TermOS/ThinkDOS Explanation (Request?)

[Embolism]

Speaking of TermOS, can someone explain to me how to reboot Zeta's DWAINE network? I tried following the instructions in the recovery box but I can't get it to work: I connected a databank through one terminal, inserted the recovery tape, turned APC power on and off, then connected to the mainframe with another terminal; but it still won't let me login.

I suspect I'm doing something wrong with "cycle mainframe power": presumably only the mainframe should be turned off and on, but the Zeta APC controls all power in the station so I can't really isolate that...
