Subject: additional memory in SE's
Generic stupid question that I can't seem to answer:
We've just added 2Meg upgrades to our MacSe's here. That's
2.5 Meg total memory. What improvements can we expect ? In what applications? I know Multifinder will run better, but where else is it noticeable ?
Where should I set the RAM cache ? (64K ?, 128K?) What will that actually
help ? Please mark actual experience versus informed hypotheses (I know
what it should affect, but should is a vague word.) Will going to 4Meg
make any noticeable difference ?
Please reply directly to me and I'll summarize to the net in a week or two.

Subject: Canvas 2.0 Arrows
Canvas 2.0 now has an Arrow Manager which not only lets you choose between
three different types of arrow heads, but lets you reshape them as you like
(e.g., make them longer, shorter, fatter, thinner). You can also have it
automatically put end-lines on the arrows (as is used normally for dimen-
sioning things).
Canvas 2.0 has a HUGE list of other features. I have a 5000 character file
detailing all the goodies if anyone's interested. It really is the best
drawing program on the planet. And soon it will be even better. Current
plans call for adding true dashed lines and WYSIWYG text wrapped around a
curve (!!!).
Let me know if you want any more info...

Subject: Collaboration among Macs and Apollo workstations?
Does anyone out there use both Macs and Apollos and make them work
together? I am part of a group that has both. We would like to:
1) print from the Apollo on the Apple Laserwriter; 2) use the Macs
as terminals for the Apollo, with multiple windows and graphics if
possible; 3) use Apollos as file servers (possibly, but less important.
I am on the Mac side of this, and don't know much about Apollos.
The LocalTalk network of Macs and Laserwriter will be connected
to Ethernet along with Apollo cluster; Macs could also be connected
by serial lines.
CAP (Columbia Appletalk Package) should accomplish 1) and 3) for
UNIX (4.2 BSD), but apparently has not been ported to Apollos.
UW (in the Info-Mac archives) evidently provides 2), but only
over direct serial connection, and I don't know if it has been
ported to Apollos.
Any users of Apollos who can enlighten me? Any users of UW, on
any system, who can report experiences?
I'll summarize for the net any responses I receive directly.
Thanks.

According to the System Errors DA, 42 is shutdownAlert, which is cryptically
described as "handled like a shutdown error". According to IMV-586 the way
things work is that the Shutdown Manager looks at your machine type. If you
are a Mac II it shuts off the power, otherwise it sends the System Error
Handler a 42 (of course ;) and it puts up the dialog that says "It is now safe
to turn off your Macintosh." Obviously something is missing, either from your
system or memory, and so it is putting up the bomb instead. Perhaps someone
has skagged the resources necessary in memory. It will obviously take some
digging to find out why this is occuring unless someone else has seen this and
has an explanation as to the reason it is happening.

After reviewing the discussion about the hard disk partitions, I've decided
that's the route I need to take.
My question is where do I get the software necessary to partition my disk drive?
It's an Everex Emac-20. The utilities included with it do not include anything
resembling partitioning software.
After suggestions would be appreciated, especially if the software is public or
shareware.

Subject: Mac graphing, Laserwriter IISC questions (2)
I have two Macintosh questions that I hope I can get answered.
First, I would like to obtain a graphing software package for the Macintosh. I
am mainly interested in creating 2D x-y graphs. I am not familiar with any Mac
graphing packages except MockChart, which is not acceptable (can only read data
>From Clipboard, only plots whole numbers, ... blah!). I would like to hear
>From people who have used Mac graphing software. What's good? What isn't?
What is priced right (or better yet, is there any good PUBLIC DOMAIN graphing
Mac software available)?
Second, a client of mine recently purchased a Laserwriter IISC. Most of the
time, it prints great. However, sometimes text that is in a file and on the
screen doesn't print when printing in landscape mode. I don't know if it's the
printer driver, the application, or the printer (I don't think it's the
printer, but I could be wrong). Has this happened to anyone else out there?
I would appreciate any help I could get.

Subject: Macs directly on Ethernet
Greetings from the Bitnet side! Recent questions about the AppleTalk to
Ethernet connectivity problem prompt me to comment about our project, where we
will be connecting Mac II's directly to Ethernet with a MicroVAX II (and,
potentially, other VAXes).
There sure seems to be a dearth of literature (and products!) for this
style of connection. There are lots of products, obviously, for the AppleTalk
to Ethernet world, since 1) That's been the only way to network Macs to other
folks for so long and 2) only recently have we had Macs which could accept
a direct Ethernet connection/adapter card. So, the AppleTalk to Ethernet
market is pretty rich in hardware and software products, with more on the way,
I'm sure.
Since the University of Cincinnati has a heavy investment in DECNet-linked
VAXes, we want to basically run DECNet-or-something-like-it or something-
compatibile-with-it on our "local" Ethernet. We also want to "bridge" over
to the rest of the University's network, isolating traffic one either side
except that which is specifically destined for a node across the bridge.
We hope that will keep general OA-type traffic on their side, our medical
and patient-specific traffic on our side, and (if we get to it) potential
encoded-video data on our side, so it doesn't compete with the OA/etc.
traffic in the "big" network.
We are in the process of looking at products like Pacer/etc. and CommUnity,
but would welcome comments/suggestions about other DECNet-like or DECNet-
supporting protocols to run on our network, as well as comments about the
bridging options we should entertain. Conversely, I will be glad to share
with the net or with individuals information about our trials and tribulations.
With that offer, let me bring this overly long msg. to a close :-). Thanks
for your support.

