General Information |
The 8008 was the first 8-bit microprocessor. The 8008 was originally code named the 1201. The Intel 8008 was a microprocessor designed for use as a terminal controller for Control Terminal Corporation (CTC). The 8008 was to be single chip version of CTC’s CPU design, which was to be implemented as TTL logic chips. Work began on the 8008 before the 4004 and had circumstances been different the 8008 could have been the first microprocessor and not the 4004. The 8008 is architecturally very different than the 4004. The 8008 was a very important transition CPU for Intel. The work on the 8008 enabled the creation of the powerful 8080 (which included the 8008 instruction set). The 8008 family is also referred to as the MCS-8. |
