Thanks for the enlightening post.  Is there a Technical Note on this?  The desktop machine I was referring to was actually not a Mac, but rather, any of various workstations that use the 68030@25MHz, such as old Suns or old NeXTs.  I used to own a NeXT 68030 cube.     But I will try rebooting without extensions to see what kind of a speed difference I get with my powerbook Duo. I did notice an extreme slowdown to unusability with a Mac Plus after installing system 7 on it.  Why does the OS suck up so much CPU power?   Also, you're right--software does make a HUGE difference.  I have the misfortune of using MS-Works on my Duo.  When editing relatively small (40K) files, cut or copy takes several seconds, often more than 6 seconds!!  This happens with power cycling turned off.  As usual, MS software is maggot-infested feces.  I'm getting Nisus to replace it for my text editing.

Okay, we're getting REALLY hypothetical >now...   It would also be great for another reason - when not docked, it could serve as an ARA server to the large internal HD, your corporate email, etc.  In a pinch, you would also have two machines, instead of 1.5.  If they could couple that thought with RocketShare, and let you use both the '030 on the PB and the '040 on the dock, it would be a mighty powerful dock.  --

Is anyone out there using a greyscale handscanner. I'm thinking about buying one. Is the inexpensive Logitech pretty good. I don't need super high quality scans- but want it to be worth the $$$$.
I have read one report of a brave soul who rewired the 40 mhz clock and a higher speed clock oscillator's outputs through a double throw switch to allow different  speeds. There was no mention of any attempts to switch speeds on the fly but if the SI uses timing loops anything like a Quadra for accessing its floppy drive, dynamic switching will wreak havoc. A Quadra must reboot after having its clock speed significantly changed or it will be unable to properly access its floppy drive.
The subject says what I would like to do, here are the details:  I have a 512ke with the MacRescue upgrade board that makes it the equivalent of a Plus (System 7 and MacEnvy both identify it as such).  The MacRescue board clips onto the 68000 on the MB.  It also has a 68000 itself.  Periodically I have to remove the clip (not an entirely easy thing to do) and clean the "legs" of the 68000. Larry Pina's book asserts that this is occasionally a problem with snap on upgrades:  the 68000's "legs" will oxidize, causing  unusual system errors.  Well, that's me.  So, I would like to do something permanent, and I think it would be fairly easy to put a socket in where the 68000 currently is, and modify the MacRescue board to plug in.  What I'm not 100% sure of is whether it will work.  It seems to me that the two 68000s aren't acting independently; so removing one shouldn't have any effect on the performance of my Mac.  I'm about 97% sure.  Will someone provide the extra 3%?

