CPU8 for iOS

Students or software programmers who want to learn how computers work will love this app.

CPU8 simulates the SAP-1 (Simple As Possible) 8-bit bread board computer that was famously the star of a series of videos by Ben Eater.

Using it, you can control a fully realized computer that utilizes microcode to illustrate the operation of individual computer instructions and their interrelationships with general purpose registers, program counters, memory registers, instruction registers, bus and memory though "control words".

In addition, CPU8 contains an assembler that allows you to write programs and convert them into the machine language of the simulated computer. A full programming manual is included.

Write, assemble and run programs using this 8-bit computer to see how the process works from start to finish.
