LisaGUI is a trustworthy reconstruction of the desktop and consumer interface of Apple’s Lisa, the workstation that fed concepts into the early Macintosh, and it reveals that there are nonetheless issues to study from that system.
A challenge by developer and artist Andrew Yaros, LisaGUI is a replica of the LisaOS in JavaScript. Because the challenge’s information page describes, it is not an emulator. That is partly as a result of such issues exist already, and the source code of its software is available, but it surely’s additionally partly to make it work a bit of higher inside a browser window than a precise emulation of a 42-year-old pc.
It got here to the eye of The Reg FOSS desk as a result of Yaros simply posted a weblog put up about The Why of Lisa G. U. I.. To be trustworthy, the weblog’s intelligent recreation of a basic MS-DOS period textual content consumer interface would possibly nicely have charmed us sufficient to maintain studying, even when we hadn’t been impressed with the recreation – however each actually struck us.
Because the weblog put up explains, there are already web-based recreations of extra mainstream OSes, reminiscent of Windows 93, and the superb Infinite Mac, whose ancestor MacOS9.app we described again in 2022. The Lisa, although, is way much less well-known. The Reg celebrated the machine’s 30th birthday a dozen years in the past, and that article mentions Apple’s 1985 try and relaunch the Lisa 2 because the Macintosh XL. That article has a great few screenshots, and it goes some strategy to illustrate simply how completely different the LisaOS was from the experimental Xerox PARC machines Apple paid to see in 1979.

The factor is, although, that almost all of us – even retrocomputing fans like this vulture – have by no means received to sit down down and work with one for some time. The Lisa was so commercially unsuccessful that, as The Register recounted six years ago, Apple consigned a number of 1000’s of them to a landfill in 1989. Consequently, to get a bit of little bit of a really feel for the way the Lisa labored, it is advisable to mess around with it: create some paperwork, edit some textual content and so forth. That is the place LisaGUI is available in.
The letters “OS” within the title “LisaOS”, by the way, do not stand for “working system.” It was the Lisa Workplace System; the pc got here with a set of what at this time we might name “functions.” The factor is that they don’t seem to be precisely applications that you simply run, as a result of the Lisa did not work like that – which is precisely the type of info which you can’t readily extract from taking a look at static screenshots.
While you double-click on a Lisa Workplace part, it does not open a program, as a result of LisaOS tried to blur away the excellence between applications and paperwork. What appear like app icons are little stacks of stationery templates and double-clicking one creates a brand new piece of that form of stationery. You drag it someplace to retailer it, after which you possibly can work on it. This additionally, nearly as a byproduct, means no “save” and “load” dialog bins. These are instructions for interacting with a program, and that is not how the Lisa was supposed to work: the essential issues had been paperwork, not the instruments that created them.
What paid for the R&D that went into the Lisa was the success of the Apple II vary, which whereas a pioneering eight-bit micro, caught nearer to the conventions set by the minicomputers that got here earlier than it. To set it up, you inserted playing cards into slots, after which Apple II customers needed to study all types of ideas like what applications had been and that you simply needed to load them into reminiscence after which, later, save information information from these applications onto media (cassette tapes or, for the rich, floppy diskettes). The identical type of ideas lay behind CP/M after which in flip MS-DOS.
The Lisa tried to put off such Nineteen Seventies stuff. LisaOS did have multitasking, however then, it did not precisely have applications as such. It was an try at one thing much more bold, as befitted the demo that the Apple techies noticed – and for which Apple paid, in inventory – of Xerox PARC’s prototype Smalltalk system.
After all, the snag was that, when it was launched, the Lisa price $32,500 in at this time’s cash (slightly below £25,000), and it flopped. That is why Apple’s overlapping challenge for a extra inexpensive machine – the Macintosh – drew on a whole lot of Lisa know-how, and on the late Bill Atkinson‘s virtuoso code, but it surely disbursed with lots of the high-concept concepts. It had no onerous disk, not a lot RAM, no multitasking, and it embraced easy, acquainted ideas reminiscent of operating applications from diskettes and saving paperwork – together with standardized load and save dialog bins, as a result of there wasn’t sufficient reminiscence to run the Finder on the similar time and have it deal with that stuff.
As we tried to explain for its 40th anniversary, the Mac was in some methods a extra standard pc than the adventurous and experimental Lisa. That, in flip, meant that for the Mac, the builders needed to invent new metaphors for find out how to do issues fairly than typing instructions at prompts – reminiscent of dialog bins, which allow you to navigate to a folder on a disk.
The Mac was a radical machine in its time – but it surely wasn’t as radical because the Lisa, simply because the Lisa was nowhere close to as radical as Smalltalk on a Xerox Alto. However then, as Steve Jobs freely admitted in later interviews, he missed a lot of the importance of Xerox’s demos – he was so spellbound by the graphical consumer interface, he did not register the networking, or the programming language, or its object-oriented simplicity.
Lots of the concepts and designs and implementations that had been new within the authentic Macintosh in 1984 are in all places now: they’re so ubiquitous, we do not discover them. These embody dialog bins, maximize and decrease buttons in title bars, and a transparent distinction between this system you are utilizing proper now and the underlying OS. That stuff wasn’t there on the Lisa – both as a result of it wasn’t wanted, or as a result of it simply hadn’t been invented but.
It isn’t so seen in screenshots, and it is advisable to be eager to emulate a pc you have by no means even seen. LisaGUI implies that you needn’t: it is proper there, in seconds. Have a mess around. It is enjoyable. ®
