By the magic of turning a Master upside down I discovered a label
with the relevant information. It turns out it's less, not more.
BBC B Master
+5v 1.25A 900mA (0.9A)
+12v 1.25A 1A
-5v 75mA (0.075A) 75mA (0.075A)
More than plenty to drive two IDE drives at 225mA!

Taxation is like diary farming. You have to extract the maximum amount of
milk with the minimum amount of moo.
