GE added Multics support to the 635 to make the 645. The 645 was a transistor machine and was reworked as an integrated circuit machine, the GE-655. The 655 was rebranded as the Honeywell 6000 series. I am not sure of the evolution path of the 635 to the 60xx; ie. if GE had an IC version of the 635 and what it was called, or it the 655 came with a non-Multics support version. -- Charles
