3-pin hdd power connector

Hi guys, I recently picked up a Compaq Portable 486c/66 for fun. It has no hard disk and as I was checking out the bay to see if there was something different in what it would take, I noticed it needed a 3,5" IDE disk powered by a 3-pin connector, not the usual large 4-pin molex power connector. It seems the Maxtor 7000 series was a series of drives with these added power connectors as well as some Quantum Fireballs of which I had one, but apparently has deceased on me. ?J3 ?
