Here is what I got from the local Tandon sales office.

The TM55-2 (which uses a Hall effect motor) has a current surge of 1.4
A for 50msec.  The person I talked to said that it can be as high as 2
A.  For the TM50-2, the current surge is 1.3 A. and he said that it is
probably less (around 1 A).  The steady state current for the TM55-2
is 900 mA and for the TM50-2 it is 800 mA.  I got these numbers over
the phone, the data sheet is being sent to me.  He made a claim that
two TM55-2's draw as much current (not sure if it is surge or steady
state) as a Winchester.  So his advice is: if your power supply can
handle a Winchester then it can handle two TM55-2's.  I don't have the
numbers for the power supply of the PC and hence cannot say if he is
right.

Regarding mounting the TM55-2 one on top of the other, his advice is
to use two side screws on one side only instead of on both sides of
the disk drives.  Brackets (costing about $3.00 a pair) are available
from mail order places for mounting them.  There is enough clearance
in the PC for mounting them with a small (guess: 1/4 in. to 1/2 in.)
gap separating them.  This is important if you have the TM55-2 since
the microprocessor on top of it prevents two of them to be stacked
directly on top of one another.

Rumor: He also said that the trim-lines will be used in the Peanut.
It'll probably be the TM50D (or was it TM55D?) a direct drive version
of half-height disk drives.  The TM50's and TM55's are currently belt
driven.
