Troubleshooting the Standard 16 Foucault Pendulum

Several modifications were made on the "Standard 16" especially in the electronics. The 50's used a pit switch and tube electronics. The 60's used early photo SCR's. The 70's and early 80's used a banner module (model MB4). The late 80's to currently use a Banner CM5 module.

Other changes included the installation of O'Rings on the safety plate hub.
