RE: HP 45 High Precision Timer

One forum member asked for schematics of HP 45 High Precision Timer versions. Thank you because up to now I had only hand sketches...

Unfortunately Si501 programmable oscillator of version 2.0 went out of production in 2016 and you need a programmer for it. As I have some units left I can still produce some boards. LTC6900 of version 1.0 is still available.
