This small regulated power supply was found in a 1963 General Electric documentation. The special zener diode transistor can be replaced with an equivalent discrete configuration.
In the figure we have 3 CMOS monostable circuits that can be used as anti-bounce switches. The...
We found this circuit in an old American publication from 1975. It can use almost any common FET...
This Vienna bridge multi-band oscillator circuit was found in a 1974 Ferranti transistor manual. The...
