As I understand it, the 370 > is basically a 360 with vm. Almost right. There were a fair number of 360/67's and 370/168's running the TSS 360/370 operating system. The Bell Labs Indian Hill computer center had (I believe) six /67's and /168's at one point being used for hardware and software development for Electronic Switching Systems. To make the 360/67, a unit called the Direct Access Translator (familiarly known as the DAT box) was added to a 360/65. This hardware was included in the 370 machines. The DAT box could be turned off to make the machine back into a /65. At the Indian Hill Computation Center when the 360/67 was introduced, it was used as a /67 during the day running TSS, then was switched back to a /65 to help process the backlogged work on the OS side of the computer center (as one of as many as six slave processors on an ASP network).
