If each disk is EXPLICITLY formatted from the finder, you are okay, but if you (like myself) use the 512K Disk Copy utility to make multiple copies, the disks will NOT work if you let the utility copy them. I think this might be because the default initialization routines on the 800K drives are for double sided disks. This is just a guess however. The lesson is: format the disks first, then do a 512K disk copy. -Tom Dowdy "If it jams, force it, if it breaks, it needed fixing anyway" Long live Megamax C! ------------------------------ Date: Mon, 9 Jun 86 23:27:09 PDT From: kegel@Juliet.Caltech.Edu (Dan R. Kegel) Subject: Sources for ls or whereis A friend is trying to write the Mac equivalent of the MS-DOS program 'whereis', which searches the HFS for filenames matching a given pattern. Do sources for such things exist (in C, Megamax, preferably)? Actually, we'd settle for an explanation of how to get a list of files in a certain directory from a C program, without running ls.

I'm trying to get the correct capitalization of the name, i.e. "foobar" ==> "FooBar" if that's what the user called it when he created it. _GetFileInfo seems to leave the name as you pass it except in the indexed case. As far as I can tell however, there is no way to get the index of a file from its name or its file number (short of walking thru the whole directory, which is too costly), so that's not helpful. Any other suggestions? ------------------------------ Date: Sun, 15 Jun 86 19:37:13 EDT From: Howard Walter <howard@BRL.ARPA> Subject: Imagewrite II mechanical adjustment I have an Imagewriter II connected to a MAC+.

Yes, it is under warranty but I would prefer to do the adjustments myself! Thanks Howard ------------------------------ Date: Tue, 10 Jun 86 10:10:09 cdt From: wmartin@ngp.UTEXAS.EDU (Wiley Sanders) Subject: Bug in Edit, version of 28 Oct 84 Reply-to: wmartin@ut-ngp.UUCP () There is a nasty bug in the Consulair Editor, "Edit" that came with my version 2.0a of Absoft (now Microsoft) Fortran. This is the "ver- sion of 28-Oct-84" of Edit as noted in the "About Edit" menu item. If you hack on your file for a while, then select "Quit", and click the "yes" button when edit asks you if you want to save your changes, your changes will not be saved and you can lose the work you have done. This will happen if you have changed the display font or fontsize of the file; Edit saves the change to the font, but not any changes you have made to the text of the file. If you have made changes to the file, and have not changed the font, the quit seems to work properly, i.e. the file is saved first. The fix seems to be to explicitly select "Save" before quitting Edit. I presume there is a newer version of Edit that has corrected this problem. I submit this to warn those who are using the older version. ------------------------------ Date: Thu, 12 Jun 86 22:00 pst From: "pugh jon%e.mfenet"@LLL-MFE.ARPA Subject: Disk Librarian I downloaded Disk Librarian and it still crashes with surprising regularity.

I have been running Klondike and Capt. Magneto under the Switcher and getting different responses than if I run it by it's lonesome. Notably, Klondike does not play the intro "Sting" music regularly. Sometimes it plays and sometimes it doesn't. I can't see a pattern. Capt. Magneto doesn't talk, although if I quit the other applications and fire it up by itself, it works fine. Is Switcher to blame? I am running Switcher 4.9 on a Mac+ with Finder 5.2 and Versaterm in rotation with each of these games. Maybe I'll check out Concertware+...

Wald <6090617%PUCC.BITNET@WISCVM.WISC.EDU> I'm having a strange problem with Appletalk & Lightspeed C. I am just doing some simple functions in Appletalk before diving into writing a real program with it. I am opening an ATP socket and giving it a name (NBP). These seem to go alright. After doing this I immediately remove the name from NBP, which also seems to succeed. But when I try to remove the socket with ATPCloseSocket, I get an error -1099 (badATPSkt). This error also prevents me from opening any more sockets if I rerun the program! (Error -91) I think I am giving it the correct numbers: ATPOpenSocket(0L,&socketnum); (Byte socketnum) (socketnum=0 initially) and immediately ATPCloseSocket(socketnum); which returns -1099. The problem occurs even when I don't use NBP. I can create a socket again only after using the control panel to turn Appletalk off and then on. But the same problem reoccurs. Also, Setting socketnum to 0 should give me a dynamically assigned socket, but it assigns socket 0, is this a legal socket? Any suggestions? -----By the way, reguarding the posting about the SFGetFIle problem, the problem is that you must give SFGetFile a POINTER to the typelist, so you should have SFGetFIle(apoint,NIL,NIL,2,&typelist,NIL,&reply); ------------------- Nexus -------------------- -Rob Wald (PUCC User Services) BITNET: 6090617@PUCC UUCP: ...ALLEGRA!PSUVAX1!PUCC.BITNET!6090617 "Behold, I teach you the Superman!

