As I rarely have that many of the old machines powered up (or even set up) at 
the same time, I just hook up the appropriate cables at need.  There's a 
getty on the serial card ports full time.

The first serious network I ever installed was a couple of hundred Mod 16 
Xenix systems scattered across Southern California and Arizona at all of the 
Southern California Gas Company's pumping stations.  Data was collected in 
Multiplan spreadsheets which were uucp'd to company HQ at 820 S. Flower St. 
in Los Angeles every night to be merged in the AM.  I was the CSR at the RSCC 
a couple of blocks away at 740 S. Olive.

My Mod 16 at home a little later was a leaf node dialing into Cal Tech for a 
partial newsfeed at 1200 bps.  Very partial, as 12 Mb won't hold much even in 
1986, when a full feed was maybe 15Mb per week.

should understand what an expensive proposition it is to cohabitate with
a narcissistic woman built like a stripper.  --  Tony Woodlief
