Later a PC based assembler was produced by Systemation. Back to Top How was the Molecular programmed?
All programming was in machine code. Programmers wrote programs on pre-printed coding sheets. The sheets were ruled into rows representing consecutive memory addresses. A single sheet represented locations 0 to 77 (octal), one page of memory. The programs were written in a pseudo assembly language, and the translated by the programmer will being entered into an on-line core editor. (See note in section above regarding on-line program documentation.) Many of the common operations, such as file handling, arithmetic, and input/output was provided by sub-routines in the ‘operating system’.
