The Pep/7 Computer Simulation (also known as Pep7) is a virtual machine that is used by professors of schools and colleges to explain and simplify the lowest level of computing (machine language). True to its name, Pep/7 has seven registers and four status bits. The Pep/7 is a direct descendant of the Pep/6 virtual machine, the only major difference is that it has been expanded from 4KiB to 32KiB of system RAM. The machine code format remains the same.
