Subject: TCP/IP for macintosh?
We are planning an Ethernet based TCP/IP network to link several of
our mainframe and micro-computers and we would like to include some Macs.
Does anyone know of TCP/IP software and/or Ethernet hardware for the
Macintosh? If you do, please send me any information that you can, even
just the company name would help.
Please send any comments to me rather than to this digest; digest
reception is erratic out here on BITNET.

P.S. I am sending this to a couple of digests, my apologies to anyone who
sees it more than once.

Subject: Bi-Directional Imagewriters...
As I found out, some Imagewriters will start printing bi-directionally
by caps lock-shift-option sequence when clicking on the print button
in the print dialog box. The sequence used again will put it back into
single direction mode. Supposedly, this will make the Imagewriter print
at almost double it's speed. My problem is that when I tried this
sequence, it did indeed work, but the next time I printed again, it went
back to the single direction mode. Anyone know how to make it stay in the
bi-direction mode?
Another little question. Is anyone out there interested in SmallTalk-80
for the Mac? I've got a version of that from Apple, but have been a little
limited in my operations with it so far. Mainly because I'm trying to learn
it myself, and because they recommend a hard drive with almost 3.5 meg
allocated to SmallTalk (it comes on a 6 disk set). Sheesh|||| Can't wait
to get a hard drive (when I can afford it), but I'm interested in
exchanging information with others who are interested in SmallTalk-80

From: Kathleen Huddleston <gregory@ICSE.UCI.EDU>
I have upgraded my Mac with the new ROMs and new system (3.2). I also
am using a HD20 in addition to the 800K drive. Do I need the HD20
driver in my system folder on the Hard disk, or is this already
bundled in the ROMs or System 3.2? Also, I have heard that AppleTalk
is in the new System and new ROMs. Therefore, do I need the separate
Apple Talk driver as well? While I'm at it, do I need the software
version of the Chicago font in my System Font file?
If I can remove any of these, it would be nice to do so.

Subject: Re: Digitizing point coordinates (MacTablet)
This letter discusses using Mac compatible digitizing tablets to get high
resolution data into the Mac.
This is very easy to do with the Kurta tablet. With the Kurta tablet you can
map a small area of tablet onto the screen, so that the digitizing pen
will cause the mouse to move in sufficiently large increments to give you
the resolution you want. When you want to digitize another area of the tablet,
you use a desk accessory to load a new configuration file, and the tablet is
automatically remapped.
Since you are stuck with what you have, and since you are not afraid to
program, you might try the following:
I assume the MacTablet connects to the Mac using a serial port.
Do not use the MacTablet software.
Listen to the tablet using terminal software (Versaterm, naacterm ...)
(try 9600 buad as an initial guess at the baud rate.)
The tablet probably sends a 5 byte data packet of the following form:
b7 b6 b5 b4 b3 b2 b1 b0 - bits of a byte
P 1 0 0 0 S 0 0 - P is parity. S is on if switch is down
P 0 x5 x4 x3 x2 x1 x0 - low 6 bits of x data
P 0 x11x10x9 x8 x7 x6 - high 6 bits of x data
P 0 y5 y4 y3 y2 y1 y0 - low 6 bits y data
P 0 y11y10y9 y8 y7 y6 - high 6 bits y data
b6 is 1 only at the start of a 5 byte data packet.
This data is drawn from a Summagraphics data sheet for their Bit Pad 1
digitizer.
Unlike the Mac, point (0,0) is probably at the LOWER-left corner.
If you get data that is consistant with this, then you need only write a
basic program to read data the serial port. Tablets generate so much data
that you're program had better check the fullness of the serial buffer and
throw away 5 byte data packets periodically to keep the buffer from
overflowing. Alternatively, you could write in a langugae, like C or
compiled Pascal, that was fast enough to keep up with the data rate.
Low-resolution Kurta tablets and
other-than-MacTablet Summagraphic tablets use this data format when they
are not transmitting data is strings of ASCII, base-10 integers.
Kurta's PenMouse, a cordless digitizer considerably cheaper than
MacTablet, sends 2400 baud, their other models generally run at 4800 baud.
Kurta also makes a MacXL compatible version.
Disclaimer: My opinions are solely my own, but, in evaluating them, you
should know that I am currently re-writing Kurta's software.

Subject: Help with Font Changer Improvments
First off, I would like to thank all of you who assisted me
by reporting bugs that you found in Font Changer. It's
pretty much common knowlage now that the scroll bars are messed
up, but I'm going to fix that. (For now, restrict your changes
to the uppermost fonts, those you don't need to scroll to.)
I have a new program in the works, called Ruler Changer, that
will allow global changes on ruler formats. (We have lots of
people here that write theses and then realize afterwards that
they need wider margins) It should be finished and posted
in 2-3 weeks. (The basic program is pretty much finished,
but the ruler animation and interface is still a little flakey.)
My next task after that is to combine the two into one grand
monolithic document mangler that will allow global font/ruler
changes, plus whatever else I can think of. SO.
I am going to add the following:
1) A count of the number of paragraphs changed.
2) A place for you to type font numbers in yourself, for
changing documents that are in a font you don't have.
3) A way of checking what font numbers are in the document
itself, helpful for using the above option.
4) Word compatability if I can get the format.
5) Will only have to select the document once, and will be
able to switch which document to change without exiting
the program.
6) Ruler Changer additions:
Global search/change of ruler:
a) Margins
b) indents
c) tabs
d) spacing
e) formatting
7) And an oldie, but a goodie, fix the scroll bars.
Anyone out there have any suggestions as to what else would
be nice to see? As the world's shortest MacWrite user, I
find it hard to think of problems w/ huge documents. Anything
would be helpful, and as before, I'm still looking for a
Microsoft Word format that will let me add that feature
to the program. Character type conversions are probably out,
such as upper/lower case conversions and style changes to
certain words, but anything else you can think of would
be a major help, I'm always open to suggestions.

Subject: Large-screen projection systems
Does anyone have any experience (good or bad) with flat large-screen
projection systems for the Mac. We have seen several demos of displays
and have been quite disappointed with the quality of the image. (We will
have a class of 60 reading displays constantly during a one hour class).
The biggest problem seems to be contrast between text and background.
Our ideal system should be able to display images from Macs, IBM PC's,
VCR's and Video Disks (in color for these last devices). The price should
be in the range between $10K and $25K.
Thanks in advance for any help you can provide.
