ibm science center was on part of the 4th flr of 545 tech sq ... some past posts http://www.garlic.com/~lynn/subtopic.html#545tech
but the machine room occupied part of the 2nd flr. it had duplex (two processor) 360/67, 768kbytes memory, three 2301 "drums", five 8+1 drive 2314 string plus one 5 drive string. The IBM CE painted each 2314 string a different color ... so mount/unmount 2314 packs on specific drives could be more easily identify which string. on one side along one wall ... right next to floor level ... the 4in (6in?) water pipe from air conditioned units poured directly into 8in sewer pipe (bldg. codes required air gap). the (virtual machine) cp67 development group split off from the science center and took over the ibm boston programming center that occupied part of the 3rd flr (the rest of the 3rd flr was listed as lawyer firm, but the telco closet was on the ibm side, and clearly labled it as a 3letter gov. agency) ... where they got a 370/145 with (unannounced) virtual memory for development of vm370 (morphing cp67/cms into vm370/cms) in their own machine room. MIT Multics was on the 5th flr and they had (multics) GE645 machine room. city of cambridge wanted to pass a water conservation ordinance and cut flowing water directly through air conditioning units and straight into the city sewer ... however, it turned out that bldgs. had not been designed/built to handle weight of recirculating water towers on the roofs.
