An earlier thread here suggests CP/A was renamed OS/A+ following legal issues with the name from the owners of CP/M.
According to manual dates it looks like it was written first on the Apple 2 and ported to the Atari.
CP/Apple Feb 1980 V1.0
CP/A (Atari) March 1981 V1.0
OS/A+ Atari May 1981 V1,1
I had a quick look and the closest was https://archive.org/details/oss-basic-manual/CP-A License and Notes/
This is a OSS CP/A for Apple 2 - an earlier version of OS/A+ also available on Atari (?).
The notes there suggest that OS/A+ apple may not have been released (although I know the Atari manual has references to it).
I booted the Apple 2 woz image under emulation and it looks very much like a minimal OS/A+ and it has OSS BASIC 1.0 on the disk.
I had an Atari 1027 printer back in the day, and it quickly broke. In fact, I recall probably only successfully printing a handful of pages, something which was very annoying and apparently common.
I remember the letters were slightly offset from each other and didn't quite line up. It also made a terrible noise when printing. Were these faults or usual behaviour?
Is there any sort of emulation? Maybe a true type fonts of the pseudo-daisy wheel character set? Or a way of printing them to a PDF under emulation or real hardware?
Unfortunately, the compiler doesn't work when I tried it under SDX 4.48 cartridge (old I know!)
Also, when compiled, it needs to run from the % prompt by just typing "HI".
(Note, you need the LIB file if trying this on another disk.)
Since the death of Wirth I've been playing with Kyan Pascal (which is a lot better than I expected!).
I've been trying to use it on a double density disk but the only DOS which seems to work for it is TurboDOS-XE.
Does anyone know of English language docs for this DOS? Or can recommend another DOS for use with KP?
Another from scratch approach would be to take the source for a simple hash (aka associative array or map) and port to another language.
I once took, and the source is long lost but it wasn't hard, a short C simple example (off google) of an associative array and ported it to CC65 quite easily.

In the movie True Stories (1986) starring David Byrne and John Goodman, the scene at the mall shows the computer programmer (played by Matthew Posey) having purchased an arm-full of Atari 8 bit products.
Looks like it was a 1010!
It's a (moderately well known) arty Americana film of the 80s set in Texas.
I certainly wouldn't expect everyone to have heard of it, but I'd guess a few have and might even have an old DVD around somewhere.

I was watching David Byrne's True Stories and noticed for the first time that a guy in the 80s mall he was talking to was carrying Atari 8 bit boxes.
Looks like an APX box and a 1050 drive box? Does anyone else spot anything?
