Most, if not all, m88k-based systems were originally delivered with some kind of UNIX derivate.
These derivates in turn mostly were based on Motorola's port of System V UNIX to the m88k architecture (SysV/88k).
As of late 2003, the only freely available open-source OSs are the OpenBSD/mvme88k
and OpenBSD/luna88k ports.
Efforts to port Linux to m88k-based systems never got over the planning stage.
A NetBSD port also was projected over the times but did not produce much visible output.
- Motorola System V/88 Unix R3.2 V3
The first version of Motorola's own port of System V Unix to run on its m88k-based System, only
supports 88100-based configurations though.
- Motorola System V/88 Unix R4.0 V3
The next major release of Motorola Unix, now supporting the newer 88110-based computers and a much
more advanced userland.
The original OpenBSD port to the m88k-platform, at the beginning only supporting
The state of the port fluctuated a lot over the years but reached a stable state as of OpenBSD 3.6.
A newer port to the relatively unknown and rare Omron m88k-based Luna computers, based on OpenBSD/mvme88k
and NetBSD/luna68k sources.
