Description

Object is a metal box containing a power supply and a motherboard with four circuit boards plugged into it.

The front panel has a large power button. The rear panel also has a switch labeled "Power", and three RCA jacks labeled VID SPK and MIC. A keyboard is attached via a narrow ribbon cable that connects to one of the circuit cards.

From the rearmost board emerge the multiple thin gray cables that are connected to the CRT from this lot. These wires include two small home-brew circuit boards and wires attached to sliders (speculatively, for contrast and brightness?) One of the two sliders broke off from the fine wires it was connected to while the object was being packed. It is bagged and attached.
