Yes.  Yes.

Yes.  Not at present.

The configuration menu shows 38.4, but check with your rep.

AIX3 has attempted to be posix/ansi/bsd/sysv compliant, with a hierarchy of
priorities where conflicts occur.  Having ported several BSD programs to AIX3,
I can say that aside from the well-known portability issues, I have found no
suprises, and had a real easy time of it.

Yes, yes, yes.

I think that's a bit silly; much of the kernel is drawn from both sources,
and I can say from first-hand experience that the tcp/ip/socket code is almost
indistinguishable from BSD tahoe, except where we've fixed bugs.  As for the
rest, it seems well-structured and reasonably lean, considering that IBM has
put in a fair amount of security code and other "enhancements" aimed at
satisfying customer demand.  I believe that other systems (including BSD 4.4)
have had to do the same.

>10) Does AIX come with /usr/man/man* or just /usr/man/cat* ?

It uses "info", which contains complete system documentation, from how to
write device drivers to command reference.  I believe man uses this data and
formats it in the standard way.  The data is avaliable on CD, and can also
be loaded on hard disk.  My experience is that it's a bit slower than a
traditional man, but it's much more comprehensive.  It also features hypertext
links, which can be useful.

>17) How many buttons on the standard mouse?

Three.
