Now that CDTV is available, a question/proposal: How about making an MS-DOS emulator that is specialized in reading and running MS-DOS CD-ROMs? There are many such discs out already, but most of them come with proprietary software on them for querying, and this software is mostly written for MS-DOS. So: IBeM author, are you hearing? Doesn't this sound interesting? And for the same matter: How about an AMAX-CDTV? Then you could run all those CD-ROMs for Macs. Well I know, we only have a 7 MHz 68000 there, but for those query programs, it perhaps will do. Oh, I forgot, when CD-ROMs carry graphics, this is normally at least EGA, so this could turn out as the hard part. -- Best regards, Dr. Peter Kittel // E-Mail to \\ Only my personal opinions...

That would be unfeasible, as you would have to add far too much to the CDTV in order to make it work. You would have to add a monitor, keyboard, floppy drive, and more memory. It would be much better to simply modify the Janus software so as to allow Amiga CD-ROM drives to run IBM CD-ROM software when used in conjunction with a BridgeCard. Allowing an Amiga CD-ROM drive to run MAC CD-ROM software when used with A-MAX would be up to ReadySoft, the developers of A-MAX. > >Well I know, we only have a 7 MHz 68000 there, but for those query >programs, it perhaps will do.

There is so much potential with this software that >has to date been totally ignored by Commodore. (Can I do it? Huh? Please?) OK, I'm going to say this slowly. There is no software problem. It's a hardware problem. MS-DOS provides such pitiful support of the serial port that nobody uses it. Every terminal program I know of goes directly to the hardware. A bridge board that could handle this would have to emulate chip addresses and bit patterns before Janus could even begin to work with it. This means hardware, unless you like working at 300 bps. If you don't know how serial port access works on IBM clones, you probably don't realize that video access works exactly the same way. The bridge board manages to emulate hardware for two different video interfaces (MDA and CGA), and Janus manages to talk to it well enough that the 99% of IBM programs that hit the video chips directly (even games!) can work. Hell, there probably isn't enough memory bandwidth left to emulate the serial ports too. My guess is that those good folks at Commodore, whose commitment (and by implication competence) you seem so willing to question, had spent so much time and effort making bridgeboard/Janus (hardware AND software) work that even if they weren't taking a well-deserved rest they still have to go and devote a bit of time to other things - like the A3000, or the Display Enhancer, or the multi-serial board, or the Ethernet board, or Unix. If you're so concerned about serial ports on the bridge board (and not just looking for another excuse to flame Commodore as I suspect) get yourself a multi-I/O board and drop it into a bridge board slot. One parallel and two serial ports, cheap like borscht. In case you're wondering, here are a few credentials. This is my hardware set-up: A2500/20 40MB hard drive 880K 3 1/2-inch floppy drive flickerFixer with multi-scanning monitor Roland KX-P1124 printer A2286 bridge board 720K 3 1/2-inch floppy drive 1.2-megabyte 5 1/4-inch floppy drive 30MB hard card (in a bridge board slot) Multi-I/O board (in a bridge board slot) I didn't get this system to whine about it. I got it to develop and support a commercial MS-DOS-based telephone management system. Among other things, the proceeds from the 600 systems we have in the field enabled me to buy my wife a 2500/30 with HP LaserJet IIP for desktop publishing (heck, we gotta get a prettier manual out somehow :-), not to mention the down payment on our current house. The bridge board works. It works well. I have a complete AT tucked inside my Amiga, and it beats the hell out of cluttering my desk with a brain-dead box. When I want to work on some programs, I awrite them over the the Amiga side and use CygnusEd and other sophisticated tools (concurrently!) which give me a big performance advantage over anything MS-DOS could offer. I can compile a program on the bridge board while working on the next one on the Amiga side. It's a great environment for serious development work. If I have anything to whine about, it's MS-DOS itself (I can tell you plenty of horror stories about that brain-dead operating system) and not the great job Commodore did getting it to run in an Amiga at all. If you really want an IBM PC, go get yourself a cheap clone. Then maybe you can snivel at the people on comp.sys.ibm.pc, and leave us alone. Charlie_Gibbs@mindlink.bc.ca MS-DOS: I hate it, but I use it - twice a day.

