At first, however, the only method to reprogram ENIAC was by rewiring it.
An x86-64 compatible microprocessor like the AMD Athlon 64 is able to run a lot of the similar programs that an Intel Core 2 microprocessor can, in addition to programs designed for earlier microprocessors just like the Intel Pentiums and Intel 80486 This contrasts with very early commercial computers, which were usually one-of-a-variety and completely incompatible with different computers.
