I set the clock / calendar that was totally wrong as expected, but by turning the power off and on, the settings are lost. I was very happy to see the apparently normal screen. Visually it's very good, so I turned on the power to see how it works. I bought it at a local auction and I already expected it to have some problem. I just received a Tektronix 2712 that I wanted for a long time.
