* The main processor was the venerable (and, in 1983, still quite formidable) Zilog Z80, running at 4 MHz. The ADAM added several Motorola 6801s for running the keyboard, printer and tape drives. |

** Sega's SG-1000, the ancestor of both the Master System and Genesis, was virtually identical to the Colecovision, to the extent that at least one clone console could play both Colecovision and SG-1000 cartridges. |

Memory= |

* The main CPU was somewhat starved of RAM unless you had ADAM, but both systems had a very generous 16K of dedicated VRAM, making them two of the most powerful consoles of their time. |

* ADAM itself had a full complement of 64K, as well as two different operating systems in ROM. (Or one OS and a word processor.) |

Sound= |

* Used a TI three-channel programmable sound generator, the same as in TI's own machines and the IBM PCjr, and similar in capabilities to the GI/Microchip AY-3-89xx used by the Intellivision and MSX. |
