DEC T-11
TheT-11,also known as DC310 or DCT11, is amicroprocessorthat implements thePDP-11instruction set architecture(ISA) developed byDigital Equipment Corporation.The T-11 was code-named "Tiny". It was developed for embedded systems and was the first single-chip microprocessor developed by DEC. Going into volume production in early 1982,[1]it was sold openly and was used by DEC in disk controllers (Eg: M8639 RQDX2 controller), theVT240terminal, auxiliary processors and in theAtari System 2arcade game system.It operated at 7.5 MHz or 10 MHz (three versions, two speeds), used a 5 V power supply and dissipated 1.1 W maximum. It contained 13,000 transistors, usedNMOS logic,and was fabricated in a NMOS process. By 1987, three versions of the DCT11 were available: 21-17311-01 (original 7.5 MHz version, produced by DEC), 21-17311-00 (second source, 7.5 MHz, from Synertek), and 21-17311-02 (10 MHz version, produced by DEC).[2]
A clone of the T-11 was manufactured in theSoviet Unionunder thedesignationKR1807VM1 (Russian:КР1807ВМ1).[3]
