Thanks for the plug! I'm not sure which article you mean, one of the cables
notes articles? That type of thing appeared in both the Fall '85 and ZSpring
'85 BMUG Newsletters. For people interested, BMUG sells back issues of its
NL's for $18 each, including a disk.
BMUG now has a MIDI SIG, "Computer Music Users Group" (CMUG), that
meets occasional Saturdays. For moe information, contact Tony King,

I have had similar experiences with Boston-area computer dealers. The old joke
is "What's the difference between a used car salesman and a computer salesman?
The used car guy _knows_ when he's lying to ya'" Anyway, there are a few
reasonable salesmen in the area. You can't find them by going to a specific
dealer, as most dealers I've encountered have both bad and good salesmen. I'm
currently dealing with Neil Greco at Sherman Howe in Newton, who has been
relative open-minded and helpful. I think it's useful to get a bunch of
knowledgable Mac people going to the same reasonable salesman, as he/she can
then get a better feeling for what our particular type of customer needs and
wants -- and can offer. Good luck. - Ric Ford

Subject: 128K ROM/keypad bug
Date: 18-MAY 21:31 Mousing Around
I just ran across a Usenet message that corresponded to a bug I'm experiencing.
To ron@aicchi.UUCP (Ron Spizzirri):
Ron,
I experienced the same bug with the keypad/keyboard on my Mac 512K
after upgrading to the 128K ROMs. Now, after booting, the first
character I type is ignored if it's typed on the keyboard. If I type
the first character from the optional keypad instead, it goes into
auto-repeat mode. Looks like a bug in the new ROMs in combination
with the old keyboard/keypad.

modification comes with a 20" custom display it gives a full 1000x1000
resolution at the same pixil size as the regular mac scre screen. it
also has the ability to output to a projector at that ratio or a
standard vidio (VHS standard VHS..BATA home TV monitor ratio .. this
is a software modifiaction so there is a screen enlargement in the
final result.. This company gives a co-processor (6881) and hard
drive(20 meg) and memory upgrade .. the Hyperdrive of the west coast
with more on the board.. hope this helps open to more...

According to a recent letter from Apple, the Software Supplements are being
renamed to avoid confusion. Instead of naming them "Month Year Software
Supplement", the new terminology will be "Volume N Issue M". The following
table shows the corresponding names:
May 1985 Volume I Issue 1
December 1985 (two shipments) Volume I Issue 2
March 1986 (not released yet) Volume I Issue 3
Developer Tech Support also has issued the following warnings about the files
that were part of Volume I Issue 2:
System 3.1.1 was issued with an Installer set up for 3.1, so the Installer
doesn't work (this has been widely known for some time).
Font/DA Mover 3.1 is not compatible with the combination of 128K ROM
and a System of release level less than 3.1; it can cause damage to
the System file if used in that configuration, so be sure to use 3.1
or higher System release.

Subject: MacServe...
Date: 21-MAY 20:34 Macintosh In Fact
I have received and tried Macserve at our store and I would like to give my
opinion about this product and some reviews about it
Macserve comes serialized (more on this later) You can use just about
on any Hardisk including apple HD20 some hardisk that I've tried are
Lodown , Aplle HD 20, and HyperDrive 20 You can as ussual hook up ,
upto 32 devices on the network (Appletalk limitation) one or more
Host/Server can be configured ! but each one server (not the node
user) has to have their own Master ( because they are serialized) they
will not work if two server with the same serial # are online.
Installing it it's pretty easy just run the Mac serve Install program
from the master and select the destination valume, once you do that.
the server can create partition from the Hardisk, and only this way
that you can share the partition with other users, (Hyperdrive Drawers
can not be shared, unlike Tops) The first time you create the
partition with the Manager , it will be a MFS Volume, but you can
change them to HFS by Erasing the volume on the finder ! Note that
you have to create a boot disk for every Netuser that's going to be
sharing the Network, you probably will find a little difficulty in the
400K Drives, if you are going to use them with laserwriter, because
the system can be really BIG, (with all the laserwriter fonts,Driver,
etc...) it might not be enough... 800 K Disks are OK, so 512K's that
isn't upgraded, has to have a really a squeezed out system.
Once everything is setup, the Host Server can released the partitions
to be used by other users, once a user grab(Make private) a volume the
other user can not have access to it, untill that user released it. if
a partition is shared everybody can have Read Access but the Parttion
is Locked (write Protected) this is a problem for some application
like MacPaint (MacPaint will not work on a locked disk)
Speed: on a Apple HD20 the speed is very slow (we all know) when it get to more
than 2/3 users than it became unbearably slow. on a Hyperdrive is reasonable 3
users can use them together with a little delay in accessing the drive. on the
LoDown is better.
I like MacServe although I'd like to see some improvements, like you can share
the Non Partition Volume (Like TOPS) etc.. Probably the most limitation is
appletalk's speed, but for the price, and if speed is not a problem the program
is useful !

