Mine came with the power brick (it's more of a cube-on-a-wire), but I don't
know if it came with the calculator. I assume it did - the calculator would
be pretty useless without it.

This one's been sitting in a cupboard for roughly twenty years and it still
works flawlessly. Unfortunately, being the clumsy idiot I am, I went and put
a scratch in the back casing while I was trying to remove the corroded power
connector. Even after a liberal dose of WD40 the locking nut refused to
budge. In the end I grabbed the connector with a pair of heavy-duty
sidecutters, snapped the plastic casing and destroyed the thread on the screw
fitting. Needless to say, the locknut fell off rather quickly after that
treatment - it had corroded onto the screwthread. Bah.
Anyone know if there's a way to repair scratches in plastic? :)

On a lighter note, I've managed to fix my dead Acorn A4 with the aid of a
pair of 0.33 Ohm 0.6W flameproof resistors. There are two of them fitted
between the 6-pin power connector and the IDE connector. After a half-hour
desolder-and-replace session, the machine came back to life. Now I need to
fix the wretched display data flat-cable - it's got a crack in it :-/

Later.
