So here is a write up about another interesting Twiggy disc. It includes many early demos that are also mentioned in Andy's book and his web page Folklore.org.

The disc boots into Finder 2.0 (25-jul-82).

I think the most interesting early demo was an early prototype for the Finder, written by Bruce Horn and myself in the spring of 1982, and pictured above. Its window was filled with an image of a floppy disc, over which the files were represented as draggable tabs. You could select files and perform operations on them by selecting them and then clicking on command button.

The first demo app I have tried was named SBARDEMO shows a window with Bob Dylan's song. Thats all al what can you do here is drag and scroll the window.

The second app was called SoundLab.

The next day, we decided to write a demo called "SoundLab" that would let the user control the pitch and waveform of the four independent voices. You could specify or edit a waveform by drawing it with the mouse, and control the frequency of each voice with a scrollbar. The results didn't sound like music, because there was no envelope shaping, but you could make very eerie sounding noises, which we deemed impressive enough. And it was fun to be able to hook an oscilloscope up to the sound output, and then draw a waveform with the mouse and see it on the scope.

The third one was by now well know Bouncing Pepsi Caps app

The next week, Mike Murray led John Sculley around the engineering area, since Steve was out of town. He brought him by my cubicle to see the modified Window Manager demo. I opened the windows one at a time, saving the Pepsi caps and cans for last. He seemed genuinely excited to see the Pepsi stuff, but oddly cold for most of the demo. He asked a few questions, but he didn't seem all that interested in the answers.

Fourth, the IconEditor. There are no icons saved on disc so I had to draw mine.

In February 1983, I worked on putting together an icon editor for Susan Kare to use to create icons for the Finder. Inspired by the "Fat Bits" pixel editing mode that Bill Atkinson had recently added to MacPaint, it had a large window with a 32 by 32 grid, displaying each pixel at eight times its natural size, as well as a small window that showed the icon at its actual size. Clicking on a pixel would invert it, and subsequent dragging would propagate the change to the dragged over pixels.

And the last was MacPaint version 0.1. About MacPaint/MacSketch I will do another write up in another post.

Around April 1983, Bill changed the name of the program from MacSketch to MacPaint. He began to hit his stride, and started to add new features to MacPaint on a daily basis. One of the most important was "Fat Bits", a mode which magnified a small section of the document by a factor of 8, allowing the user to easily manipulate individual pixels. It was implemented by scaling the offscreen buffer as it was transferred to the screen, so all of the other tools and effects kept working in Fat Bits mode.

The discs also had its own BootScreen MacTime. Could be it put some pressure on developers as the release date was really close :)

By the fall of 1983, we had committed to announcing and shipping the Macintosh at Apple's next annual shareholder's meeting, to be held on January 24th, 1984. The failure of the Twiggy disk drive almost caused us to be late (see Quick, Hide In This Closet!), but it seemed like the new Sony 3.5 inch drive solved all of our problems, and the rest of the hardware was ready to go. The Macintosh ROM was frozen in early September and sent out for fabrication. All that remained was finishing the System Disk, and our two applications, MacWrite and MacPaint.

I have also post a video on youtube. I tried all this software on a real 128k Mac. The discs image was converted from Twiggy disc to 128k Mac by Matey Hybler who also made Mini vMac Twiggy emolutaion possible. The MacPaint sadly does not work on 128k Mac.

Pretty cool to see all the stuff used to make the Mac!

I've read about them before, but to get such nice quality screenshots is great. Have these apps been out in the wild before, or is this the first chance we have to put the apps themselves on the web somewhere?

Thanks. This is not available for public yet. I hope someone will continue to work on Mac Twiggy emulation where Matej Hybler left. I havent heard from him for 10 years now … but thats for another post