I can't remember trying to rebuild the desktop with it, however it did give me a strange problem.  When I held down shift during startup to disable all extensions, nothing happened. I tried it with another keyboard, using the same adb connector cable- and it worked with the other keyboard. The shift key on the Datadesk keyboard worked well otherwise. I checked the dipswitches and they are fine.  Try disabling your extensions and tell me if it works.  I am annoyed with Datadesk.  I sent them the keyboard in the mail for inspection/repair/replacement.  The technician on the phone said they have a 10-14 day turn around time- meaning you should receive the inspected/repaired keyboard in that time.  Well, they have had the keyboard for over 3 weeks and I still have gotten very little info from them about it. It's annoying because it cost me $12 to send them the keyboard (they do not refund the money) and their costumer service lines are toll calls. Tell me if you have a similar experience.  -David
A question in general about displaying NTSC through a Mac.  If I understand correctly, the Video Spigot can display NTSC in a small window as well as capture the data in Quicktime format.  However, if I want to use a larger window, what are my options? Perhaps I misunderstood the Video Spigot review...    Also, I am not interested in Quicktime.  I would merely like to use my Mac as a television from time to time.  I have a nice Sony 1430 monitor, and I would like to use it as a second TV when my wife is watching sitcoms on our regular TV.    Perhaps some of the video cards for the Mac accept NTSC input? I have a IIsi, and I am willing to buy a NuBus adapter.  Thanks in advance for any help,
The article was probably referring to changing the clock oscillator in a manner similar to that done on Quadra 700's and IIsi's. I haven't read a report of this actually being done on a Centris 610 but supposedly this also works on Q900, Q950 and centris 650 machines.
The internal HD in my LC disappeared for a day last week, and I'd like to hear any (reasonable) theories folks can suggest for what happened.  It is an LC, with 10MB of RAM and an 80MB internal drive, running system 7.1, with a few SCSI devices in a (so far as I know) properly terminated chain.  I had shut down the system for a day-- I was out of town and we sometimes have thunderstorms this time of year-- and upon restarting got a blinking question mark.  I booted from a floppy and saw that my external HD seemed okay, but there was no sign of the internal.  I installed a system folder on the external and was, indeed, able to boot from it.  I tried things like Disk First Aid and Silverlining, to inquire about the internal drive.  They either could not find it or got errors in trying to talk to it. (Silverlining claimed it was a Connor drive, but it is a Quantum... )  Well, I'd backed things up, so I was able to work.  But, at some point I noticed that the internal had reappeared.  Now, Disk First Aid says that all's well, etc.  Things seem to be fine.  But, what happened?  Was this a warning that something (the internal HD or something else) is about to die?  I'm definitely nervous.  And, if this is a signal that the internal HD is sick, is it true that I can only put up to a 127MB drive inside an LC?  Some folks have claimed there's a limitation in the LC (other'n size or power) while others (and that includes LaCie, over the phone) say anything that fits is okay.

Just a quick summary of recent findings re. high speed modems. Top three contenders seem to be AT&T Paradyne, ZyXEL, and US Robotics. ZyXEL has the biggest "cult following", and can be had for under $300, but I ignored it because I need something with Mac software, which will work without any tweaking.  The AT&T Dataport earns nearly unanimous praises for reliability. They are backordered at the moment, probably because of the special $299 price in effect until May. Its fax capabilities are worse than that of the other two modems. WARNING: AT&T ads say that the modem comes with a Mac kit (cables & all), and has lifetime warranty. This applies *only* when you order directly from Paradyne! I called ElekTek (one of the distributors), and they wanted to charge me $16 for cable, and gave only 1 year warranty...  USR Sportster for the Mac is also highly (but not as highly) recommended; it's only $250 from ClubMac, and if you are willing to roll your own cable and don't care about the FAXstf software, you can get the generic model from PC outlets for $190.  All this assuming that you don't have a rich uncle, and can't afford a Motorola Codex...  :-(    I ended up ordering the Dataport; we'll see how it works in two weeks or so.

I also use Retrospect, but I noticed that Central Point Software's "MacTools Backup" also supports the Apple tape drive under 7.x.  The Apple tape drive is quite slow, so the advantages of Retrospect relative to the simpler MacTools Backup are less significant than  might be the case for someone backing up a large server to a DAT drive.    Used Apple tape drives are going for ~$100, so it might make less economic sense to pay an extra ~$140 for Retrospect when MacTools  is cheaper and includes other worthwhile utilities.  Retrospect is nice, though, and I'm probably going to upgrade to 2.0.
>But Apple HD SC says "Unable to locate a suitable drive on SCSI"...  >what's he doing wrong?
The si has a single expansion slot, that can be either PDS or Nubus, but not both together. The card lies parallel to and above the motherboard & HD and requires an adaptor slot to do this. There are Nubus and PDS adaptort cards. Thus, what kind of slots you have depends on what kind of adapter card you have. With the exception of the Radius rocket, all NuBus cards I know of work in the si. PDS slots and thus cards are Mac specific, thus not all PDS cards work in all Macs.

My mac monitor displays about 20 vertical lines when I use it. It means that either my display memory goes wrong or monitor is bad or video card is bad.    I checked my monitor, it works fine with other Mac.    I checked my video card, it's also fine.    I replaced all the RAMs, it still didn't give me right answer.    Hence I assume something wrong with some part of my motherboard.     I don't know hardware architecture of the Macintosh.     Can anyone tell me what's the problem ????     It's a Mac IIcx.

