The Lisa



The Lisa is a personal computer designed by Apple Computer, Inc. during the early 1980s. It was the first personal computer to offer a graphical user interface in an inexpensive machine aimed at individual business users. Development of the Lisa began in 1978 as a powerful personal computer with a graphical user interface (GUI) targeted toward business customers. In 1982, Steve Jobs was forced out of the Lisa project, so he joined the Macintosh project instead. The Macintosh is not a direct descendant of Lisa, although there are obvious similarities between the systems and the final revision, the Lisa 2/10, was modified and sold as the Macintosh XL.

The Lisa was a more advanced system than the Macintosh of that time in many respects, such as its inclusion of protected memory, cooperative multitasking, a generally more sophisticated hard disk based operating system, a built-in screensaver, an advanced calculator with a paper tape and RPN, support for up to 2 megabytes (MB) of RAM, expansion slots, a numeric keypad, data corruption protection schemes such as block sparing, non-physical file names (with the ability to have multiple documents with the same name), and a larger higher-resolution display. 

It would be many years before many of those features were implemented on the Macintosh platform. Protected memory, for instance, did not arrive until the Mac OS X operating system was released in 2001. The Macintosh featured a faster 68000 processor (7.89 MHz) and sound. The complexity of the Lisa operating system and its programs taxed the 5 MHz Motorola 68000 microprocessor so that consumers said it felt sluggish, particularly when scrolling in documents.

Finally, a new post


Moving has taken over my life, but I managed to get many boxes unpacked over the weekend. I wish I counted how many boxes of books we had...but it was wonderful to uncover old friends. The house is shaping up nicely, and tonight I hope to begin tackling the room of hell, aka the room where I dumped everything I didn't want to deal with yet.

I finished a book over the last few weeks, A Wedding in December by Anita Shreve (13). Shreve is someone I turn to when I need mindless reading. This was much better than I expected. She juxtaposes the wedding of two former classmates who were apart for many years after being high school sweethearts--they are now in their early 40s--with the tale of a young doctor in Halifax during WWI. Both stories were captivating.

Now I'm reading Sister Carrie, which is much better than I expected. It's part of my project of reading both the Radcliffe and Modern Library 100 best fiction lists.

I'm still knitting the denim baby pants from Last-Minute Knitted Gifts. It's good to have an easy project while my life is so chaotic, and they're going to be adorable. Next I hope to make some baby hats for Afghans for Afgans, but my mom is nagging me to knit the teddy bear I promised her last May.

I also found a co-op in the neighborhood and signed up for a share of veggies for next week. Next Saturday, I'm going to explore the organic farmers market before taking a beading class, something I've wanted to try for a long time. I was relieved to find good supplies of organic produce; Sweetie and I have been spoiled by living around the corner from an organic market. I didn't know if they would have anything like it in Houston. It's even better to buy straight from the source.
