Inside

Inside, from the rear, showing a stack of narrow circuit boards at the back, about five larger upright boards in the middle, and the "Nixie" type display tubes.

The integrated circuits on the nearest board are in 16-pin packages and so are probably SSI (Small-scale integration) or MSI (Medium-scale integration) devices.
