   Several of my B&W games have some monitor funkiness I need to fix. Space Encounters had a bit of flicker happening after a few hours running.

   Didn't have a key to the upper back door, but I save any keys I come across and have a ring with several dozen on it, one of which opened it right up.

   And... Yep, original caps in here, date code 8052, so somebody spent Christmas week 1980 manufacturing this monitor. It's almost as old as me, and nearly as tired to boot.
