This is in response to a message by <bouldin@ceee-sed.ARPA> entitled "Where is the 68020 Macintosh" in which a friend of his made some comments that I felt deserved replies. The man said some things about "Motorola people" and "Intel people" that I found not only ludicrous, but downright innaccurate.

First of all, 68020 machines have been around since shortly after the chip was announced. Most of them instantly became 68020/881 machines when the 881 was released, since many of the designers left a spot to plug one in. I think you've focused too hard on the business and/or home markets. Flexible Computers in Dallas has had 020 and National 32032 modules for their parallel machines for almost a year and a half. They chose not to design 386 boards, because "Intel doesn't have both oars in the water." As for pricing, have you ever bought a mainframe computer? I'd be willing to bet they're a little bit out of your price range. I've not seen a mainframe computer yet that cost less that $1 Million. Levco never claimed mainframe performance. They DO claim super mini-computer performance, and they come through with flying colors. The Prodigy 4 runs as fast as a VAX 11/780. A VAX 11/750 runs at 60% of 780 levels. The VAX 11/750 that this message is beiOAng sent from was bought in 1984. It had 2 Mb RAM, 125Mb on-line storage, and FP co-processor. It requires a rasied floor in an enviromentally controlled room, with special power requirements and a full-time system manager. It cost $125,000 (at educational discount) and has a $12,000/year maintenance contract (this is part of a $1 Million/year campus-wide contract). The average buyer can put together a Mac+ with a Prodigy 4, OverDrive, and big screen for about $13,000. Being a Levco dealer and a Certified Developer, I can put the same system together for about $9,000. I'd say paying $9,000 to do what I could do on a $125,000 machine is pretty good. Go ask Sun or Apollo how much they want for a similar system. > Despite my dislike of intel, at least they have always made "people's > computers" that , while being absolute kludges, were at least priced at an > affordable level. Intel doesn't make computers. But I agree that most machines that have Intel processors are kludges. > Also, they didn't snub the engineering users and included > a FP processor from the start. Wrong. The 8087 wasn't available when the 8086 and 8088 came out. The 80187 wasn't available when the 80186 hit the scene, either. > Contrast Motorola. Even the mac was way overpriced at the outset; > would you have bought one at the list price? And NO FP coprocessor > (Motorola's laziness). What does Motorola have to do with the Macintosh being overpriced? I think you ought to take that one up OBwith Apple. The 68881 is a phenomenal chip, and will be around for a long time. The fact that it took a while to get here only shows that Motorola was unwilling to rush the design, leave features out, and release an inferior product. To me, that shows dedication, not "laziness." CONTRAST INTEL. Pay attention, too, that Motorola's 68xxx processors support the idea of coprocessors so well that you can actually put an 8087 math coprocessor on a 68000. (It's not quite just "plug and go", but it is relatively easy. Try putting a 68881 on an 80386 and see what kind of headaches you get.) Of course, who really wants to when you can have the far-superior 68881? And before you do much more name calling, you might want to meet some of the people involved in designing Motorola's processors. I did, and the two I met are very nice HUMAN BEINGS, who care very much about doing the best job they can. > Despite the fact that the 020 was out much earlier than the 386, we finally > have the compaq out at a reasonable price (presumably available NOW).

For a reasonable price you can have a machine that beats the stuffing out of IBM machines, and the rest of the clones and knock-offs. But, it won't out-perform the Prodigy by a long shot. Nobody ever claimed the Prodigy to be useful to business types, or home use. It is aimed at scientific users (and those "snubbed" engineers) who don't want to pay an arm and a leg for computing power. > What is apple doing? Absolutely NOTHING! They have to wait for their ridiculou s, > magical stockholders meeting to announce anything. Even the inexpensive Atari > and Amiga do not invalidate what I am saying, since the absence of a standard > 68xxx operating system (Apple's greed?) makes these computers lame ducks. What do you mean, NOTHING?!?! The new Compaq requires no more sophisticated hardware than already exists in countless IBM's and clones. And, it uses an operating system that had its roots in CP/M 1.0. Apple's new machines, however, are keeping pace with the latest in hardware and software technology. Witness the desktop metaphor on Macintosh, and the custom chips at the heart of the Apple //gs. Personally, I want Apple to continue moving the industry forward rather than hold it back for the sake of "compatibility." As for waiting for a stockholder's meeting, I suppose a Compaq engineer just decided one day that the machine was ready and started sending out flyers. A standard 68xxx operating system? Try CP/M 68k. You sound like you'd probably like it. Using a stupid system just because it is a standard is just that: stupid (and what does Apple's greed have to do with THAT?). Hey, I've got an idea! How about asking Apple to give away the operating system and toolbox to any good joe company that makes 68000 machines. I'm sure that Commodore and Atari wouldn't use it to help Apple go broke and REALLY start doing nothing. After all, it's just one big happy family, right? > I fear that very soon we will see some very reasonably priced 386 machines > which lack that which we hated on the pc or "at": segmentation and lo res > graphics.

