Yes, that sounds like what they're called :^) Couldn't think of that.

Let's see, they're quad height boards. They're a combination of 14 and 16
pin chips. They're on a 12 x 6 grid of chips, with 5 spots not having
chips, two of those spots have resisters in them. Two of the chips say
Beckman on them and a grey instead of black. It's got some other
components on it that I can't identify.
