Nice find. What does the label on the big hard drive read= ? I have found a similar drive with a worn label and i am trying to see if = i can find a system to connect it to.

Ah, I just read this carefully; LSX only supports a single user at a time, = so
there's no use to multiple serial lines? (But see below.) (I thought He= inz'
reply message to this referred to Mini-Unix, which does suppport multiple users, but on reading it again I see it does not.)


If you want multiple users on an -11/03, Mini-Unix would be an option; it doesn't support the -11/03 'out of the box', but looking at it,= it shouldn't
be too hard. (Heinz mentioned that it had been done before.) Change all cas= es
of 'mov xx, PS' in mch.s:

=C2=A0 https://minnie.tuhs.org//cgi-bin/utree.pl?file=3DMini-Unix/usr/sys/m= xsys/mch.s

to 'MTPS xx' (PS access needs a special instructtion in the /03); t= hat might
be all you need to do. (Installing a KEV11-A, so you can avoid using the instruction emulation package for EIS instructions would be nice, but
apparently isn't required.)


If Mini-Unix supports multiple users, it ought to be possible to do the sam= e
with LSX. (I'm not sure what the rationale was for making LSX single-us= er:
perhaps the RX was too slow; perhaps there was no need in their use case; etc.)

But it would probably be more work than going the Mini-Unix route; e.g.
to start with, init only supports a single user:

=C2=A0 https://= minnie.tuhs.org//cgi-bin/utree.pl?file=3DLSX/src/init.c

and the tty driver:

=C2=A0 https://mi= nnie.tuhs.org//cgi-bin/utree.pl?file=3DLSX/sys/tv.c

only supports a single line. One could cross-port the needed 'stuff'= ; from
Mini-Unix, but it'd probably be easier to do the Mini-Unix -11/03 conve= rsion.
