The background drives are probably 607's or 609's--the photo's too 
fuzzy for positive ID--but my money'd be on 607's which were far more 
common (I loved those drives and despised the 657 "cost reduced" 

Unfortunately, there are no mainframe cabinets anywhere in the photo--
what you see in the foreground are 3000-series controllers, but that 
doesn't mean a thing, as both the 3000 and 6000 series used 3000 
peripherals for tape., card and printing.  The 6000 used a 6681/2 
channell converter, which then would interface to, say, a 3423 tape 

The cabinet sitting next to the 415 card punch in the middle 
foreground is probably a 3447 punch controller.

Maybe Billy Petit can recognize some of the cabinets--it's far too 
fuzzy to make out any numbers.
