I get happy when I see SketchPad on here. I consider it the hands-down best software system that ever existed. If anyone has any ideas as to where/how I might be able to track down the actual SketchPad code I would love to hear it. The https://en.wikipedia.org/wiki/TX-2 https://en.wikipedia.org/wiki/TX-2, the machine SketchPad ran on, had 460KB of 36-bit memory, and it. ran. at. 400kHz. - yes, 400k instructions per second. The CAD system that introduced the idea of the GUI, clipboard, OOP, and so many other things, ran only a little faster than the masked-ROM calculators you can buy for a couple dollars at the store down the road nowadays. It's kind of mind-blowingly awe-inspiring and yet unbelievably depressing. I took the above from what I said last time SketchPad was mentioned (https://news.ycombinator.com/item?id=13938330 https://news.ycombinator.com/item?id=13938330).
