Yes, but it doesn't need to be regulated. The original C16/116 series PS
was just a transformer, rectifier and filter capacitor. The 5V regulator
is inside the computer. So, just about any DC supply of 9 volts at 1 Amp
or more would work as long as the DC connector is a correct physical
match and the polarity is correct. That's important!
