{{ti title|TMS1000 Series}}
The '''TMS1000 Series''' was a [[microprocessor family|family]] of [[4-bit architecture|4-bit]] [[microprocessor]]s designed and manufactured by [[Texas Instruments]] in the early 1970s. Originally made using [[pMOS logic|pMOS]] technology, TI later expended the family into [[nMOS logic|nMOS]] and [[CMOS]].

==History==
In September of 1971, the [[/tms1000|TMS1000]] was completed. It was the first microprocessors ever created, designed by [[Texas Instruments]] engineers Gary Boone and Michael Cochran. Gary patented the invention on Aug 31, 1971. On Sep 4, 1973, he was awarded [http://www.google.com/patents/US3757306 U.S. Patent 3,757,306]. Unlike Intel's chips, TI's was not placed into the general market until 1974. Instead TI used the chip for their calculators.<ref name=smithsonianchips>[http://smithsonianchips.si.edu/augarten/p38.htm The Most Widely Used Computer on a Chip The TMS 1000]</ref>

After being slightly refined, the chip was released to general market in 1974. A few dozen different variations were created with various ROM and RAM sizes.<ref name=smithsonianchips /> Due to its cheap price, the TMS1000 family enjoyed a tremendous success in consumer electronics being used in everything from calculators, toys, games, and various appliances as well as photocopying machines and juke boxes.<ref name=smithsonianchips />

== Overview ==
The TMS 1000 had a relatively simple design with only 43 instructions and 2 general purpose registers. Similar to the [[Intel 4004]], the chip only had a single level of stack and no interrupts.
