	As long as the company was 
	
	1/ small...10Base2 segment length limited to 185m max
	2/ had 30 connected machines or less ...max nodes per segment 30
	
	of course with repeaters and bridging you could build a *big* Ethernet ;-)

	10Base5 (Thick Ethernet): 500m segment, 100 nodes/segment 

	BTW, TimeDomainReflectometry used to work relatively well to locate
	breaks (or unterminated connectors) in the cable.

	Remember those days well...
