Panasonic HHC ROM 'capules'

[Paul Berger (Canada)]

Reading the technical information pamphlet I don't think that anything would be powered when the All Off switch is open. It states that the switch turns off the power to the CMOS chips and if you look at Tony Duell's schematic he labels this as "VRAM" which also appears to power the Y driver chip which is the chip that supplies the "CPU ON" signal that turn on power to the processor as well as all the NMOS and TTL.
