Here is as much as I know, any help is appreciated. I recall it had a cardboard overlay for the keyboard. The view was cockpit out, 3d-ish. I recall there being a grid coordinate system and the main purpose was collecting artifacts. Likely from the 1990s. Angular spacecraft design. Maybe started with a Z or X. Help!
