At Honeysuckle during the Apollo 7 mission:

Bryan Sullivan (left) checking spacecraft command data received via a teletype tape from mission control while Ron Hicks makes entries in the computer log book.

In the background is the Telemetry Computer and Mag. Tape unit.

Note the Tektronics oscilloscope displaying a circular lissajous figure. Items on the console besides an ashtray include a Motorola high speed printer, an intercom control unit and speaker as well as a precision timing device (Smiths cooking timer). The little timer was used during countdowns and mission operations to alert operators of significant events or when to make important keyboard entries into the computers.
