*Tim Oren: Tell you what, I don't believe in wasting people's connect time.
If you gotta question, go ahead.
Jeremy(JNL TEK Inc): Tim,which company is making the os9 on for the st?I
saw it at comdex but it wasn't in production yet
*Tim Oren: There are three (!) answers to that question OS9 is written/owned
by a company called Microware The Atari porting is done by a company called
TLM Systems and the result will be marketed by MicroTrends of Schaumberg, IL.
Go ahead.
Jeremy(JNL TEK Inc): is it running under tos or is it an independent as
like say BOS.
*Tim Oren: It is a completely independent OS. By the way, TLM Systems also
sells a 68K add on card for the PC which runs OS9 - I have used it, and it's
quite adequate for development. ga
Jeremy(JNL TEK Inc): When would u predict that we will have CD's with
audio/video/computer with read/write
*Tim Oren: Let me try and break that questions up into parts First,
Jeremy(JNL TEK Inc): and who are the main developers of cd rom's?ga
*Tim Oren: about read/write, Then I'll take the parts about mixed media and
August 23, 1986 CD-ROM CO Page -1-
main vendors. OK. Read/write - Currently there are NO systems (to my mind)
which are viable read/write options for desktop uses. The big 12" platters
are VERY expensive and suited for mainframes. The small 5.25" WORMs perform
worse and cost more than a few 70MB hard drives picked up at a swap meet - or
just buying a Bernouilli box (sp?) for that matter. As to when, it's hard to
say, but longer than most people have predicted. There are some VERY tough
mechanical problems to be solved to get the size and price down. I don't
think small WORMs can succeed as a product until they can replicate the form
factor of the CD, at no more than twice the price (that would be about $1500
to $2000 right now). Second, Multimedia - there is some of this available
right now. You can get a modified Hitachi player from Reference Technology
which will also play audio. CD-I is designed to address this problem
directly but don't expect to see real products for QUITE a while. (I'm
talking end of '87 or later.) Another possibility, which has been around for
years, is to adopt LaserDisc as a sort of LD-ROM or LD-I, with mixed media
storage. As to vendors, I'm assuming you are talking about hardware. The
main companies actually shipping CD-ROM units are Hitachi, Philips, Sony,
Denon and Toshiba (more expected momentarily). Phew, Go ahead.
JIM W: I have a LD 700 Laser Disc, which has a computer port, is anyone
writing software for this
*Tim Oren: The LD700 computer port is for remote control. Yes, there are a
few packages available now that will run it from your computer. It's main
value is to coordinate a video and audio presentation from the LD with a
computer program. (Hang onto that thing I'm aware of a few projects I can't
talk about that will be just killer! ga Joe Pope
JOSEPH T. POPE: have you any experience interfacing multiple cd's to the
st
Jeremy(JNL TEK Inc): hand raised(best way to do this I guess.
*Tim Oren: A moment for an aside, since Dave Groves hasn't made it yet. If
you want to ask a question, just send a string of questions marks (5 or so),
and I'll keep a list here of the order received, and come back for your
actual question when ready. So, as of now, Joe is asking, and Jeremy is on
deck, Jim W to follow.
Jeremy(JNL TEK Inc): ?
JIM W: ?
*Tim Oren: Joe, about multiple CD's. I haven't tried this on the ST itself
but it has been done on other systems. Are you concerned about the
performance of the ST, or the CD-ROMs?
JOSEPH T. POPE: any experience the st, dma chip in particular
August 23, 1986 CD-ROM CO Page -2-
*Tim Oren: The DMA chip can handle that situation with suitable software,
because the SCSI standard allows multiple devices. (This presumes, of
course, that you are using a CD-ROM with SCSI capability. They are just now
becoming available.) The economic issue could get interesting, since each CD
setup is now more expensive that the ST itself! It might be more useful to
duplicate the STs that worrying about the software issues! Go Ahead Jeremy
Jeremy(JNL TEK Inc): Where would a cd rom hook up to a st?The Dma port on
mine is used for a hard drive..If and when the octobussy comes out though I
guess that will handle the problem. also,what is the average price of a cd
rom,and who is supporting cd roms on the st?
