m68k chat 21st Aug 2020 - "the Amitari - EmuTOS and Atari Software on the Amiga"

[Carsten Strotmann]

Hi,

the upcoming m68k developers evening chat is on

Friday 21st August 2020, 20:00 H CEST (6:00 PM UTC)

Location <https://meet.m68k.info/m68k> (will be online 30 minutes 
before
the chat starts)

We will have a short demo: "the Amitari - EmuTOS and Atari 
Software on
the Amiga" and discuss the experiences of running Atari software 
on the
Amiga (might the reverse be possible too --> running AmigaOS 
command
line binaries on TOS?)

The schedule for the m68k chats can be found at 
<https://m68k.info>

CU

Carsten

Sounds awesome. Thanks for organizing this. Looking forward.

Why not?

There did exist a small AmigaOS emulator for Amiga UNIX, basically
implementing a hunk loader and a few exec.library and dos.library calls.
This was rumored to be sufficient to run e.g. the SAS C compiler.
I tried it once on Linux/m68k, and it could run a simple Hello World.

The only entrypoint you need to provide to run AmigaOS binaries is a
pointer to ExecBase at address 4.  If TOS doesn't use that location for
something else, you can implement AmigaOS support.

Good luck! ;-)

There's also vamos, which even sports a 68k emulator (it has Musashi
built in), so you can run SAS/C and similar command line Amiga software on
non-68k hardware.

It's in this repo, mixed up with a bunch of other interesting tools, like
an RDB disk image creator, etc:

https://github.com/cnvogelg/amitools

If I get it right it's somehow written in Python, which sounds scary, but
I've seen it in action and it looked like it's working. Never tried it
myself tho', but I tried other software from the same repo, and they
worked nicely.

Is it possible to run EmuTOS as an AmigaOS "task" already? I know it can
run standalone on various Amiga (and Amiga-related) hardware, but the real
fun - for me anyway - would be to run it alongside AmigaOS. Maybe in a
lightweight VM, like Shapeshifter for MacOS, but course EmuTOS could even
provide such infrastructure for itself. I once even looked at the EmuTOS
code to figure this out, but I never went anywhere with it, because I
realized all the EmuTOS drivers are basically banging the Amiga HW, and
ignore the entire Kickstart.. (Which is understandable from EmuTOS PoV,
but if I want to run it on top of AmigaOS, it means all drivers/etc needs
to be rewritten, which was a much bigger project than I was willing to
take on at that point. Also FIXME, if I was wrong on this.)

I think the main challenge would be sharing the lower 4/8K of RAM, mainly
for TRAP vectors, but exactly for things like Shapeshifter, there's
already a way to handle that. But of course I don't know about various
other Atari-related complications, handling of ST vs. TT RAM, etc.

Overall, I don't know. Just brainstorming. Opinions? :)

I will be a bit late today as I‘m not home yet.
