The Model 65 was a member of the first generation (Models 30, 40, 50, 65, 75) of the famous IBM System/360 series of mainframes. As the biggest of the microcoded System/360's, it sat at the mid high-end of the spectrum.

All that remains now of this once great machine, which cost around 4 million dollars back in 1968 (equivalent of 27 million of today's dollars), is the operator's console panel.

These console panels were used to control and monitor di fferent parts of (mainly) the CPU.

I'm connecting this console panel to a simulator of the Model 65 CPU. Progress on that project can be found here. Read about its acquisition here: IBM 360 Console Panel Arrived.
