This is fantastic! I love the CLARIS-inspired "box" art too https://i.imgur.com/P9G7jOx.jpg https://i.imgur.com/P9G7jOx.jpg

Came here for this exact comment. The artwork is spot on. That, by itself alone, would have been amazing. I don't miss the lack of memory protection of classic Mac OS, but I do miss everything else.

  Didn't last Mac OS 9 versions have memory protection? I mean there's a reason it's hard to run 9.2 on an emulator — it requires a working MMU.
  - tambourine_man 5y ago
    No, after 8.6 the system featured a micro kernel on which the old OS ran atop. I think you could opt in for better stability, but I'm not sure. But most of the OS and apps still ran on the same shared memory space with cooperative multitasking, meaning a single app could (and did) bring the whole system down. I think you can emulate 9.2 just fine, but it's been a while since I played with this things.

    Mac OS 9 has virtual memory (it uses virtual address translation and it can swap pages to disk), but it still has a single address space that is shared between every application.

      Ah. I remember reading "it has virtual memory" and assumed that this includes each process running in its own address space. Was it common for applications to reach directly into kernel memory instead of using proper APIs?

    It has preemptive multitasking for compute-only tasks (the MultiProcessing library. See http://mirror.informatimago.com/next/developer.apple.com/technotes/tn/tn1176.html#mpapi http://mirror.informatimago.com/next/developer.apple.com/tec...) I also think the OS, technically, was preemptive multitasking, but ran all ‘normal’ code in a single preemptive task (https://groups.google.com/g/comp.sys.mac.programmer.help/c/fqdq59fxQ1g/m/uSy4DSDLeJcJ https://groups.google.com/g/comp.sys.mac.programmer.help/c/f...) I also vaguely remember the kernel had some memory protection enabled. Of course, almost none of that mattered for typical user-space programs.

    This is an issue for SheepShaver (limited to 9.0.4 because 9.1 and up require the MMU as you say), but not QEMU, which emulates the MMU and thus runs 9.2 just fine.

I genuinely think it fits right in. Apple always had a good aesthetic, even when everything was beige and rectangular. I did a giant chunk of my school work on Claris Works, before I discovered latex. Happy memories.

  If only I could still get laptops with the keys printed in Univers 57 Condensed Oblique :) https://catalog.monotype.com/font/linotype/univers/57-condensed-oblique https://catalog.monotype.com/font/linotype/univers/57-conden...

    well you can on ebay ;)

  That aesthetic was widespread throughout the PC universe in the 90s as well. I remember having a giant clip-art library that came on a whole bunch of CDs, and actually came with a catalog book to leaf through. A lot of it looked like that. Another example is Microsoft's clipart library, (in)famous for its images of the "screen bean" guy.

thanks, I had fun making it! there's full design for a box and a floppy label that I've made for the upcoming 1.0 release
- fzzzy 5y ago
  Are you going to do an actual release on floppy? You should. I will buy it.
  - cy384 5y ago
    yes, I think I'm going to make a dozen or so copies, just to make it feel real
