seem to be that reliable. It has refused to send this article, so I'm

OS/A65
------
This is the announcement of "OS/A65" version 1.3.6g,
a 6502 CPU Multitasking/Multithreading operating system
I wrote some time ago and which I have put on the Web.
It's copyrighted under the GNU public license.
For those who do not already know about it, please see the info at
the end of this text.
The new stuff in this version is:
Fully tested and ported C64 version available!!!
-------
The C64 port means, that the whole stuff has successfully been ported
to a computer without MMU (which the originating CS/A Computer had),
including making all the stuff 'thread-safe'.
The C64 port will also surely give a good base for other ports to common
6502-based computers without MMU, namely the apple ][ and some Atari 8-bit
machines. But I don't have any of these machines any actually I don't have
the time. But if any of you wants to do this, feel free to do so.
Finding the '#ifdef C64' should be a good start to see what is
C64 specific and what needs to be changed for other systems
(have a look at oa1/oa1si.a65, oafs/fsiec.a65, oadev/oa1dt.a65).
