30 Years of the Apple Lisa and the Apple IIe

walterbyrd sends this excerpt from an article that might make you feel old: "At its annual shareholders' meeting on January 19, 1983, Apple announced two new products that would play a pivotal role in the future of the company: the Apple Lisa, Apple's original GUI-based computer and the precursor to the Macintosh; and the Apple IIe, which represented a natural evolution to the highly successful Apple II computer line. ... The Lisa introduced a completely new paradigm—the mouse-driven graphical user interface—to the world of mainstream personal computers. (Note that the release of the Xerox Star workstation in 1981 marked the commercial debut of the mouse-driven GUI.) The Lisa’s elevated retail price of $9995 at launch (about $23,103 in today’s dollars), slow processor speed (5MHz), and problematic custom disk drives hobbled the groundbreaking machine as soon as it reached the market. ... Around the time of the Apple III’s launch, Apple was so sure of the new computer's success that it had halted all future development of Apple II-related projects. But by 1982, as it became clear that the Apple II wasn’t going away (in fact, it was becoming more popular than ever), Apple scrambled to upgrade its aging Apple II line, which had last been refreshed in 1979 with the Apple II+. The result was the Apple IIe, which packed in several enhancements that regular Apple II users had been enjoying for years thanks to a combination of the Apple II’s plentiful internal expansion slots and a robust third-party hardware community to fill them."

    For an amazing read look up the BYTE magaxine review of the Lisa. The article takes you on an amazing trip where the writer is trying to describe for the first time so many things we dont even think about.

    IIRC he describes the 'pointing device' (mouse) as "about the size of a pack of cigarettes that moves a point on the screen - The screen then uses small pictures of common tasks to represent your actual desk top.

    Watching them describe 'the desktop metaphor' when they dont know what it is a crazy reminder of just how fast this all happened...

  3. Lisa was better than most people realize by ChrisC1234 · · Score: 4, Insightful

    The Lisa was ahead of its time, and many people don't know that. I grew up with a Lisa (later upgraded to Macintosh XL). For YEARS, my dad would complain how the Lisa could do more than the Macintosh operating system. Even the difference in desktop paradigms (where the Lisa was a document centric system, and the Mac is an application centric system). However, my dad's investment in the Lisas and their quick demise led him to curse Apple and Steve Jobs for a long time. We've still got 1 or 2 systems sitting in an attic somewhere. And I recall a few years ago having come across the whole set of system manuals for the original Lisa (with Twiggy drives).

  4. Lisa was better, its price was the killer ... by perpenso · · Score: 5, Interesting

    The Macintosh was such a superior machine in nearly every aspect that the unsold Lisas had to be hauled off to the landfill.

    I don't know about the Mac being superior. I had the chance to use both, the Lisa had many advantages over the original Mac.

    The problem with Lisa was the $10K price tag. That just put it out of reach of many Apple II developers so a market never really materialized, unlike the Mac which was affordable by such developers.

    Prior to the first native Pascal, and later C compilers, friends and I were actually using 68000 coprocessors for Apple IIs to write Mac software in assembly. A Microsoft Basic program running on the Mac would read the binary from the serial port, poke it into RAM and jump to it. I am not saying this was cost effective compared to buying a Lisa for Mac development, but we had time and no money. One of my friends actually completed a strategy game port from PC to Mac in this manner. I'm not sure but I think it was one of the SSI games. Its not as crazy as it sounds. Core non-UI code could be debugged to a degree on the Apple II's 68000 coprocessor.

    Except he didn't give proper credit. While Xerox had the first commercial sale of the mouse, it was invented by Doug Engelbart.

  6. 6502 assembly ... by perpenso · · Score: 4, Insightful

    I know the feeling. The //e is what I cut my teeth programming on ^_^

    That was my second love, after the II+. Still miss the programming when it was direct and simple.

