How about UNIX on you Apple II?

Been working on it since 1988, eh? That's a long time. I've actually used LUnix on the C64 - though admittedly that's easier to do since there is better banking in/out of large swathes of memory on that platform (even more so on the C128).

Here is a link to a discussion on csa2, through Google Groups, about XINU, a Unix like operating system for the Apple 2, that David Finnigan was trying to work on and fix for the II. His last post about it was back in 2010.

Just my II cents worth,

LOL! Naw, I think the 6502 version was just started late last year (2014).

Oh, ok. I was keying off of this:

Read 131072 bytes from '6502.rom'
Fuzix.
FUZIX version 0.1

Enabling interrupts ... ok.

Starting /init

But anyway, as Magnus and I point out, it's one of several such projects out there. Very interesting studies in marshaling resources in highly constrained systems, all.

Well not to forget:
in the mid to late 80´s there also was SCO.
Their problem: demanding outragious prices for their licenses....
that in fact got the company also down to the cellar....
if the prices would have been more reasonable they would have had a chance to survive
with more customers and more resourcces for development.....

nowadays it´s a quite interesting task analyzing that early attempt to UNIX IV and V....
but it recommends a harddisk system to start from....

Kyan Pascal came with a Unix-like shell called Kix. It was kind of like a Unix command line interface. The underlying OS was still ProDos. It was how I first learned Unix shell commands back in the 80's.

Wow, that's when I was still a beginner at 6502 assembly language!
