Nice one! I wonder if that book is online somewhere since it's the only
thing I haven't got.....

Tony's not far wrong with his guess (as usual :). The PSU I have in my
sweaty mitts here says 9V 800ma and I've tested centre (tip) positive. I was
going to say you could get away with a ZX81 PSU but they're 700ma and the
ZX80 is 600ma. Oh, the voltage I got was ~14V so it requires a load to bring
it down to 9V.
