Congratulations James! 

When I get some time I will try and get UTX/32 running on it.

> 32/87, and 32/97 computers.  This initial release uses a test version
> of the MPX 1.5F operating system.  Source is provided for all
> processors except assemble, Fortran, and sysgen.  I was unable to
> find source for these programs.  Maybe someone can find it
> somewhere.  Also, I do not have an installation SDT tape for MPX
> 3.X.  Again I am unable to find one.  Any and all help would be
> appreciated in finding these releases.  There are still some power
> plants and simulator applications that still use MPX today.   Maybe
> someone knows one that I could contact for the software.

> A bootable disk and a an installation SDT tape are provided.  Make
> sure you see the manuals on bit savers for the 1.x release of MPX.
> There are still bugs, and some features that do not work 100%, but
> this is a real start and maybe some of the forum people can provide
> some debugging help.  All features seem to work including the
> capability to generate new systems via sysgen.  The Fortran is
> Fort77.  SEL uses excess 64 floating point arithmetic, so there is a
> full set of instructions to manipulate these floating point numbers.

> The taptools directory included in the project allows creating .tap
> files from ‘real’ tapes or extracting files from .tap formatted
> tapes.  Also construction of MPX filemgr save/restore .tap tapes.
> Other utilities convert from MPX file format to/from Linux file
> formats.  Some of these might also be usable in other simulator
> applications. 
> 
> The next release will include C programming support and associated
> runtime libraries.  Also an additional set of cross tools that work
> on Linux and MPX.  And, if I can find MPX 3.x SDT tapes, it will also
> support MPX 3.x.

> Find it here www.github.com/AZBevier/sims.  Look at the SEL32 entry.
