well, it was like 19 years ago... I just downloaded one of those free fonts that said it was the terminator font. I remember there was more than one and they were not all the same (some letters like the 'A' were different.) You could probably just download a bunch of them and see which ones look closest. A quick google brings up one font called "Terminator Two" which could be it, but maybe not. Another good way to tell them apart is the numbers look different in the different versions available. So find the one with the matching numbers.

Fun fact, I have actually made a new font from scratch about 5 years ago to use for rubicon 3, which is kind of a hybrid between terminator and micgrogramma. Of course rubicon 3 doesn't exist, but this font still does.

Also, when I was making that I did some research and found that the terminator logo was adapted from a font from the 70s called "China" owned by VGC. There is also a recent commercial font called Changeling Neo based on China, but with lowercase letters added. But it's not free and of course it wasn't the one I used for Rubicon 1, if that's what you're trying to track down.
