questions about HP 802059 wall warts
I just acquired a new (to me) 802059D (edit: 82059D) charger that came with an HP 9114B disk drive. I have always wondered why HP decided to have their wall warts supply AC voltage when most other wall transformers/chargers supply DC. Now, please understand that I can by no means be labeled as someone knowledgable in electronics. Knowing HP, I'm sure there was a good reason. Anyone know the reason?

The manual for the disk drive states that an 82059B charger should be used. This one is a 82059D. The no load AC output, measuring across the terminals, is 12+ish VAC on this one and on my other two 8205B chargers as well. I am assuming that the D model is a later manufacture than the B and that they are interchangeable for 40 series accessories. Is this correct?

In order of appearance: HP 41CV, CMT-MCGPS, HP 41CX, DM 41, DM 42