Maybe someday we WILL see a product based on an Intel chip that lacks the features we hate in a PC or AT. Maybe Khaddafi will be invited to lunch at the White House. I KNOW we'll see more hardware from quite a few manufacturers in the future. More competition can only improve the situation for the end user. Whether these machines are 386 based or 020 based or "whatever" based, its what the user sees on the outside that really matters. IBM is committed to phasing out the entire PC line within about three years, to be replaced by "workstation" type equipment. Apple's success in this area had a large impact on IBM's decision. Apple has been looking at the 386 in order to offer MS-DOS compatibility to its new machine. What will you think when this machine has a 68020, 68881, AND an 80386? And as for Levco's people being "smug elitists", have you ever met them? I have. They've got a lot of smarts, both in engineering and in marketing. Their machine costs as much as it does for several reasons. First, memory prices (thanks to Uncle Ronnie) have gone back up. Second, the high speed 020 and 881 aren't cheap either. Third, I'm sure they are trying like mad to make back development costs before Apple releases ITS 020 machine and takes away Levco's biggest edge: uniqueness.

Each requires a different implementation. Informational messages you do not really care if they are read, (possibly debug messages), just like a FYI note in your mail box. Warning messages may cause the user to change their mind about continuing like a "I can't find the file". Error messages indicate that right after you read this message the program is going down the tubes or back to the Finder. I think that many of the alert boxes that have a single button are actually informational messages, otherwise they would have 2 buttons (or more) and would behave more like warning messages. If the Dialog Mgr. had a way to save up the informational messages and then let the application display what had been accumulated so far in a single scrollable window, things would be a bit better. For informational messages, I build a window with the message in it and wait until either 3 seconds have passed or the mouse is clicked anywhere. For warning or error messages, I do the same but only wait for the mouse click. It seems excessive to make the user click only in a button if there is only one button. Bill Stackhouse bills.cca.cca.com ------------------------------ Date: Fri, 3 Oct 86 12:08:19 mdt From: jpm%a@LANL.ARPA (Pat McGee) Subject: Error box idea A couple of days ago, someone was complaining about dialog boxes for errors that stopped processing until the user clicked OK. This has bothered me for a while also, and the message asked for alternate methods for handling the problem. My idea follows. Implementation is left as an exercise for the reader. When an application (such as finder copying a folder) encounters an error (such as can't read or can't write), it opens a new window and writes the error message to it. Processing continues, with further error messages being written to the same window. When processing is complete (or blocked for user input), the application puts scroll bars & all that stuff on the window, along with the OK box (which wasn't there until just now). A cancel box is there all along, and the user may cancel the process at any time after the first error. This way, as many error messages as needed may be displayed, without the user being required to respond to each one individually, and without the process being blocked waiting for the user to respond. This system can be used anytime where an error is encountered that doesn't demand immediate action from the user before anything else can be done.

It has extensive documentation within the program and has two features for automating the startup process. First, and defualt, is that RamStart will transfer all files in the same folder as RamStart to the newly created Ram Disk. Second, with the help of a small script file, RamStart will copy specific files off of any volume to the Ram Disk and will even allow you to set startup to a program on the Ram Disk. In either case RamStart will transfer control to the Ram Disk and eject the startup disk if system files are on the Ram Disk.

This file is a hexified packit file containing the Pascal source, the executable, and a small addition for your help file. This is not a standalone program. It does require the MPW Shell to operate. The tool uses standard input and standard output. Since the Shell is so powerful with standard i/o, you can do things like dump things as you type them from the keyboard or select and ENTER them. It's a neat way to get the ASCII value of a character on the screen. You can also redirect your output. It has an option to output the dump in valid Rez format. If you expand, improve, or add features, send me code. I'm interested in what you want to see tools like this do. Greg Marriott A member of the MacHax(tm) Group Teenage mutant ninja turtles?

