Two possible meanings; a system image for a Mini-Unix system (buildable under
V6 with the standard V6 tool-chain of C-compiler/assembler/linker), and user
command binaries (buildable with the C-compiler/assembler, but needing a
special Mini-Unix linker - written in C, and compilable/runnable under V6).
I've done both in my recent Mini-Unix work.
(For those are are not familiar with Mini-Unix and LSX, they are both V6 Unix
variants lobotomized to run on PDP-11's without memory management: -11/05's,
etc. I'm currently working on getting Mini-Unix to run on an -11/03; not a
major change, but not a model supported 'out of the box'. LSX is more heavily
cut down, so it will run on even smaller systems - I seem to recollect 20KB
or so - but that's not that useful nowadays, with semi-conductor memory being
