IBM 1401 Symbolic Programming System


The IBM 1401 Symbolic Programming System was an assembler that was developed by Gary Mokotoff, IBM Applied Programming Department, for the IBM 1401 computer, the first of the IBM 1400 series. One source indicates that "This programming system was announced by IBM with the machine."
SPS-1 could run on a low-end machine with 1.4K memory, SPS-2 required at least 4K memory.
As the 1400 series matured additional assemblers, programming languages and report generators became available, replacing SPS in most sites.
