Subject: Re: Copying Resources
If you want to copy the entire resource fork of a file, the best way by far is
to use the low level file routine
PBOpenRF
to open the resource fork, and then to PBRead's and PBWrite's to do a block
copy of the fork. Use PBClose when you're done.
Note: This is exactly the sort of application for which PBOpenRF was included.
You should not abuse the routine to try to store "data" in a resource fork
(see Technical Note #74.

This is in response the the person who recommends that you don't get the
800K disk and Rom upgrade.
How anyone could say that you don't get more space on an 800K disk that on a
400K disk is beyond me. I don't know a computer in the world that will tell
you 400K is greater that 800K. Who ever recommended that you don't get the
upgrade doesn't understand how to use his system.
1st if you do the simple math there is no way that a 400K disk will have more
free space that an 800K disk, even with the new system.
Old system = about 160K
Old finder = about 47K
Macwrite = about 69K
----------
Total = about 276K
Space Avail= 400K
----------
Free Space 123K
New System = about 220K
New Finder = about 57K
Macwrite = about 69K
----------
Total = about 336K
Space Avail= 800K
----------
Free Space 464K
On the new system with DS drives you have one entire 400K disk at you finger
tips to do what ever you want with it. If you don't have at least 200K free
on an 800K disk with only one application. Then something is wrong. I left out
the ImageWriter driver, but that only takes about 25K anyways, so It's not much
of a factor.
Also the New roms do have casheing, and when you turn it on or off it doesn't
take immediate effect. The cashe is only used when the user quits an
application, or launchs an application. You do NOT have to turn the machine
off. I agree with what the moderator said about the cashe, the fact that
MacWrite doesn't save in the correct manner is not the new rom's problem.
It's the problem of the people who wrote MacWrite they didn't follow the proper
guidelines and now they are paying for it.
The disk swapping problem has been experienced by almost all of us in the
macintosh world. Here again it the fault of the software not the hardware.
Since MacWrite uses the disk to store temporary files, whenever you load a file
(even just to look at it and not make any changes),
off of another disk MacWrite has to make a temporary copy of the file on the
system disk. The swapping that was experience was not to keep looking at the
system file, but to put the temp. copy of the data file on the system disk.
New ROM'S again, No!!! I can duplicate this "problem" on any macintosh that you
give me with only one drive. All I have to do is load a file that is on a
different disk that the system disk. In fact it's doesn't matter where MacWrite
was, memory or otherwise, it's the fault of the MacWrite software and the way
that it stores the data for the file.
As for HFS being considered less that useful. I would have to say that is
opinion rather that an observation.
The print driver is another point of interest. There are some problems with
the ImageWriter 2.1 print driver. But the ImageWriter 2.1 driver is no longer
the proper version. 2.3 is the proper version of the software. And it reports
that the printer is not on just fine. As for having to turn the macintosh off
to stop the driver if it is hung. I have always found that the command period
key will stop the macintosh from triing to find the printer. Every time that
a command period hasn't worked I have been able to trace it to a different
problem in the way the macintosh was set up, both software and hardware.
All in all I would say the disk and ROM upgrades are a good deal, out here in
california they are fairly cheap and you get a significant preformance increase
for a rather low price. I haven't meet anyone, until now, that didn't embrace
the upgrades and new ROM's with a sigh of relief. If anyone has a problem with
their macintosh they should goto the dealer. Obviously the dealer in this
situation isn't very good and doesn't hire 'good' sales people.
As for buying an IBM instead of a Macintosh, well I feel everyone should get
what they deserve.
Note: Go to an IBM dealer and tell them that you would like to new High
capacity drives, the new BIOS in the IBM AT, and have over 95% of your
software run without modification, and you would like all of this for
under $300.00. Watch them laugh!!.

"Why are MAC/SCSI disks so expensive?
Here are some current prices for AT compatible Hard Disks
Seagate 4026 -- 20MB: 39 ms av. access time $528
Seagate 4051 -- 40MB: 39 ms av. access time $680
Seagate 4096 -- 80MB: 28 ms av. access time $1195
AT Hard Disk/Floppy Controller $170
External Chassis & Power Supply $100
These prices are retail and they represent a reasonable profit
margin."
But wait just a second! That Seagate 20 meg hard disk is $528, PLUS a
controller, PLUS a powersupply and chassis. That total cost is $528 + $170 +
$100 = $798.
You can buy a Macintosh 20 meg SCSI for about that much, and usually for
less. And they do not require an external chassis or controller, since the
Mac Plus provides the SCSI controller.
I can't comment on the larger sizes, since I haven't seen any prices...
One might well ask: "Why is the AT such an expensive boat-anchor?" 8-)

Alex,
You might be interested to know that Apple's HD20sc is in fact a Seagate 4026.

Jasmine offers Seagate drives for the Mac (SCSI hard disks), at prices near the
AT prices you quote: if prepaid by check/M.O., here are Jasmine prices:
20 MB: $575
80 MB: $1380 (sub-30ms av. access time, they claim).
They said they also plan to sell a 60 MB drive around the beginning of Jan.
I havent bought one yet, but I've seen one and they seem sound and not
excessively loud (they have fan and surge protector).
The only reason I've waited till now: they told me they are expecting to be
getting quieter drives (disks?) from Seagate, but "Apple keeps snapping them
up before we can get them", they say. Anyone know about these alleged new,
quieter Seagate drives/disks?

