My 40MB Unix PC 7300 also uses that exact supply.
  There seems to be some confusion about what you call
the 67MB UNIX PC.  Is it
 a 3B1 or a 7300? 
Never was clear on that myself.  My 40MB system says "PC 7300" on the
bottom, but has a full height 40MB drive ("hump" in the case to clear it)
+ the power supply mentioned above.  Would it be considered a 3b1?
