Lisa OS and applications source code now available
stepleton:
Worth noting that the ToolKit documentation talks about being able to switch to the screen with that debug output --- IIRC with the help of an extra menu that pops up for suitably compiled programs or something like that. I remember thinking that the debugging facilities for ToolKit programs sounded considerably more powerful than I'd expected.

--- Quote from: blusnowkitty on January 19, 2023, 05:27:29 pm ---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!

How much faster do you think an optimized Office System 3.2 would end up being just from that alone? There must be other fixes and optimizations just waiting to be discovered here.
kgraaf:
I have two questions:
1. Did the dump include the Pascal Workshop and/or any of the compilers? If not, what are we missing?
2. Do we have enough to do a fresh build of the OS? I would be more than happy to work on an Office System 4 release if anyone's interested in that. (Stuff like Y2K support would be nice, as I recall the Office System doesn't have it)
stepleton:
1. I don't think so, but Al Kossow found some related bits and mentioned them in this thread: https://lisalist2.com/index.php/topic,348.15.html
I haven't looked too closely at what's in some of the shared archives, but I wouldn't be surprised if creature comforts like the Workshop shell and the editor are missing. I'm not sure whether the code generator, linker, or assembler are there either, not to mention various libraries.
2. This is unknown! But I think lots of folks would love to find out if it's possible.
Al Kossow:
There are no Workshop components other than the toolkit 3.0 sources in what was released.
Also, I pushed out the rest of what I have on Lisa 1.75 this morning. It looks like the project was
abandoned when Pepsi started and Twiggies were killed. The Pepsi codename obviously comes from Sculley
who started Apr, 1983
