Autocopy compiles but it doesn't work as expected. It says h/filename
'not able to write'. Does anyone know how to fix this problem?
Comments are appreciated.

Got this in the mail and thought it would be of general interest.
In case you missed it, this is a response to my article on the 3.5"
DS Epson drive upgrade for the SF354. There is a problem with the
non-boot drive (B:) not being recognized by the system unless a disk
(even a blank one) is in it.

OK, any ideas? How about just shorting out the disk in

The version if Gdos that we recently received from Atari does indeed
allow multiple font loading (from any directory), etc. One thing that i was
rather surprised to find was that Ataris version of Gdos does not support
NDC coordinates (Landon/Neil can you shed some light on why ??). In any case
i feel NDC coordinates are quite useless, and what would be more usable
are user defined world coordinates (only metafiles support them), that
Gdos converts to RC in the appropriate way so that drawing primitive still
come out right (at least on the screen??). Also NDC coordinates are quite
useless in Gem as AES does'nt use them anyway. Can someone from DRI/Atari
explain why AES was designed in this way (rather why Gem was half done??),
or were NDC coordinates added into Vdi as an after thought??

if you're going to look for ways to cheat, you might try looking in
the executable for the rogue's name (i.e. what you type in for the

literally right there in front of you in the code. nuff said..

To the person who asked about 'zooming out' in the zoom mode of
Uniterm: in the zoom mode, 'Backspace' will restore the previous scaling
factors, and 'Return' will leave zoom mode. Also, the arrow keys will move
the screen 1/10 of the screen width/height in their direction (in the zoom

Mark,
I am also a part-time musician and a full-time computer engineer.
I have two synthesizers and a drum machine that I have had MIDIed to
my ST with no problems. The ST seems to be an excellent choice for this
type of application. Some of the projects I've been working on are a
patch librarian and an Artificial Intelligence based patch generator.
I've also experimented with a single track MIDI sequencer, but nothing
very complex.
> What is a good language to use? I assume C is the best, but which one?
> Can Megamax C be used with the MIDI ports?
I use Megamax C to do my MIDI programming. I've found the inline assembly
feature to be very valuable when try to optimize sections of code for
speed, a necessity in real-time MIDI applications.

I don't know about this. I would think that the MAC software wouldn't run
though since the MIDI hardware interfaces would be different. I don't
think the cartridge would take care of this difference.

****************************************
Hybrid Arts is feverishlg on the ADAP and associated products (20
Software Applications are slated for development).
ADAProcessor) is our "16 Bit Professional Digital Audio Workstation
generic digital interface, the software determines the application,
that is, ADAP can be a Recorder/Editor, 64 Track Multitrack
Recording System (Recorder, Mixer, Effects, Synthesizer,...etc.),
Test Sets (Spectrum Analyzer, O'scope,...etc.
ADAP hardware specifications are:
ADAP I - is a 16 bit linear, Stereo (2 discrete channels),
+4/-10 dbm in/out, Mic/line at the input, gain trims at the input,
calibrated in/out, with LED metering for in/out for calibration
and monitoring. It has a sampling rate that is adjustable up to
65k s/s (may change up to 100k s/s), and is fully CD compatible.
This version only supports RAM.
ADAP II - Same specs as ADAP I with additional support of
"Direct to Harddisk".
ADAP III - (ADAP III is only speculative) Same as ADAP II,
but with multiple inputs and outputs (up to 6?).
ADAP can sample up to 20 seconds with an unmodified 1040ST. ADAP
tests for available memory, so that, upgrades are taken advantage with
an unmodified ADAP. 4 meg allows for about 1 minute sample time.
The sampler will offer 64 samples key assignable, 6 voice poly,...etc.
The direct to disk versions can record up to 40 minutes or more!
The 2 track editing capabilities are going to be astounding, and ultra-
easy!!!!!!!!!!!!!!!
The ADAP has made its first television and live stage appearance.
The television show was "Chronicles" aired on your local PBS
station during the week of September 29, 1986. Call "Computer Chronicles"
at; 415-574-6233 and ask about the "#403, MIDI Music" segment, or
request transcripts via "Compuserve". Hybrid Arts presents the ADAP and
EZ-Track to the world.
smb: I called the "Computer Chronicles" people and they said the show
would air again during the week of DEC 23. CAll your local PBS station
for the exact time.
The "Pointer Sister's" used ADAP, live onstage before 17,000 listeners.
In the crowd were: Sam Tramiel, Gary Tramiel and other executives from
ATARI, Wendel Brown, Rick Oliver and Scott of Hippopotomus
Software, all invited by Hybrid Arts. Afterf the show the Tramiel's
were taken backstage and introduced to the "Pointer Sister's".
****************************************
Enough of ADAP, EZ-Track is our $65, 20 track MIDI Recorder, with
lots of advanced features that has been shipping for about a month
now. It can be bought through our music dealers and "Mega-
Chain Stores" like Federated,...etc.
DX-Droid for the ST is shipping, it will actually program you DX/TX
modules for you ($244).
CZ-Droid for the ST is shipping ($99), it will program ALL CZ's for
you (even the unprogrammable 230S, that's right! and the CZ1).
EZ-Score for the ST ($99) will be shipping soon, it will chart
out our song files for you (like printing the standard musical notation
for your EZ-Track songs,...etc.)!
SMPTEMate, a universal SMPTE interface for the ST will be shipping
October 1, 1986. This incredible device will read and write all standard
forms of SMPTE and lock up to all other forms of presently used tape
sync (like FSK,...).
All associated manuals can be bought separately.
I called Hybrid Arts and the price of the ADAP I is listed at $1995.
MIDITRACK ST is $375/$575(with SMPTE). Also I know Dr. T's has just
released a MIDI sequencer for $199. With this kind of support, the
has a good chance of becoming THE computer for MIDI applications.

