The all in one web editor for M68K (specy.app)

I assumed it's an editor for Web that can run on m68k


Yeah, me too. But no--it's an editor for m68k assembly, said editor runs in your browser.


Very cool and well done.. is this retarget-able to the 6502 ?


Not very well versed in 68k, but why doesn't it recognise the LEA instruction?


I'm gonna add it those days


Added!


It doesn't seem to like "clr.l (a6)+" for some reason.


moveq also not supported: http://68k.hax.com/MOVEQ

Good idea, however this is very disappointing. On Amiga, I used moveq extremely often to clear stuff.


Hey, I'm the developer, I noticed some activity on GitHub so I wanted to find out where it was coming from, the interpreter itself is for learning, I haven't added the quick instructions as they weren't really useful speed wise, but I'll add them anyway just for allowing the syntax, if anyone finds issues, let me know on GitHub, the app is still in beta


> I haven't added the quick instructions as they weren't really useful speed wise

they are THE FASTEST way to clear a full 32 bit reg, for example, by far.


Yes I mean in the context of the interpreter, in the end both quick and not quick instructions end up running the same code in the interpreter, but I'll add it anyway


SUBQ also seems to be missing.

Interesting project and it may be a useful tool for learning M68K assembler for a beginner, but as an editor or simulator it seems very limited at the moment. Always nice to see some new M68K tools though


Can G4 macs run OS 9?


The G4s were the period during which Apple transitioned from Classic MacOS to Mac OS X.

Early G4s all could boot Classic. The last few couldn't. No G5s can.

(Note: all PowerMacs that can run Mac OS X 10.0-10.4 can run Classic inside the integrated "Blue Box" VM.)

The Mirrored Drive Door PowerMac G4 models that come with Firewire 800 can't boot Classic natively. Others after that, such as the Mac mini G4, and iBook G4, can't either.

Apple disabled Classic from booting by modifying the later machines' firmware.

A community of hackers has been finding ways around this, and now for some models there are special editions of Classic MacOS 9.2.2 that later G4 machines can run, which they couldn't at launch.

G4 MDD version:

Versions for iBook G4, Mac mini G4, and PowerBook G4:

Yes, most if not all came with Mac OS 9 pre-installed.

[EDIT] I just re-checked - up to and including the "Mirrored Drive Doors" models, all PowerMac G4 models could boot into Mac OS 9.
