Found in documentation from the 90s, this circuit triggers a relay with inductive signals applied to a link. The sensitivity depends on the frequency and the power supply depends on the relay used.
This variable frequency oscillator (VFO or OFV) was obtained in an old Motorola documentation. The integrated...
This electronic ignition circuit was found in Motorola's Linear Databook of 1990. The components are not...
