A Review of the 128KB Macintosh

bfwebster writes "The physicist John Wheeler famously quipped that 'Time is nature's way to keep everything from happening at once.' The web flattens time by making more of the past accessible. Here, then, is a reprint of BYTE's official review of the original 128KB Macintosh from the August 1984 issue. The article highlights the radical break with other PCs that the Mac represented, while at the same time giving the first real warning of Steve Jobs's least-productive tendency: pre-emptive and often arbitrary constraint of end-user options (e.g., no memory expansion on the 128KB or announced 512KB Macs, even though the 68000 processor had a lovely, flat 16MB address space, as opposed to Intel's 808x segmented hell)."

    Actually the upper limit on early models was 4 megs, not 16 megs. Bits 30 and 31 were mapped into ROM and hardware addresses (respectively, if i recall correctly).

    Still, a great machine. I bought one in April 1984 and was a Mac freak until System 7, at which point I switch to Windows. Back then the OS was just stagnating. Once boxes with OS X came out, I went out and got an iMac and fell back in love with Macs.

      That'd be bits 22 and 23. (If the 68000 had had a 32 bit external address bus, it'd have been able to address 4 gigs, not 16 megs); but, in any case, I think the article was talking about the 68000's maximum address space, not the Mac's - the criticism, after all, was about how Apple was making poor use of the 68000.

      If you think that was bad BTW, the Sinclair QL had a 68008, which had an external 20 bit address bus (maximum of 1M, like the 8088); Sinclair decided in its infinite wisdom to put all the perpherals in the top 256k or so giving the machine the same 640k RAM limit (because RAM started at 128k) as the PC and ensuring that, if they ever came out with a better device, and it was to have some compatability with its predecessor, there'd be a hole right there in the memory map.

    The many facets of a slightly flawed gem

    The Macintosh

    Photo 1: The Apple Macintosh computer
    Few computers - indeed, few consumer items of any kind - have generated such a wide range of opinions as the Macintosh. Criticized as an expensive gimmick and hailed as the liberator of the masses, the Mac is a potentially great system. Whether it lives up to that potential remains to be seen.

    Personally, I think the Macintosh is a wonderful machine. I use one daily at work, and then at night I play with the one I have at home. Or, at least, I try to play with it. You see, my wife - who for years resisted all my attempts to introduce her to computers - has fallen in love with the Mac (her words, not mine). She uses it to type up medical reports, notes on her clients, and personal letters. In fact, she's suggested that we get a second Macintosh so that we won't have to fight over the one we have.

    The Macintosh is not without its problems. Resources are tight - it needs more memory and disk space - and software has been slow in coming to market. Many have criticized its price ($2495). In fact, there are indications that Apple considered a lower price ($1995) and then rejected it. It doesn't seem to have hurt the Mac's market - people are still buying them faster than Apple can make them - but there's the potential for backlash if the machine doesn't deliver on all its promises.

    Whatever its problems and limitations, the Mac represents a breakthrough in adapting computers to work with people instead of vice versa. Time and again, I've seen individuals with little or no computer experience sit down in front of a Mac and accomplish useful tasks with it in a matter of minutes. Invariably, they use the same words to describe it: "amazing" and "fun." The question is whether "powerful" can be added to that list.

    Photo 2: The Macintosh dot-matrix printer
    In an industry rapidly filling up with IBM PC clones, the Macintosh represents a radical departure from the norm. It is a small, lightweight computer with a high-resolution screen, a detached keyboard, and a mouse (see photo 1). It comes with 128K bytes of RAM (random-access read/write memory), 64K bytes of ROM (read-only memory), and a 400K-byte 3½-inch disk drive. If you throw in an Imagewriter printer (see photo 2 and figure 1) the system costs $2990. The processor is a Motorola 68000, running a name-less operating system (see the text box, "A Second Opinion" on page 248 for a fit description). It has absolutely no IBM PC/MS-DOS compatibility, and it would appear Apple plans none.

    The Display

    The display is small (9-inch diagonal), but it has very high resolution (512 by 342 pixels). Every pixel is crisp. Several things make the display unusual. First, the Macintosh has no "text mode." Instead, the display is always bit-mapped graphics. Second, the display is black-on-white rather than amber-, green- or color-on-black, giving it an ink-on-paper effect. Third, the pixels are equally dense both horizontally and vertically, eliminating the "aspect ratio" problem that plagues other graphic systems. (In other words, a box 20 pixels wide and 20 pixels high will be a square.)

    Figure 1: A sample printout from the Macintosh using its printer and the MacWrite word-processing program. The printout was obtained using MacWrite's high-quality output mode, as opposed to the draft and ordinary quality modes. The output here is shown at 100 percent of actual size
    The effect is excellent. The display is clear, crisp, easy to read, and easy on the eyes. Because all text is graphically generated, the "what you see is what you get" word processing is available (with multiple fonts, sizes, and styles). Embedded drawings and proportional spacing are also possible. Some criticism has been made about the lack of a color-graphics capability. Frankly, I am unconvinced of its necessity. Most applications I have seen use color graphics as a substitute for detail, and the Mac

    I mean think about the Mac compared to a PC of the day. WHY would you buy a PC in 1984?

    PCs had color, Macs didn't until '87. PCs had hard drives, Macs didn't. From Wikipedia:

    "The limitations of the first Mac soon became clear. It had very little memory, even compared to other personal computers in 1984, and could not be expanded easily; it lacked a hard drive or any means to attach one easily. Although by 1985 the Mac's base memory had increased to 512 kb, and it was possible, albeit inconvenient, to expand the memory of a 128 kb Mac, Apple realized that the Mac needed to be improved."

    I was certainly using PCs with hard drives in the summer of '85, and remember doing the floppy shuffle on a Mac the summer afterwards.

    The NeXT had it's share of problems. Objective C has never caught on. The original version's magneto-optical drive was a total disaster (completely unreliable and dog slow), as was the lack of floppy disk (which was important way back in 1990 when it was released, at least in the University segment, where I encountered NeXTs).

    Perhaps the biggest problem was the price. At $9,999 it was just too expensive for the consumer. Give the cost, it really isn't comparible to the Mac or the Amiga.

The Apple Image Writer was no champion of high resolution output. It used the some 15 pin technology of those other printers, but the Mac used bitmap mode instead of text mode. The result was pretty equivilent. No unless you got the Laser Writer could you really start calling it desktop publishing.

    You are right thought: The Mac was the first personal computer to enable the avaerage Joe to produce documents with multiple fonts, and embedded graphics. But by saying the other computers had nothing more than Notepad is a falacy. There were a great number of word processors, from Scripsit, to WordStar. You couldn't embed graphics, and everything was displayed in text mode; however, you could choose fixed pitch, variable pitch, italics, bold, superscripts and subscripts. Everything you need to actually write a document.

    Apple Macintosh's two great advancements for the home computer were the GUI and desktop publishing.

    Countries with 50 cycle mains have actually had square pixels since anyone thought to use a TV screen as a computer monitor. The TV screen has to refresh in sync with the power, since the electron gun beam is getting weaker and stronger due to the CRT heater getting warmer and cooler as the voltage rises and falls; but as long as the peaks and troughs are in the same part of the screen each time, you won't notice. The studio lights are also similarly affected. So in the UK, Europe and Australia, TV has 25 pictures of 625 lines a second. The greater number of lines allows for more-nearly-square pixels.

    This, incidentally, is why PAL Amigas have 256 or 512 line displays as opposed to 200 or 400. At least they do on most boots ..... there was some obscure glitch which could force them go to 200 lines, and I confidently predict that someone will respond with an explanation.
