I think I've got it. There was a pre zoids toyline released by Tomy called Scitex which was knocked off, altered/expanded and released as a toyline called Multimac.
I'm certain that the Multimac are what I had, and probably what you had as well.
Found a small album with a few pictures here https://www.flickr.com/photos/microb...7625328845058/

Here are a few more pictures I found by searching for Multimac (having the name makes that so much easier lol)





Are these what you were trying to remember?
