- Short history review: Fortran was indeed written for the 704 and the
- mostly compatible 709, which were at the time IBM's fastest scientific
- machines, being word-parallel binary machines with random access memory.
- It quickly became popular and several versions of Fortran appeared for the
- 650, a slower but very reliable and popular digit serial decimal machine
- which used a 12000 RPM drum* as its main memory. The 650 was contemporary
- with the 704; work started on the 650 considerably earlier but both
- shipped in 1954. Probably the first 650 Fortran was FORTRANSIT which
- translated Fortran to IT, the 650 Internal Translator language from
- Carnegie Tech.
-
- The 1620 was announced in 1959 as a replacement for the 650. The 650, 704
- and 709 were vacuum tube machines, while the 1620, arguably IBM's first
- minicomputer, was all transistors. By the time the 1620 came along
- Fortran was the dominant language and all 1620s were shipped with a
- Fortran compiler.
-
- A good reference is "IBM's Early Computers," written by Bashe et al. (who
- should know what they're talking about because they were there at the
- time) and published by the MIT Press.
-
- * - Yes, I said a 12,000 RPM drum. Pretty amazing, eh?
