I have recently acquired Venix for the PC/AT and have run into a few problems,
and was wondering if others out there (there MUST be others :-) ) had run
into them as well....
 1) date/time on bootup is sort-of correct..month, day and time are correct,
    year is always 1970
 2) awk(1) does not handle the BEGIN pattern correctly..it hangs the process
 3) curses(3) routine getstr does not return when RETURN pressed..have to
    hit ^J (that took a while to stumble into)
 4) awk(1) does not handle this type of command line properly:
	awk -f prog filename
    it just hangs there

Some observations:
 1) though I could not find it anywhere in the manuals, I have discovered
    that kill -2 1 causes /etc/ttys to be re-read..sure beats re-booting as
    the manual's way to re-configure your ports
 2) arbitrary-length reads directed at a tty in raw mode
    block until the number of characters
    requested are input. THIS IS MENTIONED in ONE (1) PLACE as far as I can
    see, and not well marked.
   (in thinking about this, it might be why getstr screws up)
    This means, among other things, that stdio can not be used in raw
    mode (I have some public software which does this), as the old
    _filbuf does a read of BUFSIZ. cute
 3) performance is pretty good

Has anyone put the floating point processor in? how does venix live with it?
How about the AST Advantage card??? Anyone with it?
And of course, the 64 dollar question, what about second source hard disks?

I would appreciate hearing from those hearty souls who are running Venix
on a PC/AT....

   as they say, thanks in advance

I have VENIX running on my AT, and in fact wrote the Hard Disk driver
which is used by VENIX.  Some responses to your questions follow:

Not a problem on my machine.  Check that you have used IBM's 'setup' properly.

Sorry- I avoid using awk on any machine.  It's too slow even when it works.

You probably want to use CBREAK rather than RAW mode.

This is the historic method used by V7 derivatives.

This is very true,  although it has hidden benefits for things like
uucp that want to read 64 bytes RAW, and need all of them before anything
can be done.

I haven't been able to get the FPP, but it does work on machines that have it.
I have an Advantage card in my machine, and am about to load it up with those
$8.00 256K RAM chips that are now available.  As far as second source hard
disks and VENIX go, here's the poop:  If the disk matches one of IBM's disk
types as listed in the TR, fine.  If it doesn't, you'll need a later version
of my disk driver, that can handle 'odd ball' disks.  In particular, the
Maxtor-140 is one of these.

One further bit of advice:  Pop for the $1.59 and get a 15Mhz crystal for
the AT.  The 15Mhz seems to work well, and even though it runs the 80286
over spec, it won't be running the 80287 over spec.  The 286 will be running
at 7.5Mhz and the 287 will be running at 5Mhz.  I think this is
a reasonable compromise.  With a 15Mhz crystal, the 80286 out benchmarks
a 10Mhz 68010 when running the drystone benchmark (balanced statement
mix, variable types, but no floating point or disk).

I'm currently running an AT with a 80287 and 512K, but no hard disk.  Could you
give me a source for a 15Mhz crystal?  Sure would appreciate it.
