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 through "control words". In addition, CPU8 contains an assembler that allows you to write programs and convert them into the machine language of the included 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. FEATURES - Assembler for the 8-bit computer (with manual) - the 8-bit computer simulator - 16 instructions - 3 pseudo instructions - 16 address spaces - control the speed of the simulated computer clock - single step through programs or run to the end - 7 sample assembler programs to get started - links to all the Ben Eater design and teaching videos - A short history of computing through the ages (37 chapters) Suitable for classroom study, independent study or just for the sheer enjoyment of playing with a computer that you can watch and learn from. No individual information is accessed. Oh, did we mention it has wonderful flashing lights!
