MOSYS — another Modula-2 OS

I was part of the development team at RSE lead by Brian Kirk that developed MOSYS for Motorola 68000 based workstations in the UK — we licensed the base Modula-2 compiler for Lilith from ETH. MOSYS was completely separate from Medos-2. It saw limited usage in the UK and was not a commercial success. The work was partially re-used for 68000 based embedded systems.
I later moved to GEC Avionics where among other things I helped port the BCPC compiler to GEC4000 machines, which has an OS written in Coral-66 (also influenced by ALGOL) and Assembly Code. The Coral-66 compiler was written in BCPL which is why it needed porting to GEC4000 (from the VAX).