In my case, ATPOpenSocket returns -1098 (tooManySkts), and leaves the socket number 0 (I don't think this is a legal number for a dynamic socket). I suspect the problem is in the Appletalk routines supplied on the Lightspeed disks. I notice that they are over a year old, and suspect that they may not be compatible with System 3.1.1. Several months ago I wrote some programs under Megamax C using the Appletalk routines. I based my interface routines on the articles in August and September (maybe Sept/Oct) 1985 MacTutor. These routines make direct PBControl() calls to the Appletalk drivers, and they do work correctly. The open socket routine returns noErr, and the socket number is dynamically assigned, nonzero, and different each time that I run the program. I recompiled the Megamax programs under Lightspeed C, using the driver interface routines which make the PBControl() calls, and they still work correctly under System 3.1.1, WITHOUT loading the Appletalk resources supplied by Lightspeed. If I do load those resources, the programs stop working. If I then remove those resources (by disconnecting and then reconnecting Appletalk through the control panel), the programs start working again. It would appear that the Appletalk resources supplied by Lightspeed are not really necessary at all, at least under the new ROMs and System 3.1.1, but so far I haven't been able to get the Lightspeed ATPOpenSocket() call to recognize anything but the resources on the Lightspeed disks. Anyone have any better success? ------------------------------ Date: Thu, 12 Jun 86 15:09 PDT From: PUGH%CCV.MFENET@LLL-MFE.ARPA Subject: Copy Protection... There is an excellent article on copy protection, the whys and hows, in the IEEE Spectrum magazine for June 1986. I recommend it if you are interested in the details about that sort of thing. It's not a very technical article, but it presents overviews of the various popular methods and a discussion of the legal aspects.

Edwards <DLE@SRI-AI.ARPA> Subject: Paradise Drive Bug [Uploaded to INFO-MAC for Reid Larson, all replies will be forwarded to him.] -dle This file describes a serious deficiency in the MAC-10 and MAC-20 hard disks from Paradise Systems, Inc. It can occur whenever there is simultaneous I/O to or from the disk, and from the modem port. The problem is subtle enough that others who have run into the problem may have attributed the symptoms to telephone line noise. A little background: The paradise MAC-10 & MAC-20 are connected to the Macintosh via the printer (or modem) port. During I/O, it has to disable interrupts, just like the floppy I/O drivers. This is why mouse movements get flaky during any disk I/O. Losing mouse interrupts is just a minor inconvenience. Losing modem port interrupts is more serious. The Apple floppy I/O drivers check for incoming modem characters and save them until interrupts are re-enabled. (See hardbound Inside Macintosh, page II-246 on the bottom of the page.) There's no problem with what I've described so far - these are just quirks of the Macintosh. The essence of the problem with the Paradise disks is that they ignore interrupts on the modem port during disk I/O. What this means to the user is that incoming characters can be lost during I/O to the paradise disk. The problem can be easily reproduced in Red Ryder. Just turn on "ASCII file receive", and then type a command on the host system that generates a lot of output. If the file receive is directed at a floppy disk, everything works fine. If directed at a Paradise volume, characters will be lost. The problem can also be reproduced in a similar manner with MacTerminal 2.0 by specifying "Log lines off top". The problem will likely not occur during XMODEM receives (at least not in Red Ryder) because the host system is not sending any characters when the Mac is writting to disk. An optimally written (does such a thing exist?) XMODEM would have problems, because it would overlap disk I/O with incoming packets to achieve a degree of concurrency. The problem can be avoided by recording to a floppy disk, rather than to the Paradise disk. I advised Paradise of this problem on June 9 and June 10, but was unable to get the problems resolved. They never returned a single call. After waiting on hold, I confirmed with Paradise that I have their most recent software version, 2.5. (Note that the "Start Paradise" program is version 2.0. This is where the bug lives.) I finally got through to a support person who suggested that I use SmartCom, since they haven't had any problems with it. If you have encountered this problem, please call Paradise at (415) 588-6000, or write to them at: Paradise Systems, Inc. 217 East Grand Avenue So. San Francisco, CA 94080 Perhaps if they get enough calls, this will be fixed. If I get a fixed version, I will upload an update to this file. Reid A. Larson ------------------------------ Date: Thu, 12 Jun 86 12:32:32 EST From: Richard Crane <CRANER%YALEVMX.BITNET@WISCVM.WISC.EDU> Subject: Tincan info In response to a recent query, here is some information on Tincan. ========== Tincan is a terminal emulator designed to operate in conjunction with the Yale ASCII Commmunications System, a hardware/software package that allows ASCII terminals and micros to access IBM mainframes as 3270 style fullscreen terminals. Yale ASCII is available as 1) software to run on an IBM Series/1 2) the IBM 4994, a repackaged S/1 with the software, or 3) the IBM 7171, a IBM PC-based version If you have any of these attached to your mainframe, then in conjunction with Tincan on the Mac, you get full 3270 support with some enhancements. By adding PCTRANS, a host command available for a nominal charge from the Yale Computer Center, you get error-free file transfer of text and binary (Mac application) files to/from the host. Tincan also supports DM1521 and a limited VT100 emulation to VMS and Unix 4.2, and PCTRANS is available for these hosts as well. There is an autologon feature, session capture, alternate printer support, onscreen buttons for common commands, and a keyboard map help facility similar to the Keycaps DA; a TTY option is also available. The program can be modified using custom RESEDIT templates; almost every default can be changed, the keyboard remapped, logon sequences defined, and up to four user selectable different "services" or host configurations set up. I'd be glad to answer any further questions: you may send me mail directly to my BITNET address: CRANER@YALEVMX.

