Re: Speaking of remembering
@Earl Grey -
LCS, I think little old ladies with needles, threading cores.
Note that S/360 could be programmed from the panel as well, you just had to write in machine code, in hex, a bit like kick starting a PDP8.
BTW, Fred Brookes got the job managing S/360 since he did so well on a special project for a 7000 Series "super computer", the 7030, better known as Stretch. Some of the 7000's were a bit compatible with each other I think, at least used the same data format, 36-bit words, one's compliment integers, 7090 and 7094 were sort of compatible. There were all sorts of 70x0 machines that weren't though.
I spent a bad summer working on old Fortran code which ran perfectly on a 7094 and not at all on a model 50.