Does anyone work with the A/ROSE card?  We have the problem that after certain crashes the card disappears from the system, and lets crash the Mac then.  Okay, we don't use the card quite like one should, because we simulate errors in the 68000. Before every instruction some specified registers are masked, eg. to simulate a stuck-at-1-error in certain bits.  Normally, the "crash instance" of A/ROSE notices a crash, sets a flag and stops working. By reading the mentioned flag the Mac can notice a card crash. That works fine for almost all crashes, but as said, sometimes the card doesn't set the flag and disappears from the system.  The documentation of A/ROSE does not tell us anything about its behavior when crashing, and so at the moment we are trying to understand by analyzing the assembler code, and that's both frustrating and lengthy.  So, can anyone help? Please only reply via email, as I don't read this group. --   ---------------------------------------------------------------------------      _                   Department of Computer Science IV     / \     |\/|         University of Dortmund, Germany     \_/laf  |  |aennig   e-mail: maennig@veronica.informatik.uni-dortmund.de  ---------------------------------------------------------------------------  "In the beginning God created Adam ... ahem! ... atoms.

I have an SE/30 with a 80 meg HD which dates back to April 1989.  When I originally purchased it, I experienced the failure to boot problem.  This was fixed soon after by a ROM upgrade on the hard drive.  Lately a similar problem has been occuring.  When the computer is powered on the HD light flashes a few times and then I am given the "no disk to boot from" icon.  However, upon turing the computer off and on again the drive ALWAYS boots up just fine.   Furthermore, if instead of turning the power on and off I press the reboot  button the same problem occurs.  But, as I said, turning the power off and on always works.  This problem is different from the 1989 boot problem in that before it often required several power off and ons to get it to boot.  Does anybody have any suggestions as to what the problem is or how it can be fixed?  I'm wondering if it's getting old and requires more time to  "come up to speed" now.  Is there a PRAM or SCSI setting that allows me to tell the computer to wait a little longer before  trying to access the HD?  Thanks!

Apple has really confused people with this whole thing. I think we'll be answering this question for about the next year or so. There is no "option" to get an FPU on a C650. What you have is a choice of CPUs: there is the 68LC040 that does not have an integrated FPU like the full '040 and is only present in the base 4/80 model of the C650 (AppleUSA). And there is the full '040 which you get when you order anything other than the base 4/80 configuration. Therefore, since you have ordered one of the 8MB versions with on-board Ethernet models you will not be getting the LC040. But even if you wanted to have the LC040 you wouldn't be able to order a C650 with 8MB RAM, on-board Ethernet and an LC040. It's not an "option."     Also, a note to people out there that have 4/80 C650s and C610s thinking that there is an optional FPU, the '040 class chip cannot recognize an external FPU, so there is no socket on the motherboard for a FPU chip and you cannot go out and purchase an FPU on a PDS card or something like that. The only way to get an FPU in these machines is to replace the LC040 with a full '040. And if you have a C610, you will not need to worry about a heat sink if you do replace the LC040 with the full '040, but if you have a 4/80 C650 you do need to have a heat sink.

Well folks, after some thought the answer struck me flat in the face:  "Why would Apple release a Duo Dock with a processor of its own?"  Here's why- People have hounded Apple for a notebook with a 68040 processor in it. Apple can't deliver that right now because the 040 saps too much power, radiates far too much heat, and is too large for a notebook. How does one get around that without designing a new chipset? Use existing PowerBook technology to your best advantage. The Duo Dock gives Apple a unique ability to give users that 040 power in a "Semi-Portable" fashion. By plunking the 040 into the Dock, you've got "quadra" power at your desk. On the road, that 33mhz 68030 should be able to handle most of your needs. Okay, not the BEST solution, but its an answer to a no-win situation. :-) So, does this mean one will be able to use the PowerBook's processor in parallel to the dock's processor? Okay, we're getting REALLY hypothetical now...
