There isn't a doubling in performance, but it _is_ quite significant. Maybe about a 70% increase in performance.  Besides, for 0 wait state performance, you'd need a cache anyway.

Complete Q700 are best obtained from your dealer or some recent copy of MacWorld or MacUser.  My foggy memory suggests that the most relevant comparison factors vis-a-vis a IIci are as follows:    25 MHz 68040   16 Mhz data path (don't recall this for sure, but it's slower       than Q 950 style machines for sure).   Ethertalk card on-board   Audio in/out   4 MB RAM on motherboard   4 SIMM slots   2 NuBus slots.   More flexible build-in video than the CI.  Uses VRAM.  In comparison, a IIci with an accelerator won't give you   audio or ethernet  or the same video options.   With a 68040 accelerator, CPU performance can be comparable but I   think it ends up costing more.
We have recently obtained a Centris 610 and it has developed an unusual video problem.   Model:	610 with 8 MB/230 HD, 512K VRAM, no cards Monitor:	Apple 16"  When the computer is set for 256 colors and certain operations are done, particularly vertical scrolling through a window, horizontal white lines appear on the monitor (which generally but not always spare open windows).  These lines accummulate as the operation is continued.  If a window is moved over the involved area of the screen and then moved away the line disappear from that area of the screen.  This problem is not observed if the monitor is configured for 16 colors or a 14 inch Apple monitor with 256 colors is used.   I suspect a bad video RAM chip but cannot be certain.  The problem has been apparent since day 1 but has gotten worse.  We were wondering if anyone has seen anything like this, and if so, how to fix it.  Please also respond to azelenet@bigmac.mskcc.org.  Thank you for your help.

My Datadesk Mac 101E keyboard has similar problems.

However, the Mac SE cannot DISPLAY grayscale on its screen or any attached video because that ability is not in the ROM.  So, while you might be able to PRINT grayscale, you'd have a hard time SEEING the grayscale image you want to print.  Doug

It would be an extremely hot idea...at least with the current Alphas. The available Alphas run up to 200 MHz. But they produce quite a bit of heat.

Has anyone had any problems with their Duo Dock not ejecting the Duo properly?  When I first got it, the Duo would come out of the Dock a couple of inches when ejected, and I had to pull it the rest of the way. Nowadays (and I've had the system for 4 months), the Duo doesn't come out *at* *all* - despite the fact that the mechanism makes all the appropriate noises, and I have to grab hold of it and pull it out myself. Is there a simple fix for this, or do I have to return it to my Apple Dealer, where it will languish for weeks while I have to make do with no colour display, no VRAM, no floppy or SCSI etc.   (BTW, it's not that the Duo is locked into the Dock - it just doesn't want to slide out any more).

Both machines were running System7.1, had a 14" RGB.  Don't know what the caches were set to. Neither machine had an FPU  It appears that the Centris610 is quite a bit faster than the LC III:  		Centris610		LCIII  CPU		13.01			6.92 Graf		15.67			7.69 Disk		2.22			2.44 Math		25.57			10.19  P.R.

stubbs@hawk.cs.ukans.edu (Jerry Stubbs) writes: > The electricy consumption will go down if you turn them off overnight, > along with heat.  	I wonder how hard it would be (i.e. what it would add to the cost) to design desktop machines with a power saver feature built in which would reduce power consumption automatically if the machine is idle for more than some amount of time.  This is pretty standard in portable machines, and the same kinds of tricks could be played; spinning down disks, turning off screens, reducing clock speed, etc.  The advantage of this over just turning the thing off would be 1) you don't have to remember to do anything and 2) the machine is still available over the network.  	The tricky part might be in defining what constitutes inactivity. Certainly, you don't want to wake up from sleep mode just because somebody pinged you, but you do want to wake up (at least the CPU) if somebody logs in via a telnet connection.  	I wouldn't worry too much about wasting electricity in the winter months; that energy is just getting turned into heat.  It may not be as efficient a way to heat a building as the central heating plant, but it's not too bad.  In the summer though, it's a disaster.  Not only are you wasting that power, but you're probably also running the air conditioning to get rid of the waste heat.
>If anyone has any information about the upcoming new computers >(Cyclone and Tempest), I am in need of some info. Anything would be >greatly appreciated.  >-Shawn >breedsa@wkuvx1.bitnet  According to MacWeek of 2-22-93:  The Cyclone will come in the same metal minitower case as the Quadra 800, while the Tempest will share the low-slung case of the Centris 610. Apple will offer a miniature video camera that can be mounted above the user's monitor or moved about on the end of its cable to take pictures of objects or documents. Taking advantage of the 32-bit digital signal processor (DSP) built into the systems' logic boards, the camera will be able to put an image measuring 360 by 288 pixels, with 256 gray levels, on the screen.  Users will be able to install supplementary lenses that can record detail as fine as the wire bonds on an integrated circuit. The camera is expected to cost between $150 and $250.  The systems will ship with all the software needed to put Apple's Casper voice-recognition technology to work; users apparently will have to purchase an operational high-fidelity microphone.  The two models will talk as well as listen. A new system facility called the Speech Manager will convert text strings sent by applications to phonemes and then pass them to a speech synthesizer.  The Cyclone will include a 40MHz '040, three NuBus slots and support for up to 128MB of RAM. The Tempest will use a 25MHz LC040, lacking an FPU, and hold up to 68MB of RAM; it will have a single slot that will require a NuBus adapter and have room for only 7-inch NuBus cards. Users will be able to update the Tempest's process but not the Cyclone's.