The question was placed in a recent InfoMac about the compatability
of the Thunderscan power adaptor to the Koala MacVision unit.
I haven't located Koala recently, however
my local Thunderscan/MacVision expert reports that they both
work just fine with the Thunderscan auxiliary power supply for
the Mac Plus.

Subject: Re: Mac Engineering
Maybe this is something for the "desktop engineering" category too: someone
told me that Digital is doing a lot of work on workstations for engineers.
But because of the long time it is taking them to get actual products on the
market, they have - or so I heard - decided to offer Macintoshes with specific
software for the time being.
The software is supposed to be called 'DECmate' and runs on a Macintosh. As
far as I can imagine this can only be a sophisticated terminal emulator - maybe
with VT220 (or greater) emulation - with possible file transfer. But I really
know nothing about it.
Has anybody here heard anything about this product? And now that we're on the
subject, what's coming out of the agreement Digital and Apple signed some
time ago?

Subject: A note about BinHexing...
I've just noticed why sometimes BinHex doesn't work. When the message
that precedes a binhex'ed program contains a '#' character, binhex gets
sick and dies (No checksum error).
Sometimes I forget to clip the top part of the message,
and once on a Mac it is sometimes impossible to find enough disk/memory
space to edit it. I believe that David alreay strips out colons and
a few other punctuation marks but he can't get everything.
Recommendation: DON'T USE # IN YOUR DESCRIPTIONS!!!

Subject: Imagewriter II problem...
I was trying to print some diskette labels but ran into a problem that
caused my printer to jam. Since then, it doesn't seem to be printing as
well as it used to. I hope not, but the printing head might be a damaged.
Also, the plastic infront of the head has some sort of an aluminium foil
that is also damaged. Being a student, I don't have the resources to take
it to the local dealer (who I don't trust anyway) to fix it. Any idea of
where those two parts might be available and how much they would cost? It
is a simple matter of replacing them.
I appreciate any help.
Incidently, does anyone know of any BBSs that have job listings? I'm going
to graduate in about three weeks with a degree in Computer Sciences, and
still haven't had any job leads yet. Thanx again.

From: werner@ngp.utexas.edu (Werner Uhrig)
Subject: updated directory of NGP-archives available
Some time ago, I announced that I had created a directory listing of the
Macintosh-related files available to ARPAnetters with FTP from this site (NGP).
in file "ftp/public/ngp_ftp-mac.dir"
I just realized that my UNIX-ignorance had me create this directory listing
in a way which only listed the first level of sub-directories but did not
list the files in the deeper directory-levels. Well, it probably isn't
very important, as those subdirectory are mostly self-explained by their name,
but I just wanted to let you know that I'm now making available a "more
complete" directory index in file "~ftp/public/ngp_ftp-mac.subdirs".
Let me explain again how you get to those goodies (*IF* you can access NGP
with FTP):
1) with FTP open a connection to ngp.cc.utexas.edu (formerly ut-ngp.arpa)
2) login as user "anonymous" and any password (courtesy suggests using your
*REAL* userid - just in case you manage to bash something accidentally,
and we'd like to get in touch about it to find out how it happened)
at this point you are then connected to the directory ~ftp which has
several sub-directories, one of which is "mac" where the 'goodies'
are archived and which has many subdirectories, the other one is
"public", where I stored the directory-listing of the contents of
directory "mac" as file "ngp_ftp-mac.subdirs".
3) I do not recommend that you do a directory listing with commands "dir"
or "ls" as that, usually (for me, at least), results in listing not
only the current directory level, but all subdirectories also, which
takes an awful long time and is often quite difficult to stop from
a remote site (which is why I make the directory-listing file available
to you in the first place - because it's "cheaper" to just get a copy
of it, both for you and for us)
4) next, get yourself a copy of my 'directory-listing-file' with the command:
"get public/ngp_ftp-mac.subdirs"
or, if your FTP and file-naming convention has troubles creating
a similarly named file, first connect to the subdirectory "public"
with the command your FTP provides (probably either "cd public" or
"connect public" and then do the get as follows:
" get ngp_ftp-mac.subdirs"
5) once you know which files interest you, you can "get" them from the
respective subdirectory under "~ftp/mac/....". If I remember right,
NGP's FTP supports "multiple get" ....
Please note, that my site-administration (*AND* I) frown on having machine
cycles used for "fun-and-games" FTP-access during office hours, at least for
*MASSIVE* transfers (nobody minds a "quicky" (-:) and that we have *SERIOUS*
intentions to clean up these archives and throw away 'outdated' and 'frivolous'
stuff "any day now" .... - if I'm around and think of it, I'll update the
directory file at that time, of course; but ....

I noticed in internet's advertisement in the December issue of
MacWorld (p. 54) that there is a demonstration version of the intermail
product available on the CompuServe and GEnie networks. (internet's
intermail product is described as electronic mail software for
Appletalk networks that supports internetworks, bridges, and multiple
zones.) Has a copy of the demo version made its way to anyone on the
MILnet/ARPAnet or, preferably, into the info-mac archives? (I'd
rather avoid paying the $10 fee for the demo disk.)
Thanks in advance for any leads,
