There's this old SE here. It's got the older-style fans that remind me of a house-ventilator. A cylindrical drum instead of the bladed rotor I usually see. Anyway, the SE makes this loud buzzing noise due to vibration somewheres. If I remove the screws and loosen the front from the back, it quiets down. I can only assume that the fan housing from this goofy thing is touching the back of the case and vibrating against it.   Anyway, any suggestions for where to get replacement fans and how to "stealth" this guy? Your experiences welcome.....
Hi!  My co-worker has just attached a magneto-optical drive to his mac. Works Great for him.  However, he tried to turn on file sharing, but it wouldn't work.  Had some message about "Not all volumes are shareable" ???  So - has anyone had success in sharing MOs?  If so, please tell me how!
A friend of mine has problems running Spigot LC on an LC III. His configuration is:  Spigot LC / LC III, System 7.1 Video Spigot Extension 1.0  I would appriciate if I can get any postitive/negative experience with this setup.    Thanks,

The accelerator costs about $1400 whereas the upgrade costs $2131 (just quoted from my dealer).  However the Q700 upgrade gives you very fast built in video that supports monitors up to 21" with 8 bit depth and up to 16" at 24 bit depth (with additional VRAM).  It also has a SCSI port capable of a much faster throughput than the CI, which makes a big difference if you have a fast hard drive.    If the improved video and SCSI features are important to you, you're better off getting the Q700 upgrade, otherwise save some money and get an accelerator.

I have  a strange piece of equipment to unload. It is a Ether+ SCSI interface. Apparently, it can be plugged into a SCSI port and from there to an ethernet. That way you save a slot. Nifty. Well, I assume you people know more about it, so, judging by the $350 price tag new, I'll ask, say, $75? Anybody interested?

I'd buy an external and save about  $350.   there is a manufacturer that still makes INTERNAL HD's for the portable,  they're listed in some of the catalog "magazines" for apple stuff you can  find at bookstores. If I see it again I'll post it. But, again, you might  want to just add a small lightweight external HD built for the  powerbooks. You'd be able to use it with a new computer some day.

I am trying to put a 40MB drive from my LC into a case.  It is a Conner CP3040A.  I can't figure out which jumpers are the SCSI ID jumpers. Is anyone familiar with this drive?  At the end of the drive (oposite the 50 pin pibbon connector), there are eleven pins which look like this:           o o o o o   o   1           o o o o   o   2           L5  CR12   C37  where the "o" are pins, and the "L5 CR12 C37" represent some of the silk screen notation near these pins.

Does anyone know where the SCSI ID A0,A1,A2 pins are, and where the drive activity light LED should be plugged into?  		-allan
I was reading a review of the Centris 610 in this  months MacWorld and the reviewer said that for  $4 you could make an adjustment on the clock speed of the chip and change it from 20mhz to 25mhz.  I  haven't heard of this before, and I don't think that this is the 040 chip replacement (with fpu) that I have seen so much talk about.  Anyone have any ideas? cwera@du.edu

Battery powered devices like the PowerBook are sometimes more sensitive to  serial port weirdness.  I had trouble with connecting my Mac Plus to an HP 95LX handheld.  Everything else worked okay on that port, but not the HP. (it runs on two penlite batteries).  It turned out that the plus (by accident or by  design flaw?) was putting a 4 volt bias on the serial port that was doing  weird things to the HP (which has only 3v dc!).  The HP worked fine when  connected to the printer port.    Does your PB screen get dim or anything when connected to the device?  Have you  tried using the printer port?  Good luck.   --jamie

Well the monitor is consistently the largest power drain on your electric bill when you are looking at your computer set-up, especially if you have a large (16" or greater) color monitor. Generally what I do is leave my Mac on all the time, except for the occasional resart or syetem crash, but I turn my monitor off each night before I leave my office. I also turn off After Dark when I do this, since there is no reason to have the screen saver running when there is no picture being displyed on the monitor's tube.  >Actually, I thought Macs were suppoused to be restarted once a day.      Really? What makes you think this? The Q700 file server in my office has been on for the last 2 months, straight, and it hasn't had any problems. (Note: I also keep the monitor for the file server turned off when I'm not actually working on the server itself.)
Anyone have a price quote/vendor for the vx to centris 650 upgrade? I've been quoted a price of $2401 till August 15th after which it will cost $2732.  This of course doesn't include the trade-in rebate of $1300 for the vx board.  Thus for $1101 one gets a Centris 650, 8 meg onboard with both the FPU and Ethernet.  Anyone else have any info? This price is from the University of Illinois micro-order center, are there any other vendors who offer similar prices?   johann
Hi, I just test installed kanjitalk 6.07 on my IIci  and got a black screen, a way sick looking mac icon, and when hitting the programmers reset, a tone sequence that I guess is the infamous "tones of death."  I was able to reboot off a floppy, removed the japanese system, and set up the system folder on the hard drive to get system 7.01 back. Now have no overt problems with the mac. Any idea what caused the tones?  I forget the numbers but 7fff comes to mind. If it is some self diagnostic, why would an older system version catch it, and not 7. ? (I'll be moving up to 7.1 and worldscript by-and-by) Thanks in advance, Hiroki

I have an external hard drive I wish to use as startup disk. problem is, when I switch on the mac, it boots on the internal HD, but when I restart  (warm boot) the mac, it boots from the external. how do I make  it boot directly from the external ?  please email replies if possible.  thanks in advance.

In the May issue of C't Magazine was an article about upgrading 040 models of apple. They simply change crystals and add a fan. Hammerhead: Centris 610 was able to work with 25 MHz (cooler prefered)             and for 1000 DM you get an 68040 (33MHz) which works with the             appropriate crystal at full speed. (extra cooling required)                 Centris 650 like Quadra 700 with extra cooling 33MHz works on             most machines and for real power enthusiasts they used a             Quadra 950 at 40 MHz wow!

I guess I might believe anything. > >Whats the scoop on this standalone "drive activity" every 20 sec?  I can only comment on thermal recalibration in general. Some new drives perform it in order to increase overall integrity of data writes. Basically, the firmware instructs the actuator to perform a test to see if the data tracks are within a certain physical tolerance, since when the media heats up or cools down, *some* track drift is inevitable, and the drive has to monitor it. This becomes especially critical at very high recording densities, and so was used primarily on very large-capacity mechanisms, but it seems to be finding its way into more smaller drives as a way of boosting the drive's long-term reliability and MTBF ratings.  I first became aware of thermal recalibration when it was pointed out that the technique conflicts with prolonged write times when digitizing, say, audio or video to hard disk. Some manufacturers explicitly state that drives with thermal recalibration are NOT to be used for applications that have prolonged disk writes.  Hope this helps.

I believe it goes or will go: 680060 powerPC Pentium 680040 486 680030 386 680020 286=680000  In a resent article in one of the macMags I think a 50mHz 030 accelerator was  slightly slower than a 25mHz 040 accel. But, this is using a system designed  for the 030. So, It stands to reason that a system designed for an 040 ie  quadra) would do better. So overall I'd figure 040 = 030 * 2.5 or so.     Along the same lines the new POwerPC stuff is supposed to run the system  at the level of a fast quadra, but system 8 or whatever will allow 3 times the  speed of a 040 in the powerPC based systems. and wait for the 680060. I think  it laps the pentium.  pro-life pro-women
