Way back in 1981, IBM released the first generation of its Personal Computers with an Intel 8088 CPU chip inside. From that time forward to today, one of Intel's most important design goals has been to provide backward compatibility in the interest of preserving the investment of its existing customer base. Intel hardware designers have continually ensured that programs written for its older chips continue to run, unmodified, on its newer chips. This original 8088 CPU has only 16-bit registers. Even today, on the Pentium 80x86 CPUs, these same registers still exist. Required:
