Lisa OS and applications source code now available

So, based on the license Apple put this under, if we make modifications to the code are we allowed to share them?
The benchmarking line makes me think we can't even talk about using LOS??

Well, check out section 2 where it begins "If you create modifications of the Apple Software,..."

Would be good to have a clarification on this point.

This is especially bittersweet. Had Ray had access to this code would it have helped him with the development of LisaEm? I presume this will at least make software development for the Lisa easier in the future.

It's beyond question: yes, immensely.

We know that the Lisa's underlying OS had a primary screen, where all of the pretty GUI magic happened, and if you installed the Workshop, you'd have a secondary screen where you could dump your debug output. At a cursory glance, it appears as if the secondary screen is in memory at all times whether or not you're debugging a program. More worryingly, it looks like every single piece of code - OS, drivers, LisaDesk/Filer, Lisa applications - just dumps loads of debug WRITELNs (pascal's printf?) to the secondary screen whenever anything happens, and none of it appears to be #ifdef'd out. Maybe that's another reason why the Office System is so slow, every time you click the mouse button it prints a debug statement to the debug screen!
Trying to find an old post of mine now, one time I had something in the OS crash so hard it printed the crash/debug messages to the primary display instead of throwing up a "The Lisa is having technical difficulties" dialog. I want to grep that and see if I can find that in the source anywhere...
