Guess I have to read more to understand why it's putting me in a math expression evaluation (?) `Z` prompt (which I haven't found mentioned in a manual) rather than the `*` command prompt.
EDIT 2: Seems `eq` is the proper way to exit on this TECO:

I don't see that mentioned in other manuals online. I guess this TECO is different from others?
Not totally fair as you should compared with Tso at least. Or with ispf (major edit our NS still like it more for line editing and hence vi guy now but still ...). Of course you have vm.
Having said that I was surprise after reading the Multics myth and its story against bell unix is that it is all pr. or the winner took it all. And sort of rewrite the history.
Happen to know a good "getting started" site or book for MVS? I rescued a small S/390 from a metal scrap dealer and, if the Gods of lost software smile on me, would like one day to have it up and running again.
The tarpit feature is not appreciated - it showed "Scanning host..." and then the visual challenge (on the level of an AoC task) timed out immediately and started slow-sending me data. Fun to code I'm sure, not so fun to be on the receiving end. Oh, and it also seems to have banned me after that one try.
>Pat Coulson, an NSA spokeswoman, confirmed the 1986 security breach of Dockmaster, which she said was discovered six days after the "first known misuse" of a password and compromised information used by an unnamed corporation.

shipyard?"
>They whispered among themselves, and Mr. Big nodded. Greg explained,
"Dockmaster isn't a Navy shipyard. It's run by the National Security Agency."
>A hacker breaking into NSA? Bizarre. This guy wanted to get into the CIA, the
NSA, Army missile bases, and the North American Air Defense headquarters.
>I knew a little about the NSA. They're the secret electronics spooks that
listen in on foreign radio broadcasts. They launch satellites to listen to Soviet
telephone calls. I'd heard (and didn't believe) rumors that they record every
overseas phone call and telegram.
Here's some discussion about Dockmaster, which was on MILNET IMP 57, and the rumored "explosive bolts" on the ARPA/MILNET gateways:
DCA must have the ability to partition the ARPANET and MILNET in
case of an "emergency", and having non-DCA controlled paths between
the nets prevents that. There was talk some time ago about putting
explosive bolts in the mailbridges that would be triggered by
destruct packets... That idea didn't get far though...

I only ever used video terminals — i.e. ASCII terminals that may have interpreted the ANSI position in commands. There was a also SUPDUP server for Multics. The only program I used that did cursor positioning was emacs.
“Graphics terminals”, in the sense of bitmap displays, weren’t common throughout most of Multics’s life. The first one I ever used was the Alto.
Though keep in mind that Multics was more for the business[1] side of things, despite being developed at MIT. ITS was a hacker's OS, it was going to have more cool stuff.
EDIT: Got it :P