Subject: Probs with Mac 512
We've got a Mac 512 (unenhanced) that is having a bit of a problem. It passses
the self test perfectly. After inserting a disk you get the Happy Mac. After
about 5 seconds (before the "Welcome To Macintosh" startup screen) we get
a Sad Mac Icon/Black screen with the codes 0F 0064.
It seems to me that it wouldn't be memory related, since that would be checked
at startup. Does this mean drive or drive controller?
Thanks for your help

An excellent Cyrillic (Russian) PostScript font is available from Linguists
Software which is commercially available. It is called LaserCyrillic. One
problem with LaserCyrillic is that it is not mapped to the keyboard as a Soviet
keyboard would be, nor can it be alphabetically sorted with programs like Word.
A professor here has developed a remapping of this font which solves these
problems. You must have the LaserCyrillic font for the remapped font to work.
I will post a copy in a separate posting.
Several other imagewriter Russian fonts exist as well.
Check the Macintosh Buyer's Guide.

Subject: SCSI disk/copier/fixer
I have a SCSI Jasmine disk with a trashed Master Directory. I would like to
make a complete sector for sector copy of this disk to another identical model
and then I would like to try to replace the bad Master Directory with
the backup copy.
Does anyone here know of any software that will let me perform both of these
operations even though the file system will not mount the disk?

Subject: SCSI partitioning for Seagate 277N drive?
After several people kindly pointed out the advantages of partitioning a
hard disk into smaller volumes, I tried to do this. The installation
software supplied by the manufacturer had no partition option, but I was
able to use a modified version of the Apple HD SC Setup. But its custom
partition option allows at most one Macintosh HFS volume.
Is there any other way to get true SCSI partitioning on this drive (ST277N)?
(I already know about the pseudo-partitioning offered by Symantec
Utilities.)

Subject: Serial Pinouts and Cable Information for MacII/SE
I am posting this to comp.sys.mac. You might be interested in it for
the archives.
- Glenn Trewitt
Pinouts and cables associated with the modem and printer ports:
>From the Macintosh II Owner's Guide:
Viewing the pins on the end of a connector on a cable:
6 7 8
3 4 5
1 2
Note that pin 4 is actually offset a bit to the left of center. The
Apple manual shows the pinout on the plug on the back of the Mac and is
therefore reversed from this.
The signal assignments are:
1 HSKo Handshake out
2 HSKi Handshake in / external clock
3 TxD- Transmit data -
4 GND Signal ground
5 RxD- Receive data -
6 TxD+ Transmit data +
7 GPi General purpose input
8 RxD+ Receive data +
On the modem port, GPi can be set to be a second external clock.
Note that by making a mirror-image of this pinout, exchanging
(6,8), (3,5), and (1,2) you get a null-modem. (Except for pin 7.)
*** This type of mistake is easy to make, so watch out! ***
The standard Mac Port to modem cable is as follows:
(Mini-8) Mac RS-232 (DB25P)
Port DTE
-----------------------------------------
1 HSKo DTR 20
2 HSKi CTS,CD 5,8
3 TxD- TxD 2
4 GND Sgnd 7
5 RxD- RxD 3
6 TxD+ n/c
7 GPi n/c
8 RxD+ Sgnd 7
Pin RxD+ is grounded to make the differential RS-422 signals
compatible with RS-232 signals. This cable produces a Data
Terminal Equipment (DTE) interface which is intended to be
connected to a Data Communications Equipment (DCE) interface.
DTE interfaces are usually on a DB25P connector (with pins).
DCE interfaces are usually on a DB25S connector (with sockets).
[ Note about RS232 signal names: The signals named TxD (transmit data)
and RxD (receive data) are from the point of view of a Data Terminal
Equipment (DTE) device. For a DTE, data will come out of TxD. For a
DCE, however, data will go into TxD. It's very confusing. If in doubt
about which direction data should be going, get out a voltmeter and
measure from pin 7 (ground) to the pin in question. You will measure
a voltage larger than +3 V or less than -3 V if a signal is being
driven on the pin. If the voltage is near ground or high impedence, it
should be receiving a signal. Better than that is a breakout box,
preferably one with two-color LEDs that can indicate >+3V, <-3V, or
floating. ]
To make a null-modem version of this cable (e.g. for connecting
a printer), just exchange the input and output signals:
(Mini-8) Mac RS-232 (DB25S)
Port DCE
-----------------------------------------
1 HSKo CTS,CD 5,8
2 HSKi DTR 20
3 TxD- RxD 3
4 GND Sgnd 7
5 RxD- TxD 2
6 TxD+ n/c
7 GPi n/c
8 RxD+ Sgnd 7
WARNING:
I have seen DIN-8 to DIN-8 cables in two varieties. One
connects pin 1 to pin 1, 2 to 2, etc., and the other that
exchanges (1,2), (3,5), and (6,8), making a null modem. This
is a deplorable situation, but itUs AppleUs fault for not setting
a standard. I prefer to use the straight-through cables, since
other devices, such as A-B printer switches, use the same scheme.
Having a null modem appear out of nowhere is very confusing.

Subject: System Error 42
This code appears in the System Errors Table 1.8 desk accessory as:
42 shutDownAlert handled like a shutdown error
I _think_ that the standard shutdown code issues a system error 42,
which is trapped by the system error handler; the error-handler puts
up the "You may now turn your Mac off safely" message rather than the
standard bomb-box.
I'd begin to suspect that while "student proofing" the machines, you
might inadvertently have removed too many resources, leaving the
error-handler unable to locate the appropriate alert-text.