How did you get GDOS from Atari? When I called the other day, they told me
that either I had to pay the $500 licensing fee per product per year, or I
could send my software that didn't use GDOS to them "for testing". I was told
that if I wanted to do that testing myself, I should buy some commercial

Can anyone shed some light on this?

Subject: Re: Micro-EMACS 3.7i -- bugs and comments
To: info-a...@su-score.ARPA
I think some people misunderstood my point about the search string delimiter
key. I'm not pitching for using a machine-specific key like ENTER or
control-RETURN. I would like to use RETURN itself (which is about as
standard as you can get). The point is that given ^Q-RETURN inserts a <NL>
anyway, why not use RETURN to delimit the search string rather than ESC? I
have worked with fairly lay people and nearly all of them find ESC very
non-intuitive. If this is to be an editor for a user-friendly PC for
non-technical people, RETURN makes much more sense as a delimiter (besides
being easier to type). I guess the best thing to do would be to make it
customizable, as a couple of people have already suggested.
The other related point is that ^M should insert a ^M rather than being
coerced to <NL>. Since <NL> is merely ^J, either ^J and ^Q-RETURN can be
used to get a <NL> in the search string.
Finally, for those who haven't managed to bind their mouse, try:
bind-to-key previous-line FNH
bind-to-key next-line FNP
bind-to-key forward-character FNM
bind-to-key backward-character FNK
(I also find it useful to bind the left mouse button to SET-MARK; to do this,
try: "bind-to-key set-mark FNt"). One question though: it is weird to see
the cursor wrapping around when you move the mouse off the left or right end
of a line (again, something I could live with but non-intuitive
nevertheless). Is there a way to define a macro that would not do that, and
bind the mouse key to that? Something like the LOOKING-AT function of Emacs
with some sort of conditional would do it. (Unfortunately, I still can't
RTFM. No-one sent me one. Sigh...)

a floppy disk?
Speaking of running without a floppy, when might we get software to let us
boot off of our hard disks?
While I am on a roll here, is the next version of TOS going to fix the famous

The "test" file is /bin/vi. I have shown the compression ratios for
the various interesting files. A file ending in "pig" is an earthpig
encoded file. A file ending in "uue" is a uuencoded file. A file ending
in 'Z' is a "compress"ed file.
test 131338
test.Z 70103 (0.533 of test)
test.pig 143087 (1.090 of test)
test.uue 180979 (1.378 of test)
test.pig.Z 73175
test.uue.Z 94691
test.Z.pig 96698 (0.736 of test)
test.Z.uue 96611 (0.735 of test)
For compressed data, it does about as well as uuencode. For uncompressed
data it's quite a lot better. Small binaries (under 20K) shrink slightly.
C programs and text files shrink slightly or stay about the same.
Earthpig uses only the characters
+-abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
@.,;:=?*"'/!()_%&
This character set should make it through almost anything unchanged. The
algorithm only uses table lookup: no bit masking or shifting.
When we finish the archiver we will post various versions of it to the
net.
What it does:
- can generate correction requests from errors
- can generate patches from correction requests
- CRC checking on two levels
- supports os independent hierchical file names
- high immunity to format changes and noise characters (space/control)
- close to 1:1 encoding on uncompressed data
The basic goal of earthpig is to provide a single tool that will allow
the transfer of arbitrary data and software around the network while
providing a very high level of confidence that the data arrived correctly.
