One of the main processors used for the system is the Intel 80286, which was released in 1982. However, by the time when the TeraDrive was released in 1991, this processor was almost 10 years out of date - the more powerful 25 MHz Intel 80486 had been released in 1989, making the TeraDrive's central processor 2 generations behind its time. The system also contains a Motorola 68000 and a Zilog Z80, the same processors which were used in the Mega Drive, that ran at 7.67 MHz and 3.58 MHz respectively.
