As a matter of fact, the Mini-frame was, at one point,
not much more than an overweight UNIX(rg)-pc: sort of
the price one paid for a coupla extra connectors. If
you are NOT running SVR3, this is probably the most
appropriate hole in which to post questions!
Yes, a bit of history -- as distorted by my weak
recollections -- of things:
The 3B1 & Mini-frame software had the same --
or very common -- base, many years ago. As I recall,
there were numerous 'ifdefs'. For various contractual
reasons -- proprietary issues, mostly -- CT's product-
line kernel staff were separated from the AT&T-product
kernel staff and an unknown [to me] amount of divergence
ensued.

^^^^^^^^^^^^^^^^^^
Since I haven't the faintest idea of what "v3.10net" is,
I can't address it directly. The UNIX-pc is derived from
CTIX: the UNIX-pc was NOT BASED on SVR3 -- although much
of the SVID [System V Interface Definition] is common.

It is quite possible that CTIX remains binary-compatible with
the UNIX-pc. Divergence [from Convergence ?-) ] in the Shared
library is always a threat. Or, subtle variations in the
system calls could have crept in:
AT&T spent considerable effort maximizing SVID
compliance for the UNIX-pc. CT may not have incorporated
those in their product. Conversely: they may be MORE in
compliance by virtue of running a full SVR3. (If you
have /usr/include/sys/region.h you're SVR3.)
AT&T did attempt to contract with CT to deploy the CT SVR3
"product" (I never really saw it, and don't know if was
ever really released for the Mini-frame) on the 3B1, but
negotiations (or work) collapsed as strains accumulated
-- typical when a LARGE and small corporation work together.
[No comment.]
Toward the end of our period of depending on CT to
do the 3B1 kernel work, we were told, a number of times,
"we've already fixed that in our version" -- indicating
they had isolated AT&T contract work from their own BUG
FIXES! (Save electrons: you can't add anything meaningful
to OUR comments.) This may indicate further divergences,
even if you aren't running SVR3.
While you CAN avoid shared libraries, they are generally a REAL
blessing in disk/swap savings.

Has anyone seen a P[ublic] D[omain] korn shell for anything?

'Think there was always a nominal fee: in the early days
it was little more than a tape-charge.
Try phoning: (800) 828-UNIX -- and post your results.

Try loading a STRIPped 'gcc' from someone's UNIX-pc. If it
can run, can't you bootstrap to a full, long-names ["flexnames"]
development environment? (The UNIX-pc moved to "flexnames"
around release 3.0 [or was that 3.5?].)