*Tim Oren: OK, in order. The CD would hook up to the DMA port. The SCSI
standard which will be supported there is capable of handling 8 devices (a
computer and 7 peripherals). When that time comes we will see just how well
the hard disk manufacturers have followed the rules!.. On pricing. Drive
prices (at retail) currently run from $850 to about $1500. The plastic discs
used in them COST the manufacturer about $5 to stamp out. But, because of
the enormous cost of preparing that much data, the retail prices range from
$200 on up to tens of thousands for a yearly subscription service... CD on
the ST: To my knowledge, Atari's plans to market a Cd player are on hold
until they can get one at a reasonable price, preferably with audio
capability. I am aware of two companies that claim to have working
prototypes: KnowledgeSet and Library Corporation. The latter is probably
vapor - no one has seen it. KSC determined that the cost to take the drive
and controller to market weren't justified at this time. ga Jim
JIM W: can u say any more about the use of the LD 700 laser disc ? Is
atari working on it are is all 3rd party
*Tim Oren: The projects that I am aware of are 3rd party projects. Sorry, I
can't elaborate, because they are confidential. Just be patient and you will
see some mind blowing things in a year or so.
JIM W: when can I except something to hit the market
*Tim Oren: The year time is my best guess, subject to a plus or minus 6 month
error! (grin)
Jeremy(JNL TEK Inc): ?
*Tim Oren: Go Ahead Jeremy
Jeremy(JNL TEK Inc): Their is a company called hybrid arts(excuse the
August 23, 1986 CD-ROM CO Page -3-
spelling)
Dave Akers: ?
Jeremy(JNL TEK Inc): this company does mostly midi development,they have
a new product that allows you to store a digitized sound on the Atari hard
drive, this sound quality is supposed to be better then that of a CD.any idea
how this can be done?
*Tim Oren: Digital sampling isn't all that hard - it's doing it well that's
difficult. Some people may recall hacks to make an old Apple II "record"
sound fed in via the tape port, and set back out through the keyboard
speaker. Now that's crude! A must better example is the type of sampling
keyboard instrument that you can buy (around here at least) for $110. As an
aside, for those interested in both MIDI and CD, there is a company called
E-mu Systems near here in Scotts Valley. They make a top of the line
electronic instrument called the Emulator, and have just released a CD-ROM
drive which stores enormous quantities of patches in digital form. There is
a very interesting two-way merger of music and data going on. ga Dave
Dave Akers: What is the status of the CD_I spec? Are they keeping the
details 'secret'?
*Tim Oren: The draft Green Book CD-I spec exists (I have seen it). Right now
it is still marked Confidential. However,it does not differ in gross
capabilities from the public description at the Microsoft Convention.
I think you can expect a final spec near the beginning of fall. However,
the full document will probably only be distributed to licensees (that's
$5000 on the table, buckeroo - kinda slows down the little guys.)
sigh. Who's next?
JOSEPH T. POPE: ?
*Tim Oren: Go Ahead, Joe
JOSEPH T. POPE: developing a dma-cdron-hd interface for the st using
Hitatchi 2500 drives. question, why does the st dma line toggle all the time,
seems it should be quiescent when nobody is trying to address something. ga
*Tim Oren: I'm afraid you've got me on that one. I hate to say ask Atari, but
it's all I can do. Do you see this effect on all samples of STs? Could it
be a flakey/misdesigned tristate or something like that? ga
JOSEPH T. POPE: on 3 samples,don't think so, see it on 3 st's, all with
tos in rom ga
August 23, 1986 CD-ROM CO Page -4-
*Tim Oren: Sounds like a live one It's no big secret that the system as
shipped is not really SCSI capable - for lack of software if nothing else.
ga
JOSEPH T. POPE: developing our own drivers and interface, guess we better
check with atari,thanks.
*Tim Oren: Who's next? (Hello to Antic) By the way, you can ask GEM questions
also Joe, do YOU have something to do with Library Corp?
Dave Akers: ?
JOSEPH T. POPE: negative, I'm with PPi Electronics
*Tim Oren: Just curious. go ahead, Dave
Jeremy(JNL TEK Inc): Hi Antic(Gary Yost?)
Dave Akers: Do you know of anyone developing authoring systems for cds or
cd-I's
Jeremy(JNL TEK Inc): ?
