Colin,

Sorry you didn't make it - maybe you can make the next one.

Your question:  Can you take a disk out of a System IV and stick it in a MM/1
(and have it work)?

First to qualify my answers - I can speak authoritively for the SYSTEM IV. I
don't have an MM/1 so my statements about it are based on my understanding of
that machine.  Also, I have to divide your answer into three parts - plain
'text' type programs, programs that use graphics and disk formats.

Programs not using graphics -

In this sense, the SYSTEM IV is a 'vanilla' machine.  It uses a standard 68000.
Programs, whether compiled on the SYSTEM IV or other machines (the Hazelwood
boards used in FHL's QT series, Motorola and Mizar boards used in VME systems,
etc.), all worked on each of the other machines.  Exception - some programs
compiled on the Atari ST under OS9 have not worked on any of the above
machines.  We _think_ these programs use a feature of the ST that the other
machines don't have.  Not having the source files for these programs I can't
say what the problem is.  (No, we haven't dissassembled the code.)