Commodore has not satisfactorily upgraded the Janus software. In addition to the use of an Amiga CD-ROM drive to run IBM CD-ROM software, a feature that Commodore should have included a long time ago is the ability to use any serial port or modems on the IBM side with Amiga software. Internal modems and multi-serial port cards for IBM are less than 1/5 the cost of similar cards for Amiga, and it would be nice to be able to use these cards with Amiga software. In short, I call into serious question Commodore's commitment to the Janus software.

Allowing an Amiga CD-ROM drive to run MAC CD-ROM > > Get serious. JANUS won't even use the serial port yet! janus doesn't use the amiga's serial port for two reasons: 1) the original designers did a silly thing - they decided that software and hardware could share the same interrupt vector for radically different things. the interrupt they picked was IRQ 3 (software INT 0BH). that's the COM2: interrupt. imagine the fun when Telix or your favorite PC terminal program grabs the IRQ 3 vector to provide interrupt driven serial i/o. no more janus software (which depends on INT 0BH). 2) the original designers didn't think very hard when they designed the COM2: emulation hardware in the custom chips (they didn't think very hard when designing the LPT1: emulation either, or the CGA emulation...). ie, the COM2: emulation hardware does such a poor job that it wasn't worth enabling. i don't know how pc's deal with CD ROM drives (ie, do they have real MS-DOS filesystems on them? is there a special filesystem? do they have to fondle the hardware themselves?). if they did a reasonable job, it should be possible to intercept the requests from the application at a suitably high level and direct them to the amiga (much like what JDISK.SYS does). the level at which you tap into the connection between the application and the device should be low enough that you're not duplicating alot of ms-dos functionality on the amiga side, but high enough that you're not at the "emulate the hardware registers" level. >***************************************************************************** >* Stuart Millington * "A Mind Is A Terrible Thing, Remember * >* UUCP:...!mcsun!ukc!warwick!phupp * That." - David Bryan, Bon Jovi * >* JANET:phupp@uk.ac.warwick.cu ***************************************** >* ? :phupp%warwick.ac.uk@nsfnet-relay.ac.uk * >***************************************************************************** --Scotty -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Scott Drysdale Software Engineer Commodore Amiga Inc.

"intelligent" in this context means it's got it's own CPU to offload interrupt overhead from the host computer. in both of these examples, don't forget to add in the cost of the bridgeboard. $400 for the 2088 (XT) or $700 for the 2286 (AT). somehow i think using real amiga cards comes up alot cheaper. > In short, I call into serious question Commodore's commitment to the >Janus software. There is so much potential with this software that >has to date been totally ignored by Commodore. ^^^^^^^^^^^^^^^ um, i don't think so. there is indeed alot of potential. but how much of what is possible (as far as the amiga using pc peripherals and vice versa) can't be done better by normal amiga devices (or vice versa)? yes, there are some people doing some rather obscure things with bridgeboards because some kind of arcane card is available for the pc, but they'd rather program and amiga. as for general appeal to users, it might help out the hobbyist who has access to a bunch of virtually free pc hardware and *already* has a bridgeboard. but i don't think there are enough of those types of users buying bridgeboards to actually make a bridgeboard that much more attractive. the bridgeboard has two purposes in life: 1) to let people who have an amiga but need to run pc stuff occasionally do so easily and conveniently (easy data sharing, enough hardware sharing to get by). 2) to help business purchasers who otherwise would not be able to buy an amiga to do so. you: "boss, i'd like an amiga instead of one of those compaq's when we order those pc's." boss: "is it ibm compatible?" you: (slyly) "well, yes!" boss: "ok, if it's not too expensive." >>* Stuart Millington * "A Mind Is A Terrible Thing, Remember * > / Marc Barrett -MB- | BITNET: XGR39@ISUVAX.BITNET / --Scotty -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Scott Drysdale Software Engineer Commodore Amiga Inc.

