CRC is much better for detecting errors than checksum.

The probability of an undetected error occuring when using a 17 bit
polynomial is around 1 in 10^14.

If transmitting at 9600 bps around the clock, it would take about 3000
years for a single bit of undetected error to occur.

My first computer was an Apple II (not a II Plus)--16 K of RAM, no hard
disk.  I had to pay extra for an RF interface to connect it to a TV set,
and had to provide my own casette drive for the tapes.  It cost $1149
for the computer alone.  Nowadays $1149 can get you a Mac Classic II
with a 40 meg hard disk and 4 megs of RAM (if you shop carefully), or
for $899, you can get a PowerBook 100 4/40 at the Price Club.  Times
certainly have changed, haven't they? :-)

Hello,

I have two old, but nice packages for sale:
Norton Utilities 1.1 
Microsoft Word 4.0
They are both opened, but in mint condition, and have boxes, disks,
registration cards as new ones.
They are both upgradable, but are much nicer in these versions for small
machines - faster, take less space, less enhanced, but safer, and very
useful.

If you have any offers, please e-mail me 24 hrs a day, maybe you can offer
other old packages for trade.  I still use old staff with much more
success, than upgraded versions.

Presumably, that chip (which is not "Alpha", since that names an architecture
:-) won't go in portables or handhelds.  If they feel the need to consume the
portable and/or handheld market, they can scale the power usage down (possibly
by cutting down on the computational power, but how many people mourn that

That's only where part of the performance gain is to come from; according to
the recent IEEE Spectrum article, they plan to increase the clock rate, the
number of instruction issues per instruction cycle, and the number of
processors, all to achieve that x1000 boost over the lifetime of the
architecture.

I'm surprised that the main focus of this thread seems to have become one
of keyboards VERSUS pen-based.  Why do so many people seem to look at this
as an either/or proposition?  Have we all gotten so attached to the idea
of computers as general purpose machines that we can no longer even 
conceive of types of computers that are more narrowly focused in their
usefulness?  

Pen-based computers are better suited to certain tasks and certain types 
of people than keyboard computers, and vice versa.  Even if Newton turns
out to be as perfect at handwriting recognition as anyone could dream,
keyboards will be around for a long time.  Myself, I type much faster
than I write; the best handwriting recognition software in the world isn't
going to make me want to give up my keyboard.  I will likely eventually
find myself using a Newton IN ADDITION to a "normal" Mac, for situations
and purposes for which a keyboard is not appropriate.

If someone else doesn't know how to type and doesn't want to learn, it
will certainly be nice when he is not forced to use a keyboard in order
to use a computer.

Let's hear it for choice and stop talking in terms of "forcing" anyone
to do anything, ok?

Dear all

During the last 3 months or so I've tried  to get upgrades for the softwares
mentioned above, and at both occasion I've been asked to return the original
disks to the distributor to verify that I have actually paid for the 
software. 

I feel that this shows a great mistrust to the customers from the
distributors and wonder what others think of the idea. Is it fair or
are they just trying to make things difficult for the majority of the
honest customers?

I'm writing this because I did return the disks to SoftLine to get the upgrade
for Fontographer and the disks were lost in the post (even though it was
registered and the Post Office is still trying to locate the parcel) and it
cause me major hassle to get the new version.

If you have similar experiences of getting upgrades I'll like to hear from you.
You can either post your reply to this newsgroup, to open the discussion, or
mail me personally and I'll summarise peoples' experiences (good or bad).

In all responses, please include the name of the product and the distributor/

Try formatting a brand new disk on your IBM. Then made a copy of it using
Apple Disk Copy 4.2 onto your Mac hard drive. 

When you want to use an old Mac disk in your IBM, simply make a copy of
that stored IBM disk onto the Mac disk using Apple Disk Copy 4.2.

Hi everybody,

Sorry if this has been discussed recently but I do not usually have time to
keep up with this list...

Here it is: Is anybody familiar with the Andor One card that supposedly gives a
PC the ability to run Mac software?  Someone handed me an article from a French
magazine that says this card offers:
	- 1 68000
	- 1 MB RAM (up to 4MB)
	- 1 AppleTalk port
	- 2 SCSI ports
	- 1 audio out port

The article says that the card is twice as fast as a Mac Classic.  I find it
difficult to believe. There's one gotcha though: you have to provice Mac ROMs
and the Mac OS.

BTW, it seems it only accepts Mac 512 or Plus ROMs.

Any information on the performance of the card, where you can get it, quality
of support, bugs, ... are welcome.  I will summarize.

I bought the "new" TurboMouse.  There are many differences...  They
are functional, though, not cosmetic.  The hardware has been modified
to control more aspects through software (button assignment, etc.) ...
The problem I have with it is that the init needs to run every time

battery and PRAM in it which would save your settings...  For this
reason, I am a little disappointed with it.  Otherwise, I'm happy.

This kind of logic really bothers me.  How do you arrive at the conclusion
that they are "far too slow"?  For 3D graphics and scientific computing
they are very slow.  For word processing and terminal emulation they
are perfectly acceptable.  I'm typing this on a Quadra 900 right now and
guess what - I don't find it any more desirable than the Mac Plus across
the room.  I suspect that a Mac 128 with MacTerminal would be fine too.

I think that Apple did the right thing with the Classic; they refined
the Plus and brought it down to a price level within the reach of students
and other budget-minded users.  When they find they need more power, they
can sell it (providing an even cheaper Mac for the buyer) and get something
better.

Each year the entry level machines get more powerful, but the price stays
about the same (around the $1000 mark).  I think Apple would do better to
keep a base level machine like the Classic but continue to lower the price
instead of upping the performance.  One rumor I have read is that Apple
will introduce a version of the Classic with ROM-based software and printer
to be sold through consumer channels next Christmas for about $1000.  If
so I think they will do very well with such a product.

I think it all comes down to this: if a particular machine is profitable
for the company they will continue to market it.  Now I know this gets
complicated by the fact that System 7 and newer applications want lots of
memory and faster CPU's.  Still, I know LOTS of people that never use their
macs for anything but WORD PROCESSING.  They are completely happy with their
Plusses, SE's and even 512's and 128's!  Why do you want to force them to
buy more computer than they need at a price higher than they can afford?

For me, I would not be satisfied with a lower end Mac (I have a cx), but
the PowerBook 100 looks very attractive at its current discount price
as a second machine.  Many years ago Apple set out to make an "appliance"
computer for "the rest of us".  Selling their low end machines through
discount stores FINALLY shows hope of fulfilling that promise by offering
some real competition to low-end IBM clones.
