Greetings. I saw the announcement of the Mac IIx in Bay Area Computer Currents. I saw mention of the 68030, the 68882, and the "SuperDrive", but I saw no mention of processor speed. Does anyone know how fast this puppy runs? -Jonathan Dubman Overworked UC Berkeley Student

Does anyone know how fast this puppy runs? Here is the appropriate paragraph direct from Apple's press release: "The combination of the 68030 microprocessor and 68882 math co-processor running at 16Mhz provides users with an additional 10-15 percent performance improvement over the Macintosh II. In addition, virtually all Macintosh II-compatible software runs without modification on the Macintosh IIx." Not a great deal of improvement, is it? About the same as the SE was supposed to have over the Plus.

Gosh, I wonder if that means it will only take 17 seconds instead of 20 seconds to boot! WOW! Actually, this is in line with estimates from some hardware-knowledgable folks who have posted about the differences between an similar clock-speed 68020 and 68030. I thought that putting the ROMS on a SIMM board was the cutest thing about the new board.

I know, I know, only a rough indication but nevertheless:
Someone I spoke to said the IIx plowed its way thru an Excel sheet
with something like 1500 records (no idea of calculations) used in
just about 30 secs. The Mac II refused to perform the calculation...
Just when you thought the Mac II was a _power_ machine ... ;)

The speed of the IIX is only 16mhtz. What a drag I was hoping for 33mhtz. rob

What's a superdrive? I have a Mac II, and I want to know what I'm
missing out on.

The story on the Mac IIx's speed is somewhat incomplete. Here's the info. direct from Apple's AppleGram: The Macintosh IIx is the first CPU from Apple to feature the latest technology from Motorola, a 68030 microprocessor and 68882 math co- processor. This combination improves the performance of most applications by an average of 10 to 15% over the Macintosh II, and the performance of certain floating-point calculations, such as logarithms and trigonometric functions, by up to 200%. Since someone asked about the super drive, here's the relevant info. on that: The Macintosh IIx is the first computer to come equipped with Apple's new 1.4MB floppy disk drive, the FDHD (Floppy Disk, High Density), making it the ideal computer for campuses that want to use Macintosh alongside MS- DOS or Apple II-compatible computers. The FDHD reads and writes to the major 3.5" disk formats: the Macintosh Group Code Recording (GCR) 400K, 800K, and Modified Frequency Modulation (MFM) 1.44MB formats; the Apple II GCR 800K format; and MS-DOS and OS/2 MFM 720K and 1.44MB formats. Using the Apple File Exchange, located on the Macintosh Utilities disk, you can now use your Macintosh IIx to access and share files and information stored on other types of computers within your workgroup. ----Chris

ROM slots may be a good idea in the long run-- no motherboard swap needed if apple makes the changes they're probably working on for newer OSs. Actually, the real advantage of the '030 is not to the customer, but to the manufacturer. They don't take up more board space to put an MMU in (or need to beef up power either). I also here that the '030's built in MMU kills a wait state that the '851 chip introduced when it was added. -dave falkenburg -- Dave Falkenburg @ University of Michigan Computer Aided Engineering Network Internet: falken@caen.engin.umich.edu UUCP: umix!caen.engin.umich.edu

OK! how many of you owners of the no longer state of the art Mac IIs are going to run right down to your dealers and plunk down the >$3K it takes to upgrade your old computer to the new IIx configuration???? Who will be the first on the block to have a 10 to 15% faster TRANSISTION Mac??? TeriAnn

I am not sure, but I did read that the 68030 runs at 16 MHz as well. I do not know the details about why it computes faster than the 68020. Joe Peterson peterson@applicon.com

Byron, do you know if they have removed the wait-states from the memory accesses or done anything to speed up the NUbus? Both of these are fairly serious bottlenecks on the current design. Also, any sign of a DMA chip, or do they still not want to do multitasking? Jon