JANUS won't even use the serial port yet! You can't use the Amiga's serial port via Janus. That's an MS-DOS problem, not an Amiga problem. MS-DOS basically assumes the exact bit patterns that your serial chip will have in its registers. It's impossible to emulate a hardware device at that detail and get any speed out of it. >In addition to the use of an Amiga CD-ROM drive to run IBM CD-ROM software, >a feature that Commodore should have included a long time ago is the ability >to use any serial port or modems on the IBM side with Amiga software. That, on the other hand, could be done, since the Amiga device driver model would allow the IBM-side processor to handle serial interrupts and buffering, and it of course makes no assumptions about what the underlying hardware looks like. Far as I can tell, there's no reason Commodore has to write such a program for you; if you're a programmer, the Janus docs are available. Or, if you want to brute force it, you could take over the BridgeCard with some kind of custom server program of your own (MS-DOS isn't going to be much use with your serial server running, unless you figure out how to do it as some kind of device driver or TSR, like the janus hard disk -- I'm not at all up on what's actually possible under MS-DOS). >Internal modems and multi-serial port cards for IBM are less than 1/5 the >cost of similar cards for Amiga, Dang, if you can get a 6-8 port serial card with CPU for the ISA bus for under $50, I bet you could actually make some real money on the Janus serial server for it. Even without CPU (hell, the 8088 on the original Bridge Card bangs bytes around better than 1/4 the speed of the 4502 on the A2232; you might get it servicing four ports on its own real nicely). > In short, I call into serious question Commodore's commitment to the >Janus software.

"Son, that's what we call an opportunity." - Foghorn Leghorn Commodore cannot possibly write Janus cross drivers for every ISA bus card under the sun. If you see an opening, go for it!

In the last week, on the NET someone from commodore - can't remember who, stated that the only way commodore would tell end users how to use the JANUS.library, i.e. provide documentation for software the customer has already bought, was is the end user became a JANUS developer!!!!!!!! How much does that cost:-) How are end users expected to write stuff for JANUS when commodore won't release the docs publicly? I would BUY a manual, "JANUS Programmers Reference Guide."? Even if I could afford to become one of these elite JANUS developers I doubt I would qualify - given the qualifications required to become a registered developer for other areas of the amiga system. In short commodore is not allowing the end users, their customers, to write the drivers that you suggest they could/should. If commodore will not allow us to write the they are by defult taking on the responsibility themselves - OR deciding to ignore bridgeboard users. Personaly I only rarely use the bridgeboard, but it is a real pain having to source a PC I/O card so I can use a serial port, when there is already a perfectly good one on the amiga - even 2400/4800 baud would be useful. BTW - The ATonce does allow you to use the amiga serial port. So it can't be that hard to implement. ***************************************************************************** * Stuart Millington * "A Mind Is A Terrible Thing, Remember * * UUCP:...!mcsun!ukc!warwick!phupp * That." - David Bryan, Bon Jovi * * JANET:phupp@uk.ac.warwick.cu ***************************************** * ? :phupp%warwick.ac.uk@nsfnet-relay.ac.uk * *****************************************************************************

How about the long-sought dumb bridge board? Just enough hardware to let Amiga software address the PC bus. Then I could stick a couple of 2-port dumb cards with good uarts in for $60 (total) or an AST dumb card for $100 and get 4 ports. The dumb bridge card couldn't cost more than $100, and should be less than that. I could probably cannibalize the famous FAS driver for much of the hardware control. If the Bridge card is just for PR, as you imply, why doesn't my 3000 have Amiga slots inline with *all* the PC slots? -- Peter da Silva. `-_-' <peter@sugar.hackercorp.com>.

MS-KERMIT (the *best* VT100 emulator for the PC) will use the BIOS calls. One is good enough for me! In fact, in testing it we were able to get a quality 300bps out of it. Of course, we did try it on an 286 and we were able to get about 450bps and have it still be reliable. Of course, our goal of 9600bps was met, but the BIOS routines missed all but 1 in 12 bytes, but what else do you want? PERFECTION OR SOMETHING??? Tom P.S. Those are real test results.

A real pain! NOT! A serial card in an 8bit config with a printer port and game port can be had for $19. A used one may be $10. Besides what do you need one for? You can use the printer port with the Bridgecard and downloads can be done on the Amiga side and transfered over. (Using some nice software written for Janus by CBM :-)) As for Prodigy.... HA! >BTW - The ATonce does allow you to use the amiga serial port. So it can't >be that hard to implement. I think it may be bigger than you believe. If not, it would have shipped with the first XT bridgecard.. Besides, I would imagine the dual-port ram transfers wouldn't be fast enough to allow any software to redirect all access to an IBM com port to the Amiga serial.device and also maintain any sort of acceptable transfer rate. ///\ _ '_/ \X//_/(/|//(/ -- "All of us get lost in the darkness, dreamers learn to steer by the stars.