Reynolds" <jpr1@lehigh.edu> Subject: When you're not using it, turn it off! Date: Mon, 22 Mar 1993 06:50:14 GMT Lines: 53  Research has shown that the majority of the time that the United States' 30 to 35 million personal computers are on, they are not actively being used.  In addition, 30 to 40 percent are left running at night and on weekends.  Computer equipment is now the fastest growing private-sector use of electricity.  Computers alone are believed to account for five percent of commercial electricity consumption, and may account for ten percent by the year 2000.  If you are one of those who leave them on after you're done, it would be a big environmental benefit if you would just TURN IT OFF when you're not using it.  It only takes a second or two to do.  Also, the majority of the power your computer uses is not consumed by the computer itself, but by the monitor.  If you can't turn the computer off, then please just TURN OFF THE MONITOR.  The U.S. Environmental Protection Agency has formed an alliance with computer manufacturers to promote the introduction of energy- efficient PCs that "power down" automatically when not being used and thus reduce the air pollution caused by power generation.  These new computers will save enough electricity to power both Vermont and New Hampshire and save up to 1 billion U.S. dollars in annual electricity bills.  Look for the special EPA "Energy Star" logo when you buy computers.  They should be available in one to two years.  According to the EPA studies, the energy saved will prevent CO2 emissions of 20 million tons annually, the equivalent of five million automobiles.  Also, 140,000 tons of SO2 and 75,000 tons of nitrogen oxide emissions will be saved; these are the major pollutants responsible for acid rain.  Please do your part ... be responsible.

Macintosh IIsi, 3/40, 80ns. Clock-upgraded IIsi works well at 25MHZ, however, does not work with Nubus adaptor and 1400k disk even though it can read/write 800k disk at32MHz.

I have a new 25 MHz Motorola 68040 that I am willing to sell if I get a good enough offer.  It is still in its static free sealed package.  If I don't get a good enough offer, I will use it to replace my 68LC040.  Any takers?    Supposedly you can get one of these for $375.  However, at the moment the demand is higher than the supply so I think $400 is a good round number. I will pay shipping, of course.
I have some questions about this subject.  I like to leave my computer on if I think I'm going to be using it withing the next 2 or 3 hours, but I get sick of my Dad constantly coming up to me and asking "Why is the computer on if you're not using it?"  I also wonder about my computer being harmed by fluctuations in voltage from other things (garbage disposal, etc.)  Here are my questions:   How much harm do voltage fluctuations cause?  My computer does not share a circuit with anything big but our my light dims when a refrigerator comes on or the garbage disposal is turned on (whose doesn't?), and also when the washing machine does anything.  All these things cause a drop in voltage which is harmful to a computer, right?  I also notice the fan in my System Saver turning at different speeds.  Is it safer to turn it off and back on when I want to use it or to leave it on?   How much electricity does my computer use?  I have an Apple IIgs (ne flames), with a Kensington System saver GS (1 electric fan inside), an AppleColor RGB monitor, and an EXTERNAL 3.5" HD (1 fan and its own P/S).  How do I translate this into Kilowatt-Hours?  Also, how much of this is used by the monitor?   Does the monitor use considerably less juice when the screen is totally black but still on?   Many computers spin the HD up and down constantly to save power.  I always thought this was harmful to the HD and defeats the purpose of leaving the computer on in the first place (except portables).  Is this true?   Thanks for the Info.  I think this will help lots of people.
