Correct. The 2/120 does, and the Sun-2 SCSI shoebox, both for use with the (8”) 
Archive Sidewinder QIC. The 5v/24v power lead has two connectors, meant to 
power the Sidewinder and the Sysgen SC4000 QIC-02/SCSI bridge. The latter only 
requires 5v and has nothing connected to the 12v/24v pins.

The 2/100U, 2/150U, and 2/170 have no internal storage devices, and the VME 
Sun-2 machines use 5.25” QIC drive models with the 5v/12v molex everyone 
expects.

ok
bear.
