Now that I've read my own scan, I see:

"IIT Research Institute has just concluded an agreement with
Allen-Babcock Computing, Inc. of Los Angeles for extension of its RUSH
time-sharing system to IITRI clients in the midwest."

So the 360 (or this 360, anyway) wasn't even there at IITRI.

It appears they still exist.  Maybe I'll try to get in touch with
someone over there to see if there's any more computing history to dig
