That would work, although if you can find a regulated power supply with 9V, 2A (or more amperes), the internal voltage regulator won't heat too much.7805 on PlusD needed?I am planning a batch of PlusD interfaces.

Only if you connect more interfaces to the Spectrum. With too many interfaces the current draw on 5 Volt can exceed 1 Ampere and will be dangerous. Drawing it from 9V leaves more mA for other peripherials.Game Redux's you'd like to see?I was talking about this with one of my pals at work the other night, about which games you'd like to see redone?