*Tim Oren: Yes, quite a number. Perhaps I could narrow down the list if you
could describe what type of authoring you are thinking of (interactive data
entry, full text retrieval, hardware level premastering) etc. etc.
ga Dave, (Jeremy on deck)
Dave Akers: I'm interested in entertainment software (sound, graphics,
etc. The st has the right processor for cd-i, but you obviously need
gigabytes of storage for development.ga
*Tim Oren: OK, taking it from the bottom (hardware) on up There are four major
"data prep" operations in the business right now (though there might be
arguments from others). They are Reference Technology, TMS, KnowledgeSet and
Videotools. The first three are all set up to take input data tapes from
you, and do indexing, formatting and so on, returning a tape which you can
take to a production facility to get a CD made. Videotools instead sells
(for about $35K) a hardware/software device with up to 1.2G (!) of hard disk
plus a tape drive, which allows YOU to make the tape for the production
facility. BUT, that means you have to write your own indexing software. On
to the software. Most of the existing retrieval systems are oriented toward
text, and ALL of them are oriented toward business or reference works. To my
knowledge, there aren't any currently available authoring or indexing systems
that are well suited to mixed mode - that is, computer graphics, animation,
August 23, 1986 CD-ROM CO Page -5-
sound, text all in the same mix. The Philips Interactive Media project is
funding some efforts to develop this. There are number of. companies with
obvious abilities in this direction. I might mention Lucasfilm (Droidworks),
OWL International, Macromind, Apple Computer, and the MIT Media Lab and Brown
University. However, there isn't any "canned" solution that you can buy.
So, you get be patient, or turn into an inventor. (Remember, the way you
tell the pioneers is the arrows in the back) :-)
JOSEPH T. POPE: ?
*Tim Oren: Go ahead, Jeremy. Joe on deck.
Jeremy(JNL TEK Inc): This question is about GEm. We develop 15 different
products for the st we have been asked/told to develop a product that would
allow a split screen on the st,or sort of using a mono and rgb monitor at the
same time for programs that run different data files in different res modes,I
know the st cannot have mono and rgb at the same time but I was told that we
could make it in a way so that the st does not have to reboot after switching
monitors,and that the st would Identify the mono monitor and let u use it,how
is this possible..?ga (sorry about the length of the question)
*Tim Oren: I think I know how to approach the problem (though I've haven't
tried this) The changing of a video cable on the ST normally causes a
hardware interrupt (to keep from frying monitors) Obviously, you are going to
want to do a software switch, because the user won't stand for pulling out
cables. I think you will have to put some hardware in line between the
monitors and the video port, find some output bit to drive it, and cut off
the signals to the monitor not currently in use. Since the switching would
be software driven, you will have to initiate the res flip inside the ST, or
you WILL cook a monitor. That's doable. The big hassle comes when you say
you want to uses GEM that way There is NO way that you can get the AES and
Desktop to gracefully switch resolutions. There are a LOT of global
variables in the AES that are initialized when the system fires up. They
have to be rebuilt from scratch when the res switches. The root problem is a
mismatch of software (GEM) and hardware (ST). GEM was designed to work on
the workstation model inherent in the VDI. That model says that the physical
workstation is a CONSTANT, not something that can change res on whim. So
software-wise, you may be wedged, unless you want to just use the VDI, and
forget the AES. ga Jeremy with any last comments. Joe on deck.
Jeremy(JNL TEK Inc): we've done alot of development with the St's
monitor. I understand what you are saying,I think we will cancel that
project..we do
JOSEPH T. POPE: just a comment: 3-M and Sony also do premastering of data
and disk mastering
*Tim Oren: Right. However, premaster and mastering are processes distinct
from what the industry calls "data prep". The premaster and master set up
August 23, 1986 CD-ROM CO Page -6-
the error detection/correction levels and do bit scrambles. Data prep is
more concerned with taking a batch of data in sequential or hard-disk
optimized form (such as B-tree) and changing it into something that will work
acceptably with the CD-ROM access characteristics. Aside to those who don't
know: CD's are SLOWWWWWWW... We're talking about average seek times in the
quarter to half second time, with latencies in the tens of milliseconds.
Obviously, you don't want to do a lot of head seeks! We're coming near the
end of our time slot. Does anyone have another question?
