of course, the above explanation has simplified matters considerably; you
should read a computer architecture textbook for more information.

I recently bought a used external hard disk for my Mac Plus and it 
seems to have died on me.  A few days ago when I turned on my machine 
it just gave me the question mark.  So here are the things I've done 
so far...

I put it on my Mac IIci at work so I could try to diagnose the problem 
(by the way it worked on this machine before too.)  My drive was 
formatted with Silverling 5.31 and when I first tried running 
Silverlining it took forever to scan the SCSI bus but eventually came 
up with some device at ID 4 (the address of my external drive).  It 
first said that it could not access the drive reliably.  So I left the 
drive running for several hours, thinking that maybe the humidity in 
my basement apartment had something to do with it.  Several hours 
later I tried the same thing and it found the device quickly with no 
problems.  I can't remember exactly where it balked this time, but I 
decided to leave it for a while again.

When I tried again to mount it with Silverlining I got the following 
behavior which is pretty much the current state of things.  I start 
Silverlining and it finds a "ZFP 40" at ID 4 as it should.  I select 
it and it comes up with the dialog showing the name and size of the 
partitions, etc.  I select mount and then hit Update and I get a 
message from the finder that the volume cannot be used because of an 
error of type -127 (whatever that is).

So I decide to run the tests in Silverlining.  Here I get inconsistent 
behavior.  The consistent thing is that *somewhere* in the test it 
gets stuck.  Yeah, it stops and just sits there forever ... I have to 
reboot.  Sometimes it makes it through all of the short tests with no 
problems, sometimes it gets stuck in the seek tests, and it always 
gets stuck in the long tests but not always the same place.

I have a feeling this is a pretty serious problem, but can anybody 
tell me what it is, and is it fixable?  Please tell me that I won't 
have to buy a new drive.  I'm a poor grad student who finally broke 
down and bought a *used* 40MB drive to make his Mac Plus useable ... I 
really can't afford buy another one.

By the way, it's a SONY drive in a CMS external case.

You can get the Tokamac for about $1800 now (from MacWareHouse,I think). I only
have one piece of software left that I have to run in "030" or cache off mode
and that's Typestyler 2.0! If you have the current versions of
Pagemaker-4.2,Quark-3.1,Freehand-3.1,Illustrator-3.2,Word-5.0,etc.etc.,you
should not have to run in a cache off mode. In the 040 mode, the Tokamac is
ungodly fast! I know nothing about the PowerCache but I have never heard of
anything other than the Radius Rocket that comes close to the Tokamac for
speed.

Its an exception (0F) with sub-code code 28;

   Is it a hardware or software problem? Is there a documentation recording
   the meanings of all codes?

It's probably a software problem. The system-file may be damaged so that the
resource that contains the welcome string can't be read. It may also be a
hardware problem with your hard disk. Can you boot from a floppy and then see
the hard disk, then it's a software problem. Else hardware.

I have put together all the information about "Sad Mac" error codes that I have

Does anybody have suggestions on the equipment necessary to add a 14"
color monitor to an SE/30?

If not an super-VGA, how about a VGA?

        I would like to use a super-VGA 14" PC monitor.  It would be really
        great if there were a card that slipped into an SE/30 and ran the
        monitor.

        Is there such a card or piece of hardware?

        Is software required?

        Is it possible to set it up so I can use both the new monitor and

I would get a Brainstorm accellerator for the Mac Plus. Mine cost me
$200 installed. It is basically a 16Mhz 68000 that piggybacks on top
of the existing CPU and one chip is replaced on the logic board. The
logic board chip replacement lets the logic board run at 16Mhz like the 
new processor.

The upgraded Plus is just over twice as fast as a Mac Classic. You can
use hard disks at a 1-1 interleave. Video is supposedly faster.

Best of all, no inits or control panels are required as the software that
runs the Brainstorm is downloaded into non-volatile memory on the 
Brainstorm board by the Brainstorm installer.

System 7 runs great on it. No incompatibilities as far as I can tell.

A very satisfied customer,

Hey folks. . .
   I've been away a while, but I'm starting to get back into my Mac hacking
and had two questions.

1) I have a IIci running System 7 with a Datadesk extended keyboard.  Once in
a while, this *really* annoying thing happens where a key acts as if it were
stuck, and there is nothing you can do but wait for it to stop.  Sometimes you
only get 4 or 5 of a character, sometimes you get a page and a half.  I very
vaguely remember reading this group long ago, seeing some note about 
compatibility problems between the IIci and Datadesk keyboards, and thinking,
"Whew, glad that doesn't happen to me."  Well, it does.  Does anyone know
this problem?  Any suggestions/solutions?

2) I also have a MacRecorder.  I built one of these in college, but it never
quite worked, so I bought one.  Anyway, we built ours to just crank data in
as fast as it could and let the software sort it out if my memory serves me.
The reason I bring this up is that I'm curious about 44 KHz sampling on my IIci
with MacRecorder.  If MacRecorder also just blows the data into the Mac as fast
as it can, I suspect this is possible.  I don't have any software to record
at 44 KHz, but if I know it will work I could write some.

						Thanks for your help!

Hi,
I recently ordered a PowerBook 100 4/40 at Computers Etc.
in Peabody Ma. They say that they ship overseas. There voice
number is (508) 535 52 52 and fax (508) 535 81 71. It is priced at
1100$ plus 60$ packaging etc. But considering the cheap $ it is a very
good price even though  the 60$ are really impudent.

I think it's on the developer CD, called "Sound sampler" or something like

Typewriters are also adequate. So are pens and notepads. Horses are

is walking. Being adequate may be some people's goal in life, but not
mine. I like
my cars with cruise control, my tape players with auto-reverse, my

Is this the bigger case or the smaller model they have.  I think they call

I recently purchased a PB 100 2/20 from WEA. I am trying to connect
it to my IIci at home via the SCSI mode/cable. HAS ANYONE acheived this? 
I purchased a HDI 30 to 50 Centronix cable to connect my PB 100 to my
external hard drives. But IT IS NOT WORKING!!! What is going on?
Is the cable bad?--it is not by APPLE. Or is my PB bad. In the manual
is says that as long as the HDI 30 side is connected to my
PB 100, when I boot, it should show a SCSI icon with the
SCSI id #, but mine doesn't do that. It boots up as usual.
Now, if I connect the other side of the cable (50 centronix)
to the external drive's SCSI port, my PB 100 freezes and
gives me that dumb floppy with ? mark icon. HELP!!
 
Please share your experiences with me, be they good or
bad, I just need some feedback of any sort. 
 
Help!
Lance