I agree that the reader seemed to work fine but the licensing materials that came with the strip producing software essentially said that Cauzin has to be paid royalities on anything you distribute that was printed by their program. We had hoped to use this medium as a way to cheaply distribute code, but I can't see any great advantage in paying royalities to the current scheme of posting to the networks or exchanging disks. We didn't think they would do this -- after all, the reader has value only if there is a large software base to read. But I guess they think they can get as much as possible this way. Anyone still using First Byte's Smoothtalker in their application? ------------------------------ Date: Mon, 09 Jun 86 11:27 PDT From: Dave Platt <Dave-Platt%LADC@HI-MULTICS.ARPA> Subject: Printing Softstrips... I believe that Cauzin is keeping the actual strip-format algorithms proprietary. Originally (as of the Feb. '86 MacExpo I attended) they were saying that software developers would have to go to Cauzin to publish their software in strip format. However, as of a month or so ago, Cauzin started advertising a program that will permit anyone (who owns it) to generate low-density Softstrips on an Imagewriter I or II. I don't recall for certain, but I think it might also be able to generate medium-density strips on a Laserwriter. According to the Cauzin rep I spoke with, the high-density strips require even more resolution than the Laserwriter provides, and must be printed larger-than-life and then photographically reduced to their final size. The strip-printing application can be mail-ordered from Cauzin; it is apparently shipped in Softstrip format (what else?) and "is not photo-copy protected." The price seemed pretty reasonable (I think it was $19 but it may have been more). ------------------------------ Date: Fri, 6 Jun 86 16:45 PDT From: PUGH%CCV.MFENET@LLL-MFE.ARPA Subject: MacSpin I would like to thank the people at D**2 Software for quoting my network review of their product MacSpin in their promotional literature. If anyone affiliated with them is listening, please pass along my comment that they need to modify the list of computers that are crunching data for MacSpin to work with. I have personally crunched data on our Crays and analyzed it with MacSpin and Excel. (Is this what we call reverse engineering? :-) So my comment boils down to a list of places to get data: IBM 30XX Series Digital VAX Series Prime Minicomputers Sun and Apollo Workstations Other Microcomputers (IBM Compatible) Cray Supercomputers!!!!! The advantage a Mac has over a Cray is two-fold. It's yours alone and it is so much friendlier. I work as a consultant, helping people use our Crays and I can tell you that if the Crays used as pleasant an OS as the Mac has, I would be out of a job. Of course, now all we need is a Mac with a clock speed of 250 MegaHertz and the ability to pipeline floating point operations...
