the And years before that - SCO XENIX and then SYSTEM V Unix - we were told the same thing, though this way sync sync sync shutdown / halt (or whatever the command was) Delurking here for a bit. My sole collectibles are TI 990's and the TI PC (the first computer I owned). Most haven't been fired up in a while. Was once a field service tech for TI way back when. Still have a good bit of documentation and half-forgotten knowledge of those machines. I also know a much smaller bit about the TI Unix and LISP boxes. FWIW. Guntis.
