What was this board used for?
I have one in each of my imsai's and can't find any info on it.

Keeps the bus noise down. Good thing to have in there.

What Chuck said. Your IMSAIs would probably work OK without them, though, unless you have non-standard CPU or memory boards installed.

Hmmm... I like to think of terminator strips as the "shock absorbers" of the S100 buss. Take 'em "OFF" the buss, the driver provides a bumpier ride.

Herbert R. Johnson has docs (per his website) for the CCS terminator.
