The green VFD (Vacuum Fluorescent Display) in action.

The display is assembled from single tubes.

To access the electronics of the Toshiba BC-0802B the keyboard
has to be removed. Please notice the magnetic switches.

The whole electronics fits on one PCB (Printed Circuit Board) thanks
the Texas Instruments single-chip calculator IC.

A closes look on the TMS0112 reveals Toshiba itself as manufacturer
of the Integrated Circuit ! The circuit was assembled April 1972!