It has taken much longer than I planned, and in order to release it now I've postponed adding file transfer (which is the number one item on the list for the next version). Part of the reason for the delay was the total rewrite that UW underwent so that new features could be added more cleanly. UW is a multiple-window interface to UNIX (4.[23]BSD) for the Macintosh. A program on the Mac interacts with a server process on the host to provide up to seven independent terminal sessions. Each terminal session is conducted in its own window. The windows are independent, and can emulate an ADM-31, VT-52, a (subset of an) ANSI terminal, or Tektronix 4010. UW version 3.4 has a greater capacity for host-Mac interaction than the previous version (v2.10). If the host understands window resizing (4.3BSD and Sun UNIX do), then window size changes on the Mac can optionally be passed through to the host. The cursor-addressible terminal emulations are faster, although the Tektronix emulation is slower. UW v3.4 will not run on a 128K Macintosh. You should allow for at least 256K, although in extreme cases even that may not be enough. (I have not extensively tested it under Switcher.) It will run with the old ROMs or the new ROMs. I have no idea if it will work with third-party large screens (e.g. Radius). There is a new server for UW v3.4, although the old server will work with the new Macintosh program and the new server will work with the old Macintosh program. (To take advantage of most of the new features, both ends must be running the new software.) There are a few utility programs ("uwtool" and "uwterm" create windows in somewhat different ways, and "uwtitle" retitles existing windows). There is also a UW library which can be used to build other utilities. (The capabilities of this library are not fully utilized in this release; consequently, it hasn't been tested as thoroughly as I would have liked. Some of the future enhancements will draw more heavily upon the library.) The distribution is available now for anonymous FTP from S1-C.ARPA. Connect to S1-C.ARPA and go to the (sub)directory "uw". The file "uw.shar" is a text file which contains the entire distribution (in "shar" format). The distribution is also available in nine pieces (each smaller than 64Kbytes) named "uw.shar.1" through "uw.shar.9". I invite the INFO-MAC moderator to copy the UW distribution to the INFO-MAC archives, and I will send the 9-piece collection to the USENET "mod.mac" moderator. -- John Bruner (S-1 Project, Lawrence Livermore National Laboratory) MILNET: jdb@mordor [jdb@s1-c.ARPA] (415) 422-0758 UUCP: ...!ucbvax!decwrl!mordor!jdb ...!seismo!mordor!jdb ------------------------------ Date: Fri, 3 Oct 86 17:36:16 PDT From: <DAVEG@SLACVM.BITNET> Subject: Delphi Mac Digest V2 #47 Delphi Mac Digest Saturday, 27 September 1986 Volume 2 : Issue 47 Today's Topics: DataFrame RE: DataFrame (Re: Msg 12941) RE: DataFrame (Re: Msg 12946) RE: DataFrame (Re: Msg 12949) RE: DataFrame (Re: Msg 12960) RE: DataFrame (Re: Msg 12949) RE: DataFrame Altsys upgrades RE: Printing multiple text files RE: Difference between Mac 512E and Mac Plus RE: Reset & HFS with C compilers RE: Reset RE: C Compilers and HFS Tex for the mac RE: My DataFrame 20 (Re: Msg 12884) LAUNCHING RE: LAUNCHING (Re: Msg 805) RE: LAUNCHING (Re: Msg 806) imagewriter 2.3 RE: imagewriter 2.3 (Re: Msg 13010) RE: imagewriter 2.3 (Re: Msg 13011) RE: imagewriter 2.3 (Re: Msg 13015) MacScheme RE: Useful tips 'n tricks with VersaTerm, Edit and Word Networks RE: Medical/Dental (Re: Msg 12895) Architectural programs LS Pascal RE: TextEdit Behavior Fedit+ RE: Fedit+ (Re: Msg 13070) RE: Fedit+ (Re: Msg 13072) RE: Fedit+ (Re: Msg 13075) LaserWriter cartridge toner RE: LaserWriter cartridge toner (Re: Msg 13080) RE: LaserWriter cartridge toner (Re: Msg 13097) RE: Request for PICT disk file format & Getting grow regions in Windows..

Apple says that (as long as you don't toss anything funny into the box) the Mac is within temperature specs. I've blown out one analog board because the cap at the top of the board exploded (not uncommon, it is near the airflow exit where things are warmest). I've also found that touching the side of the mac is so hot I can't keep my hand there. I don't care what Apple says, I won't run my Mac without a fan -- $80 for the fan vs. $200 for a replacement board if a part is heat marginal is WELL worth it to me. I also expect the cooler temperatures will cause everything to last longer. Apple said the same about the Apple ][, and they were wrong there, too. Minimum configuration Mac's (and ]['s) might get away with no fan, but who uses minimum configurations? And who wants to take the chance?

When i was working at NASA this past summer, we had approximately a 60-70% failure rate on our 512K Macs with HyperDrives. I figured that high a rate wasn't due to defective hardware, so I got a digital thermometer, and a thermocouple, (I DO NOT recommend you do this at home!) and threaded the thermocouple into the machine. I found that a regular 512K machine ran at about 120-130 degrees internally, and a HyperDrive machine, with their puny little fan, ran at about 190-200 degrees!! So most of the problems we were having were due to heat more than anything else. I sent in a purchase request for 10 Fanny Mac units; in the meantime, I homebrewed my own fan unit out of some shipping cartons, a switch, and a 3-inch muffin fan, and some RTV to seal the joints in the box. After some careful cutting, taping, and gluing, I had a fan unit that I could easily lift on and off of my machine, cooled fantastically well, owing to the large plenum chamber on top of the machine, and cost next to nothing! Muffin fans cost maybe $14-15 dollars. I placed this setup on top of my HyperDrive Mac, which had recently been having some real problems, and Voila! The internal temperature dropped to about 80 degrees, and my problems miraculously ended!! To anyone who's interested, I can send more details of how I built my box, and if I get enough responses I will prepare and upload a MacWrite document giving the details. I strongly recommend the use of a fan, either home-built or commercially made; I've seen the Fanny Mac, and it seems to work fairly well, tho' not as well as the setup I described above. STAY AWAY from the internal piezo fans and internal muffin fans, as these produce very little cooling effect, and they disrupt the Mac's natural airflow, which produces internal hotspots.
