[rescue] Terminal servers (was: Just a thought - what would be a good starter SPARC system these days?)

[Steve Sandau]

I had a Linux box (a 386!) with a Boca 4-port connected to 4 VT-100
terminals. Worked great, no problems, had it up, straight, no reboots,
nothing, for well over 2 years. Uptime on a PC running LInux rolls over
at 490-something days, so I had to scroll through the logs to find out
how long it had really been up. Worked great, though.
