I'm looking for some documentation, or even just the pinouts, on the
Mega ST's internal connectors. These are the CPU buss and the internal
DMA port. If you could point me to some documentation, or just give me
the pinouts, I'd be most grateful! Thanks.

(Send in your $300) That's not quite true. For $120 U.S. (and change) you can purchase just the developer's documentation, which contains the pinouts you seek. Of course, for this amount of money, you don't get a compiler, a newsletter, or phone support (I know, I have the docs). Call Atari Corp. at (415) 745-2000, and ask for Cindy Claveran. Tell her you want the documentation only, and she will give you the details.

Yes, that's true... but if all you need is that one connector pinout diagram, $120 is an awfully steep price to have to pay for just one page... Especially in light of the equivalent information being published by Apple and Commodore/Amiga in $19.95-$29.95 books, available at just about any B.Dalton Bookseller. I imagine too, the page with that Mega expansion buss pinout is stamped "Proprietary Information", so that it can't be uploaded on UseNet (or anywhere else)... BobR

The Atari Mega st internal connector.
The signals provided on the 64 pin connector are essentially the
pins of the 68000 processor. The diagram below shows a top view
of the connector with its associated pin numbers and signal
names. Active low signal are followed by: (L)

I suppose that this means that they feel support is only worth $25... (from the way developers talk about the quality of the documentation on the net, you'd figure that it should be $25 for docs and $125 for support). ron

Frankly, I don't know what to think about all this "proprietary information" stuff about the Mega bus. Here in Germany, a magazine has published the pinouts of the bus (I think it was c't), and another one even published the schematics for adding a Mega bus to any other model. Would I commit copyright infringment if I posted the pinouts on the net? I payed for the info anyway.. although not to Atari -- Federico Heinz "In Dubio Pro Libido" From USA: ...!pyramid!\ | Beusselstr. 21 From elsewhere: ...!mcvax!unido!tub!actisb!federico | 1000 Berlin 21 Tel: (030) 396 77 92 | F.R.

I called Cindy and left a message on her answering machine; she does not seem to answer the phone herself at all. I said I was interested in registering, but I already have the MWC compiler (in fact I am a beta-tester for them). I got back the standard package (with my name misspelled :-) requesting $300 and my first-born child. Ho hum. Repeated calls back to Cindy to straighten out what I really wanted result in the answering machine (and me hanging up). I also don't understand why the $120 package doesn't include the newsletter, all they are doing is subtracting the retail price of MWC from the $300.

Could you give us more information on the magazine which published the information for adding a Mega buss to other STs, the name and issue date of the magazine, and an address for the publisher, if you have it...? Perhaps we could arrange for reprint rights in the U.S. I'm sure a LOT of people would be interested..! BobR

Sorry for the late answer, I've been out of town for a while. In the meantime, somebody posted the bus pinouts, so that problem has been solved (at least apparently). On the Mega bus expansion for smaller models, I'll check the magazine at home and post the info. -- Federico Heinz "In Dubio Pro Libido" From USA: ...!pyramid!\ | Beusselstr. 21 From elsewhere: ...!mcvax!unido!tub!actisb!federico | 1000 Berlin 21 Tel: (030) 396 77 92 | F.R.

I would definitely not assume that if something is published by a German computer magazine, it is not proprietary or not copyrighted by a third party. German magazines have a disregard for copyright laws that is second to none in the whole world (a example: the otherwise excellent "c't" actually published a complete disassembly of AHDI.PRG and the author of the article put his own copyright notice on it!!! (not to mention the various patched TOS ROM's that you can buy)). -- ---------------------------------------------------------------------------- UUCP: ...mcvax!cernvax!forty2!poole Simon Poole BITNET: K538915@CZHRZU1A ----------------------------------------------------------------------------
