StylusDoing a little iterative code development in micropython on an emulated m68k mac... I might not be so happy with the loading time if a real floppy was involved, but in an emulator it's heckin' snappy.Clearly I need to tackle the issue that you can't REALLY draw to the same window as the terminal....<a href="https://social.afront.org/tags/micropython" class="mention hashtag" rel="nofollow noopener" target="_blank">#micropython</a> <a href="https://social.afront.org/tags/python" class="mention hashtag" rel="nofollow noopener" target="_blank">#python</a> <a href="https://social.afront.org/tags/retroComputing" class="mention hashtag" rel="nofollow noopener" target="_blank">#retroComputing</a> <a href="https://social.afront.org/tags/retro68" class="mention hashtag" rel="nofollow noopener" target="_blank">#retro68</a> <a href="https://social.afront.org/tags/macintosh" class="mention hashtag" rel="nofollow noopener" target="_blank">#macintosh</a> <a href="https://social.afront.org/tags/m68k" class="mention hashtag" rel="nofollow noopener" target="_blank">#m68k</a>

StylusAre there any folks with vintage Mac programming experience who'd like to collaborate on figuring out what's next with Micropython on Mac?I think that might be: What's the minimal set of APIs to do a fun graphical demo.Pointers to "how to"-ish documentation in Pascal and C would be great as well, I have failed at finding this kind of stuff.

Stylusoh my yay, it now works well enough to save and edit a file, then import and run that file.you could basically use an old m68k mac as a python3 (well, micropython) development system now.don't mind the debug messages, they're as scared of you as you are of them.<a href="https://social.afront.org/tags/micropython" class="mention hashtag" rel="nofollow noopener" target="_blank">#micropython</a> <a href="https://social.afront.org/tags/python" class="mention hashtag" rel="nofollow noopener" target="_blank">#python</a> <a href="https://social.afront.org/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener" target="_blank">#retrocomputing</a> <a href="https://social.afront.org/tags/retro68" class="mention hashtag" rel="nofollow noopener" target="_blank">#retro68</a> <a href="https://social.afront.org/tags/macintosh" class="mention hashtag" rel="nofollow noopener" target="_blank">#macintosh</a> <a href="https://social.afront.org/tags/m68k" class="mention hashtag" rel="nofollow noopener" target="_blank">#m68k</a>

StylusWhee! Now we can import files from the filesystem, as well as reading and writing files. Still haven't wrapped my head around how folders work, still can't enumerate files .. as usual, work pushed to my micropython fork on github (which is called circuitpython, because you can't have two different forks of the "same" original project, argh).<a href="https://social.afront.org/tags/micropython" class="mention hashtag" rel="nofollow noopener" target="_blank">#micropython</a> <a href="https://social.afront.org/tags/python" class="mention hashtag" rel="nofollow noopener" target="_blank">#python</a> <a href="https://social.afront.org/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener" target="_blank">#retrocomputing</a> <a href="https://social.afront.org/tags/retro68" class="mention hashtag" rel="nofollow noopener" target="_blank">#retro68</a> <a href="https://social.afront.org/tags/macintosh" class="mention hashtag" rel="nofollow noopener" target="_blank">#macintosh</a> <a href="https://social.afront.org/tags/m68k" class="mention hashtag" rel="nofollow noopener" target="_blank">#m68k</a>

Alanna 🏳️‍🌈🏳️‍⚧️I got uploading to a SRAM working from an Arduino Nano! I have also tested properly resetting the 68008 from the Arduino and changing the pins to pull up. I should probably throw together a tiny bootloader and put a 512K SRAM on instead, and I think perhaps a SPLD or CPLD might replace the mess near the RAM more elegantly - a couple of daisy chained ATF22V10s might work well! It all seems stable at ~6Mhz despite being on a breadboard.<a href="https://mastodon.ie/tags/m68k" class="mention hashtag" rel="nofollow noopener" target="_blank">#m68k</a> <a href="https://mastodon.ie/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener" target="_blank">#retrocomputing</a> <a href="https://mastodon.ie/tags/breadboard" class="mention hashtag" rel="nofollow noopener" target="_blank">#breadboard</a>

Earlier this year I wanted to find out, so I set up a Macintosh to try it.The toolchain, OS and installation sets started on 16-March and finished on 10-May:<pre><code>build.sh started: Sat Mar 16 17:04:20 UTC 2024 <a href="http://build.sh" rel="nofollow noopener" target="_blank">build.sh</a> ended: Fri May 10 00:35:54 UTC 2024 4692724.22 real 3810544.56 user 700310.18 sys</code></pre>That’s 1303 and a half hours, or almost eight weeks, or 54 days.Installing the OS using <a href="http://build.sh" rel="nofollow noopener" target="_blank">build.sh</a> took another four hours (4:08:39).The kernel took another almost 21 hours (20:55).That’s a lot of time, but it worked without issues, and the system runs happily!
