#Presentacion
Yo he venido aquí a hablar sobre la informática de verdad, retroinformática que la llaman ahora ;-) Para aprender y hablar sobre mis inquietudes con los ordenadores de 8 bits (principalmente MSX), de 16 bits y 32 bits (principalmente Commodore Amiga) pero también de sistemas DOS, Win9x/XP, UNIX,...
Si te interesan estos temas dame un toque.

Asm Editor is a web app IDE for learning, developing, and running x86, M68K, RISC-V, and MIPS Assembly code. It features an editor, assembler, and debugger, as well as other tools and learning resources.
Doing 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....
Now you can witness one of the first quickdraw calls from MicroPython on mac... 
I'm testing a freshly assembled #PiStorm on a real Amiga 500.
I have no prior experience with the PiStorm, so I followed the README to install the system image onto a RaspberryPi 3, compile the emulator from git head and... run it!
The #Amiga started right away and loaded my SysInfo disk image. However, there are text rendering glitches, and the m68k emulator runs even slower than the original hardware running at 7 MHz 
asyncio is working on mac micropython!
also (not shown here) the "sys.stdin" object is pollable, and you can double-click a python file to run it as the main code file.
Are 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. (I do have Inside Macintosh but it is not a great tutorial)
oh 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.
Whee! 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).
yay, successfully wrote & read back file contents with micropython on macos 6. #micropython #retrocomputing #retro68 #macintosh #m68k
EmuTOS 1.4.0 release is out. I uploaded the ROM images to my Sidecartridge TOS emulator in my Atari STE. It works fine, nothing spectacular to report.
The Hungarian ROM also works, too bad some capital letters with accents look shifted. I will stick to the English one, I guess.
BTW, since the last round of fixes, my STE is rock solid & stable. Finally. It took like 6 years, but I got this thing to behave. 
Fingers crossed it'll stay that way for a while.
#NetBSD #m68k now has binary packages for clang and llvm.

Does anyone want to give them a try?
Some think about lighting a terrible fire, and then some prefer igniting an entire inferno. 
I wonder how much of an advantage it was for #Apple that the #m68k #Macintosh had a bunch of its operating system in a separate ROM chip.
#Microsoft #Windows didn't have that. The whole thing had to be loaded from disk into RAM.
Windows 1.0 required no less than 256kB of RAM—twice as much as the first #Mac model had.
I got a working toolchain. Now I just need one of the silver USB GraphLink cables to be able to transfer software to it. (if you have one you don't need let me know)
I became the custodian of this Mac IIcx early October last year. It was in the batch that had the Apple IIe in it, among other machines. It sports a Motorola 68030 CPU at 16Mhz and a whopping 4MB of RAM.
The mainboard suffered some corrosion from capacitor leakage, but thanks to friends at berlinCreators e.V., it is now back to life. Everything minus the soft power-off works. But we'll get there, eventually.
It happily boots to MacOS 7.5.5 from a SCSI2SD v5.
Check out my new M68K cyberdeck 
Under the title link you will find a modern web application for writing, executing and learning M68K assembler code, which uses the SvelteKit framework and the Rust programming language. The tool now supports not only 68k, but also MIPS architecture:
