This probably would have been early '60s, so about the same >timeframe. Here's the manual, second edition dated 1964. I don't think the 360 architecture was defined until at least 1963 so this would be a little later than 1960: https://bitsavers.org/pdf/ibm/7090/C28-6501-2_7090_SupportForSys360_Nov64.pdf In 1957 IBM had a program for the 705 to simulate a 650: https://bitsavers.org/pdf/ibm/705/32-7763_Simulation_Of_650_On_705_1957.pdf Back in the 1950s before there were compilers there were interpretive systems that interpreted programs in an idealized machine language that was easier to program than the underlying machine. That was sort of the same idea. -- Regards, John Levine, johnl@taugh.com, Primary Perpetrator of "The Internet for Dummies", Please consider the environment before reading this e-mail. https://jl.ly