NEAL KATZ: hello ( I think I'm late )
JOSEPH T. POPE: ?
*Tim Oren: Go ahead Joe. (Yes you are Neal. Just a bit. :-)
JOSEPH T. POPE: do you have any experience with the Sony drive, we could
never get one to work
*Tim Oren: Which Sony drive? I have used both the CDU-1 and the CDU-100.
Jeremy(JNL Tek ): Damn call waiting!
JOSEPH T. POPE: cdcdu-1
*Tim Oren: (OK, Jeremy. You're o deck.) Joe, are you using the CDU-1 with a
plastic disk, or with a glass master? ga
JOSEPH T. POPE: with the plastic demo disk that comes with it
*Tim Oren: Our experience at KnowledgeSet was that the CDU-1 had a lot of
trouble with plastic. It appeared to be a problem with the optics. It
worked fine with a glass disc. The things are not exactly mechanically
robust, shall we say. We destroyed two of them by taking them on airlines
and to trade shows. The new model (CDU-100 is much more reliable and faster
to boot). ga Jeremy
JOSEPH T. POPE: thanks, we had similar problems with sony. none so far
with Hitatchi, guess we will stick with it
Jeremy(JNL Tek ): Tim,I used to be president of the new york a.c.e. users
group, Have you ever considered writing an article or two for a UG newsletter
on cd roms?
*Tim Oren: I have written one article for IEEE on the subject, and I am
working on another on
August 23, 1986 CD-ROM CO Page -7-
Jeremy(JNL Tek ): most groups would kill for an article by you
*Tim Oren: CD hypertext applications which will probably go into an ACM
publication. but right now my writing schedule is completely overrun with
that paper, the columns, and programming. So I guess the answer is not at
this time. BTW, for those who want an intro to CD, the Microsoft book is
overpriced and full of self-serving tripe here and there, but there are some
gems. You might borrow a copy and read Laub's article on CD hardware, and
Fox's article on information retrieval at least. (My article appeared in the
IEEE Spectrum for April, with a companion piece on CD hardware.) If you go
read those, YOU will know as much as some of the self proclaimed experts!
(GA Jeremy. Your last MS got trashed by the system, I think)Jeremy(JNL Tek
): I thought it was your ms got trashed nah,that was it..ga. (Or WAS trash,
hehe!: Anyone else?
Dave Akers: ?
Dave Akers: What is 'the record group'?
*Tim Oren: The Record Group is a Los Angeles company run by Stan Cornyn. He
spun off from Warner's entertainment group
Jeremy(JNL Tek ): ?
*Tim Oren: (quick trivia: what other company did that?) and still has good
relations. His specialty is audio products,and he is in league with the
Philips Interactive Media people to work on CD-I projects. Supposedly has
some titles in production, though he can't be too far along, considering the
CD-I spec isn't finished! ga Jeremy
Jeremy(JNL Tek ): Tim,are you ever in NY to maybe speak to our users
group?
*Tim Oren: I seem to hit NY about once every other year, at least on trips
where I am not just doing business. So odds, aren't good, but mail me your
PPN and address via Eplex and I will keep it on file. WHo's next?
Jeremy(JNL Tek ): ?
*Tim Oren: Ga Jeremy again
Jeremy(JNL Tek ): Tim,it was nice meeting you,I haveto run..hope to type
at u again..
August 23, 1986 CD-ROM CO Page -8-
*Tim Oren: OK. Ditto. Ciao!
Jeremy(JNL Tek ): have some programing to do..
Jeremy(JNL Tek ): bye!
*Tim Oren: Anyone else, or shall we get on with our weekends? ga anyone
JOSEPH T. POPE: thanks and have a good weekend
*Tim Oren: Going once
Dave Akers: bye
*Tim Oren: It's rather munged up of course. If you'd like I'll upload it raw
the SIG right now. Name the DL (Sheesh, my typing is deteriorating: ga
SYSOP*Dave Groves: Use 9, and I will grab it and edit shortly.
*Tim Oren: Anyone for a last question before I turn into a pumpkin? ga anyone
Going twice Gone! Please leave any followup questions on the open SIG,
unless they are private business. Let everyone see them. It's been a
pleasure, gentlemen. Now I will drift down to SIG and upload the capture.
See you on the bitstream.. (Off)
