Well another driver is that (decades ago)
I saw someone write "until DOS itself is
made 32-bit, DOS extenders are just a kludge",
and I always wondered when DOS was going to
be made 32-bit. It never happened, but I
think it should have happened, so I made
it happen myself. Proof of concept.

I am not necessarily striving for simplicity.
I have a hard time describing what I am
striving for, it's more a case of "just what
comes naturally". I wish I had a better grasp
of what I want.

I looked up p-system and it seems to be Pascal
and interpreted, but I don't want either of
those things.

Note that PDOS/3X0 already exists, it's not
just an intention.

I block (wait for interrupt) on the mainframe
too. My goal is not to have a perfect system
in version 1.0. My goal is to have it
self-hosting in version 1.0 so that someone
can take a mainframe onto a desert island
and spent the next 50 years making PDOS/3X0
the best multitasking operating system ever.

After I have made it self-hosting I may
stop development and find a new platform,
like ARM, to make self-hosting, so that
an ARM computer can be taken to a different
desert island (or planetary system) to be
worked on.

I'm not that worried about performance.
That can be improved in time, and it is
good enough that it was written in C,
so there is a good base.

Applications written for S/380 will also
run on z/OS and MVS 3.8J. All it does is
provide lots of memory (4 GiB with AMODE
32 in fact) to those using emulation anyway.
