If they have a 68020 and the memory is soldered onto the motherboard 
then it is a 3/50.
If they have a 68020 and use 30 pin memory they are Sun3s. Most 
likely a 3/60 or 3/80.

If they really are Sun2s then the memory is soldered on to the 
motherboard on a 2/50 or soldered onto a Multibus board on a 2/120 or 2/170.
