strange armada 1 glitch

[HrdWodFlor]

I just found an old copy of armada 1 in my local thrift store. I have played it up to the dark omens level where i have to destroy the borg base. I did all that but there was a small grey cube that showed up on the mini map and on the edges of a ships sensor range. but would disapear when a ship got to close. when i zoomed in on the object i saw what looked to have the words (go2 770) i think they are sevens the sort of look like backwards F's.
any help or ideas would be great. I want to finish the game!!!