    I am so glad that I learned assembly language on a 6502. If I had started on an x86 I probably would have had a bad attitude towards assembly like most who did start on x86. To be fair, x86 became a whole lot better once it went 32-bit. However 68000 remains my favorite. Learned it via coprocessor boards in our Apple //e systems. PowerPC was OK, it had its moments.

    Which was the problem with Xerox machines as well. The thing about Apple is that they are selling stuff that sometimes isn't quite ready, from a commodity point of view, to be sold yet, or does not ultimately fit into the way we use computers. Here is what was wrong with the Newton. It was sold as a stand alone device. Some may disagree, but I used both models for a long time. They were very useful. They allowed my to do a lot of things. I could plug it into my network with a standard cable and work.

    Here is what they got wrong. It was not a stand alone device. It really required a bigger more powerful machine to work well. That is why I move to the much less powerful, useful, rugged Palm V. At the end of the day, a partner was more useful than a competitor.

    Apple has gotten that right now. Data can be viewed across a range of devices. Entered anywhere viewed anywhere. Which is the critical difference between the iPhone and Newton. Data Compatibility between the software. Google is also doing a very good job at this using Google Drive. MS still seems to be focused on making sure they receive a license payment for each individual box.

  8. The problem with the Lisa by Animats · · Score: 5, Interesting

    The Lisa got so many things right. A good GUI, a protected-memory operating system, and a hard drive file system. The problem was price. The price problem was due to trouble at Motorola. The Motorola 68000 didn't do instruction backout properly, so it couldn't handle page faults correctly. That was corrected in the Motorola 68010, but the 68010 was too late for the Lisa. So the Lisa had to use a compiler hack to work around the lack of instruction backout.

    Because the 68000 couldn't do instruction backout, Motorola didn't make an MMU chip for it. So the Lisa had a custom MMU built out of a large number of ICs. This pushed the parts count and cost way up.

    Because good hard drives weren't available for personal computers when the Lisa was designed, Apple built their own, the LisaFile. Apple's attempt at hard drive manufacturing produced a slow, expensive, unreliable drive.

    By the time the Lisa shipped, Sun was shipping the Sun I, and the UNIX workstation era had started. The Lisa was in the same price range as UNIX workstations, but the Sun I had a 68010, Ethernet, and hard drives that were expensive but worked.

    If it weren't for the instruction backout problem on the 68000, the history of computing could have been completely different. The Lisa was usable, but overpriced. The original Macintosh was an appallingly weak machine - one or two floppies, a slow CPU, and very little memory. This tends to be forgotten, but the original Mac was a commercial failure. Not until the hardware was built up to 512K and a hard drive was supported did it become profitable. (Or usable.) But it was saddled with an OS designed for 64K of RAM. (The original MacOS had a good GUI, but under the hood, it was a lot like DOS - not only was there no memory protection, there wasn't even a CPU dispatcher. The original Mac was supposed to have only 64K of RAM (most of the OS was in ROM) but shortly before shipment, it was increased to 128K.)

      What is instruction backout?

      When a page fault occurs part-way through an instruction, the CPU has to interrupt execution. After the page has been brought in from disk, execution can resume. But it must resume as if a page fault hadn't occurred. The usual approach is to restart from the instruction that failed, which means that instruction gets done twice.

      The problem is that some instructions aren't idempotent - doing them twice has effects different than doing them once. On some CPUs, an instruction can call for both a memory access and a register increment. If the memory access faults, the register must not be incremented twice. So either the instruction has to be backed out to the state just before it started, or the state of the partially executed instruction has to be saved in the interrupted state. (The M68010 actually did the latter; there were extra words in the state saved on an interrupt to hold data about partially finished instructions.)

      This gets much more complicated in superscalar machines, where multiple instructions have to be undone. See these lecture notes from a CS course at U. Vermont, which discusses "back-out", and its successors. In machines with out-of-order execution superscalar processors, you can't just back up; undoing the state of the CPU on a page fault is a big deal. It works, but it took Intel 3,000 engineers to design the Pentium Pro to do out of order x86 code.
