Do what I did with my first parallel-port Zip
drive--make an adapter
cable that siphons power off the keyboard jack. I used an adapter
that came with a (mumble, not Trantor/Adaptec) parallel-to-SCSI
controller. The Zip needs just +5.
Too little current avaiable, better put a P4 jack on the 5V line of your
"better safe than sorry" :o)
