Finally ! The simulation problem has been circumvented. It doesn't work in simulation yet, but at least it's possible to simulate.

Got a small program to display random characters on the screen running. With three cpu's running the display is updated three times as often as a single cpu could do. (The system has six cpu's) but only three are being used for the display. It doesn't work perfectly yet, a couple of chars on the screen are "stuck" at fixed values. Probably a random number generator problem.

We mentioned ZMOB earlier, a scalable highly parallel Z80 based architecture. It turns out it was also built - maybe in 1988 - with 68k CPUs, dubbed McMOB:
http://www.dtic.mil/docs/citations/ADA196942
"... a parallel problem solving system, PRISM (Parallel Inference System), that was implemented on the VAX/11-780, the PYRAMID and SUN machines, was ported successfully to McMOB and then to the BBN Butterfly parallel architecture. The McMOB architecture is essentially the ZMOB architecture with 16 Motorola 68000 processors, upgrading the Z80A microprocessors, interconnected in a ring structure. Experimental testing of PRISM on McMOB was undertaken in the current year."
