Normaly when HP change some from A/B it's due to production that has change. Like new version of the flopy driver or the power.
The specification are the same. Same MB on the floppy etc.

One difference, if I remember correctly, was that the B version added LED's on the front panel that showed the approximate remaining amount of battery life. That was very helpful since the drive is so power hungry.

I have both drives in my basement - the B model in addition to the extra LEDs also used a different, slimmer, drive (1/2 vs 1/1 height?).
