I have just been informed by GSB that he made a crash dump of an ITS that
had died trying to read an ML backup tape last Friday.  Since it looks like
this is a repeatable error (DLW crashed MC a couple of times trying to read
in an AI backup tape last Sunday), its probably worth looking at.  Note
that there seems to be no trouble reading in MC's backup tapes.  The dump
GSB took is in CRASH;STACKP FUCKED.  If you look at what's in P you will
understand the name.

    I believe so.  But so certanly was the University of Manchester Atlas,
    Multics, and possibly the Berkeley XDS 940 time sharing system, although I
    don't know if it counts a demand paged.

    Oh, yeah, 360/67, TSS, CP/CMS, probably also both predate Tenex, but I'm
    not sure..
Foo.  You know I meant on PDP-10s.
Didn't ITS start out Base-and-bounds?

    Re:   bizarre dialup error
    To: KMP @ MIT-MC

    The weirdest thing happened to me.  I dialed up MC from
    home, hit a carriage return to get ITS attention, and it echoed the
    CR, but didn't print out any msg.  SO I hit CR again, and again it 
    echoed it, but no MC ITS ...
    so just to see what was going on, I said ":versio" and it said I was
    MC ITS USR:ING.  IS THAT THE STRANGEST THING?  I did whois on this
    ING and he is some tourist on the system.  But I got logged in as
    him without ever saying login or giving a password.  I am really
    psyched out by this.  Do you think I should send mail to bug-its?
	    --pk

This isn't the first time such a thing has happened. Your guess is probably
correct; ING somehow hung up without ITS noticing so when you dialed in,
you got his already-logged-in tty line. I'm forwarding this to BUG-ITS
in case they care, but I wouldn't lose any sleep over it.

    When I supdup to MC, if I get tty 50, most characters do not echo and
    are not obeyed.  Only rubout and control-G get any response from DDT.
    :TCTYP TTY 50 DESC shows exactly the same thing as other ttys that
    I get which work properly.  I locked tty 50.

The exact thing has happened to me before, too, many months ago tho.

I'm unable to supdup to MC right now, because the supdup server claims that
all network ports are in use, although only t42-t51 are in use.  nsttys is
27, so we should be able to do better than this.  The ttys actually seem to 
be there; could this be caused by someone not reassembling the supdup server
after the last system installation?

    DATAI 24,n executed in user mode clobbers locations n and n+1 in the system!
    It's a good thing I tested this by hand before writing a program to use it.
    ITS executes the instruction with XCTR, as it should.  I suspect this is
    a bug in the microcode.  I guess I'll use .suset [.rrunt,, like a good little boy.
    -------
    I looked at the microcode and now think it's a bug in the hardware (MCL board
    of course).  EPT REF clears the flag that SET PXCT sets?

Fixed in the source of ITS!  (Cleaning out my mail file).
