>The Motorola 68020, on the other hand, came out in 1984 and can run fully modern OSes now, in 2024, forty years later. I'd place the cutting point at 68010, which solves a virtualization flaw in 68000 (unprivileged move from SR) and can support virtual memory (can recover from bus error).

There is actually a modern OS (NetBSD) that can run on m68010 systems: https://wiki.netbsd.org/ports/sun2/ https://wiki.netbsd.org/ports/sun2/ However, it'd be difficult to argue that it's actually all that useful ;) On the other hand, an '020 or '030 system can be quite useful. I compile and run lots of software, including sendmail with TLS, on a Mac LC III+ with a 33 MHz '030 and 36 megs of memory.

  >There is actually a modern OS (NetBSD) that can run on m68010 systems: More than one ;) Check out the rosco-m68k (I built one of these), which is actually 68010 based. A few systems have been ported to run on it. IIRC fuzix was one of them. Netbsd can run on 68010, but unfortunately not mmuless.
