Yes but what is the Amdahl Corp 7300 IBM 370 architecture mainframe specifically adapted and configured to run Unix efficiently (CI No 1,301)? Turns out that the starting point was Fujitsu Ltd’s M760 mainframe, which comes in below the top-end M780 and covers the performance range of high-end models of the IBM 4381 and low-end models of the 3090: Amdahl says it has made substantial modifications to the machine to optimise it for its UTS implementation of Unix, but has not yet said whether these modifications extend to adding Unix-specific instructions to the basic 370 set.
