Designation would be: SS20/71

As far as I can tell, the formula for SS10's and SS20's is as follows:
	UNIT/sen
	  |  |||
	  |  ||\------	number of cpus. blank = 1 cpu
	  |  ||
	  |  |\-------	external cache. 0 = no, 1 = yes
	  |  |
	  |  \--------	cpu speed. 4 = 40MHz, 5 = 50Mhz, 6 = 60MHz, 7 = 75MHz
	  |			   8 = 85MHz (?), 15 = Ross 150MHz hypersparcs
          |
	  \-----------	base type. SS10, SS20, SC1000, SC2000


So, I've seen/used:
- SS20/152	SS20 with 2 x 150MHz hypersparcs
- SS20/712	SS20 with 2 x 75MHz supersparcs + ecache
- SS20/514	SS20 with those horrible boards with 2x50Mhz Supersparcs
		on one double width mbus card. ack!
- SS10/40	SS10 with 1 x 40MHz supersparc without cache.


I think that's right, anyway...
