No, it doesn't have memory management, so not any of the well-known 'stock'
versions (V5/V6/etc).
Two choices, though:
- If you get the V1 that ran on an -11/20 (which is mostly compatible with
the /04 and /05), it should run on an /04. (Not sure what you'd use for mass
storage, on a physical /04, though.) I'm not sure when they dropped the /20 -
I think V4 n(at the latest)? But V2 and V3 are lost.
- There's a 'Unix' for the LSI-11, and with minor changes (the LSI-11 isn't
100% compatible with other MMU-less 11's, but the changes are minor, e.g.
MOS, written in MACRO-11, was conditionalized to run on both the LSI-11
and the -11/20) it should run on an /04.
