My Coco needs to warm up for about five minutes before it will reset
properly and run right.

I suspect that the electrolytic capacitors in the power supply may have
degraded over time.

I have made some voltage measurements and would like to compare them with
working CoCo's.

I have a CoCo 3 and I'm making my measurements on Q1.

 

Q1 Measurements:

  1 Base) 5.64V

  2 Collector) 11.22V

  3 Emitter) 4.99V
