I have a dual disk drive ZF-148 with the optional daughterboard which
enables use of a single expansion slot.  (The ZF-148 is an older low
profile machine with little expandability.)  I'd like to install a
hard disk but am unsure whether the 65 watt (non-replaceable) power
supply could handle one.  I've heard that some of the newer 3.5"
half-height hard drives draw less power but haven't confirmed.

1. Has anyone else upgraded (or knows someone who has) a ZF-148 to a
hard disk?  Can it be done?

2. Do the higher speed hard disks consume more power than lower speed
(say, 65ms vs. 28ms).

Specifications: ZF-148, 640K, 2 disk drives (1 to go), serial mouse.
I don't know how much power each of these consumes.  Everything else
has its own power source.

Thanks for any help.
