I just bought a quarter-inch Archive tape drive (model 2150S, if it
matters).  It's a half-height drive, and I was planning on mounting it
in a standard half-height floppy disk drive enclosure.

However...  the power supply in said enclosure only supplies 1 amp of
+5V, and 1.2 amps of +12V.  On the tape drive is a little sticker
reading

	+5V  /  17.5W
	+12V /  48W

It looks to me as if the power supply will be severely overloaded, to
put it mildly.

I don't have the manual for the tape drive yet, so I'm forced to ask
the net:  are those figures reasonable?  Will the tape drive actually
use that much power?

If so, then my enclosure (bought from Jameco) obviously won't cut it.
Does anyone sell half-height (or even full-height!) enclosures
equipped with heavier-duty power supplies?
