Peter, Marcel,
I have yet to discover a program that doesn't run on SMSQ/E, provided it's set
to mimic a QL memory map, and does on Minerva (but I'm open to suggestions).
Weird programs are normally sooo weird that they won't run on either...
Minerva is a miraculous thing in terms of code density and still a masterpiece.
It's also, especially when things are getting close to the hardware, much
better documented/commented (sorry, Marcel) than SMSQ/E. Whenever I try to
understand something in terms of original QL HW, my first reference are the
Minerva sources. But:
# of active code maintainers for Minerva: 0
# of active code maintainers for SMSQ/E: some :)
Writing software/drivers for Minerva - just like original QDOS - is also always
a bit of a choice: You /can/ assume, for example (for whatever reasons), that
you want the Thing extension to be loaded. You /can/ also assume, for example,
the Extended Environment - All of this is available for Minerva, and even QDOS.
But that means you build dependencies into the driver/software - On SMSQ/E, all
of this can be taken as a given.
Minerva is also closely tailored to the original QL hardware, for example assuming a
"compatible" memory map (at least in the lower 1M). Changes to that, like
reserving specific areas for specific purposes, I'd assume to be nearly impossible.
(hypothetical examples would be introducing DMA- and non-DMA capable areas, or the
Atari's protected I/O ranges)
If the memory's there: I don't see any good reasons to port Minerva to new
hardware. SMSQ/E is much better suited for both past and future.

Wow, 32 ms is a fast reaction from human ;-)
I guess you can already press the key while the ROMs are still being
scanned :)
As for Minerva in general, would you (or anyone else) see partial
advantages over SMSQ/E on the Q68 that make it worthwhile?
Minerva is a great ROM, it's so amazing what he managed to put into
48KB and anybody not using it on an original QL is certifiable crazy
in my eyes ;-)
But SMSQ/E is still the better OS. It's also much bigger of course,
but also still maintained and with new hardware it's the only way to
go IMHO.

Hi,
Minerva is excellent for an expanded QL, but SMSQ/E is far better.
If the machine can run SMSQ/E thne I would use that by default, but
anything else I use Minerva.
I never understand why people use JS, JM, AH roms.
The argument is that some software does not run on Minerva... Answer:
must be badly written.
