Source code for Apple's legendary Lisa operating system to be released for free in 2018

You'll soon be able to take a huge trip down memory lane when it comes to Apple's computer efforts. The Computer History Museum has announced that the source code for the Lisa, Apple's computer that predated the Mac, has been recovered and is being reviewed by Apple itself...

The announcement was made by Al Kossow, a Software Curator at the Computer History Museum. Kossow says that source code for both the operating system and applications has been recovered. Once that code is finished being reviewed by Apple, the Computer History Museum will make the code available sometime in 2018.

While you've been able to run emulators of the Lisa operating system before, this is notable as it's not just a third-party hack solution, but rather Apple is directly involved and the full code will be available for everyone.

Apple Lisa.

    Something like this using Forth? http://www.greenarraychips.com/ [greenarraychips.com]
    "144 fully fledged computers. Just one chip. This gem is our GA144 multi-computer chip. It is designed to give you options that have never before existed and to place them under your control by writing software. With 144 independent computers, it enables parallel or pipelined programming on an unprecedented scale. Map a data flow diagram or an analog block diagram onto its array of computers for continuous processes without interrupts or context switching. With instruction times as low as 1400 picoseconds and consuming as little as 7 picojoules of energy, each of the 144 computers can do its work with unprecedented speed for a microcontroller and yet at unprecedentedly low energy cost, transitioning between running and suspended states in gate delay times. When suspended, each of the computers uses less than 100 nanowatts."

    I agree that this sort of thing might be a lot of fun to play with. And they could put a lot more CPU cores on these chips with a 14nm process.

    My masters' thesis demonstrated a dataflow programming system for an array of parallel DSPs, I think my simulated system had 16 DSPs on a single shared communication bus, with a 68000 control processor; this was in 1989, the PS3 Cell processor ended up launching with a very similar architecture.

    I used digital circuit design/simulation software for the inputs, draw the program on-screen, then the circuit description language got translated to modules to distribute to the parallel machine, optimize the communication bus and processor utilization, etc. It ended up looking a lot like LabView which was, remarkably, a thing already back then - though I didn't discover LabView until I was almost done with the thesis. Research was less efficient in 1989.
