Yep, a great game...they're out there. It was a grail game for me for years. I managed to find two over the years, and still have one. Not to glote... Here's mine in the dark to hold you over....
Hey there OHEMIO, looking at your sig, it looks like you've got quite the EM collection going yourself. My list is no where as long as yours.
Kovalski3 - I'm the guy with the Target Zero for sale...if you're asking me what EM games I have, I have:
Bally Space Flight
Bally Road Runner
Bally Target Zero
Bally Space Time
Williams Skylab

That's it.
