On the other hand there are Archive tape drives that used +5 and +24V
with the same power connector as a 5.25" floppy drive. Thankfully they
kept the 5V and grounds in the same place.
I am told some Sun machines had power cables for both disk drives and
said tape drive, the only difference was the colour of the wire
(yellow for 12V, orange for 24V) Sounds like a source of magic smoke
emission.
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.
