Inside The Guts Of A Rally Clock

[hr369]

errr... i meant insides of a rally clock oscillator.  Anyways....ran across this page in japan. this guy is an electronics guru that fixed an

oscillator. I had never seen the insides of one before but there sure are alot of things that can go wrong. No wonder they use so

much juice. with no schematics to work with he succeeded in finding what was wrong. a burned out transistor.

Man, the electronics in the rally clock really date the design don't they? Sometimes we forget that the original Z was built in the era of slide rules.

(When some at IBM still believed that the world really only needed a few dozen computers.)

 

I remember the first quartz crystal watch I ever owned, a Timex. It was given to me as a high school graduation present, and was worth over $100. We were all astounded by the accuracy. It was guaranteed accurate to within 15 seconds per month, which was unheard of at the time.

 

Maybe that is why I have never even considered replacing the original clock in my car. It still runs, and so long as I set it every day it keeps reasonable time.

hey, the clock in my z (original) keeps absolutely perfect time - to the second.

and the expensive stereo that i installed with a fancy lcd display which includes a clock (unfortunately no way to turn it off) loses 5 minutes every 3 weeks!!
