This application simulates a very simple microcomputer based on the 4917 processor (a hypothetical device designed just for a computer course at the University of New South Wales, Australia) which was used to teach microprocessor basics. It is 4bit, has 2 internal general-purpose registers and works with 16 memory locations. Each memory location can store a number between 0 and 15, and there are 16 instructions. Write your own programs using hexadecimal notation, load them into memory, run and debug them just like programmers of 1950's!
Author of the application is Michael Balandin.
CPU 4917 is made in "smart BASIC" programming language and is published using smart BASIC SDK for Xcode.
