Cycle of the TMC0907NL from a WIZ-A-TRON manufactured in December 1978
flashing the display and captured with
the Digilent Digital Discovery connected to the DCM-50A Platform. TMC0907NL actually alternates between two completely different Display Scanning Cycles. (Note: The CK Frequency is set to 300 kHz and not properly displayed due to a sampling rate of just 150 kHz)  |