Information from May 19, 1986 issue Computer+Software News:
(headline like) Apple Begins Manufacturing Johnathon
Actually the article goes more in depth concerning the possibility of
Apple selling the IIe and IIc through mass-market merchandisers (read
Toys R Us, etc.) Still, it give some basic information about the
Johnathan (while leaving out some of the best items....
According to the article, Apple has just started production on the new Mac,
which features 68020 and a 68881 co-processor, up to 4 meg RAM, DS internal
drive, black & white screen (no size mentioned!). Also, folks "close to Apple"
said the unit would probably come out in several models with other features
included with some (hot news, eh?). The only real surprise in the story, to
me anyway, was a list price of $2495, with the unit's introduction and first
availability as "late fall". One source indicated that the new Mac would be
a real challenge to the IBM RT .

Reply to: seth@ucla-cs.ARPA (Seth Goldman) I don't see any obvious
reasons why DA's would fail, but the fact that the problem got worse
when you tried to use the Control Panel suggests that your Parameter
RAM is messed up. It might be worth a try pulling out the battery for
5 minutes with the Mac switched off to reset the PRAM.

The freeze upon pressing the Interrupt button will most likely occur when ANY
powered-on modem is connected; I'd guess the more precise condition is any
device asserting the CTS signal (HSKi pin). The cause is a ROM bug.

The easiest way to make a PICT resource from a MacDraw Document is to
select the objects you want to include, copy to the clipboard, and
paste into the Scrapbook. The resource can then be copied from the
Scrapbook file.

Can someone explain to me the "simplest" use of the list manager? That is
displaying a list of character strings. Specifically, where does on store the
array of strings to be displayed and how do the list manager calls access these
strings? IM talks about "theProc" as the LDEF resource ID, yet
an examination of the LDEF=0 shows no way to get a string in there (except in
hex) a'la a DITL in a dialog. ANY assistance would be greatly appreciated

I seem to recall someone asking about optical disk mastering or interactive

line of any of the messages which originated here. The person asking said he
read it in a magazine and couldn't remember which one. Well, the May 86
MACazine has a short review of MacVideo and Mentor which would be of interest
I'm sure.

Subject: Purging HFS Desktop
Date: 25-MAY 05:46 Bugs & Features
PurgeIcons wasn't really designed for HFS, but you can fool it into purging an
HFS desktop. It's using a standard file selection box to select the Desktop
file, but the list of files is hidden from view. Therefore, it's rather like
you're trying to select the Desktop file in the root directory while wearing a
blindfold.
(1) Make sure the current directory that would be displayed (if it
were visible) is the root directory -- not a folder. You can either
click the drive button to select another mounted volume (e.g., floppy)
and then click again until you get back to the HFS volume you want to
purge; or, on a Plus, press clover-uparrow several times to get back
up the folder chain to the root.
(2) Now the invisible file list contains the folders in the root
directory, and the Desktop file. Of these, the one that is
automatically selected by default -- whose name would be white on
black if you could see the list -- is the one which comes first
alphabetically. Usually, this is not Desktop. So select the Desktop
file by typing "Desktop" fairly rapidly -- no long pauses between
letters. Or just type as many letters as necessary to select Desktop
from among the folders in the root directory whose names may begin
with the same letter(s).
(3) Click the Purge button. If you get a watch cursor for awhile, you know you
succeeded.

Subject: RE: Purging HFS Desktop (Re: Msg 8460)
Date: 25-MAY 15:53 Bugs & Features
How come you have to select the Desktop file explicitly? Isn't it
sufficient just to get to the root directory in the HFS hierarchy (I
haven't tried this). After all, you don't have to go through any
mumbo-jumbo when you run it in a MFS volume, even though there may be
files alphabetically prior to the Desktop.
If the problem is (on the other hand) that the WDRefNum is not in the
SFReply record if a folder is selected instead of a file, then this is
only a problem if there is a folder that appears first alphabetically,
rather than a file (any file will do, not necessarily DeskTop). I had
some difficulty in extracting the WDRefNum when I needed it recently,
and the solution was posted by Marsh Gosnell in a recent Usenet post
(involving SFSaveDisk and CurDirStore and the use of PBGetWDInfo).

This is *not* a feature of the USR Password... it's because the modem was still online when you pressed the interrupt switch. If carrier is present, there should be no problem... it's only if a modem is on and *negating* the CTS signal (not asserting it). When no modem is connected, or when it's off, the pin "floats" to CTS. When a modem is on but no carrier is present, it is driven to /CTS, causing the "hardware flow control" in the serial driver to wait for CTS (which it is supposed to do; it is not a "ROM bug" at all). The exact same situation happens if you open the serial port on a plain 512K Mac with the old ROMs and then try to write to it, without disabling hardware flow control. Maybe the debugger should have assumed no flow control for its initial state. [As a side note, actually the CTS pin on the external connector has to be driven negative before any change occurs on the output of the line receiver... back when I was designing my MIDI interface for use with DMCS (described a month ago in net.music.synth) it took me a good while to figure that out. Of course, that follows when you think about all the above, but when you are using the pin to clock the UART (its other function) it's easy to forget... so if you use the pin for clocking, the clock pulses have to go negative with respect to the ground pin for them to do anything.] -- E.
