HP-35 Power Supply Waveforms

[albertofenini]

you are right, it is very well done, it's a shame that the author did'n complete the
card reader part.
However my breadboard prototype is exactly like the circuit shown,
and that's why I don't understand why my values are higher.
As you see, they suggest to measure Vcc, Vgg and Vss off load.
I'll check it again ... but if you have any idea ... let me know
thanks in advance
