Summary: Atari OS-9 Multitasking confirmed
Xref: lsuc comp.sys.amiga:1751 comp.sys.mac:1037 comp.sys.m68k:205 comp.sys.misc:263


     Last night I was particularly busy and I had an excellent chance to
confirm OS-9 Multitasking on the Atari 1040ST.  I did a mass download with
Kermit from my Unix node with the following command line:

kermit rl /t1 >>>temp &

     The '>>>temp' is a redirection of 'stdout' and 'stderr' to a file.
While that was going on (over a half hour's worth of download at 1200 baud)
I began a formatted printout with the 'pr' utility as follows:

pr -l=5 >/p &

     That printout was something like 20 pages and ran for a fairly long
time in itself.  It was done before the download.

     While doing all that  I edited a couple of files with the Scred full
screen text editor.  I found no apparent degredation, even with cursor
movements and screen redrawing.  Memory left over tended to be around
250K to 350K depending on what I was doing at any given time.  This is
typical (I was using 64K for Hard Disk Cache and 256K RAM disk and had
booted from TOS indirectly leaving all the TOS/GEM memory intact *beside*
OS-9 in RAM).

     I also did some re-arranging of files on the Hard Disk without problems
(ie.  No interference with disk accesses from Kermit's download).

     In fact, it's my impression that if I had a 2nd RS-232 port I could
easily have started another connection to another system for Telecom or
even more crossloading.
