unix query

[utzoo!decvax!ucbvax!mhtsa!eagle!ihnss!houxi!houxb!larryg]

Does anyone know of a form of unix that runs on lsi-11's (ie the
pdp-11/02 or pdp-11/03) with AED floppies and is available outside
the bell system.
I have heard of something called LSX but have been told that this
is not available outside the bell system.

I have also heard of something called mini unix which is a small
(12K) version of unix, but as of yet have not found anyone who
has it running on lsi-11's.

Any serious replies (ie something other than "why dont you get
a more powerfull pdp-11") should be sent to ...!mhtsa!pyuxu!mja
(where ... is whatever path you need to use to get to mhtsa),
NOT to the place from this was message was sent.

Note that this software is needed to be used at a school for
(non-comercial) research use.
