looks like an old type printer ROM cartridge, to hold additional fonts for a printer.
newer ones would use proms to save money, but the initial production would use eProms so they could make changes to the code.

| Maybe a prop from Stargate, that thing must be the special command key that powers one of the bad guy's spaceships. |
