Sega Corporation (株式会社セガ)

A collection of technical speculations for every Sega console is listed on this page. Have fun, and dont forget that every line on each system has been triple checked for approval.

CPU:

    The Master System's CPU is a 8/16-bit Zilog Z80. The maximum addressable memory is 64 KB.

Video:

    Graphics: VDP (Video Display Processor) derived from Texas Instruments TMS9918A
        Up to 32 simultaneous colors available (one 16-color palette for sprites or background, an additional 16-color palette for background only) from a palette of 64 (can also show 64 simultaneous colors using programming tricks)
        Screen resolutions 256×192 and 256×224. PAL/SECAM also supports 256×240
        8×8 pixel characters, max 463 (due to VRAM space limitation)
        8×8 or 8×16 pixel sprites, max 64
        Horizontal, vertical, and partial screen scrolling

Audio:

    Sound: (PSG): Texas Instruments SN76489 (note that the Sega Master System, Game Gear, and Mega Drive used a slightly altered clone of the  newer SN76489A, while the older SG-series used the original SN76489)
        4 channel mono sound (3 Square Waves, 1 White noise)
        3 tone generators, 10 octaves each, 1 white noise generator
    Sound (FM): Yamaha YM2413
        Mono FM synthesis
        Switchable between 9 tone channels or 6 tone channels + 5 percussion channels
        Included as a built-in "accessory" with the Japanese Master System (1987)
        Supported by certain games only

Onboard RAM:

    Boot ROM: 64 kbit (8 KB) to 2048 kbit (256 KB), depending on built-in game
    Main RAM: 64 kbit (8 KB), can be supplemented by game cartridges
    Video RAM: 128 kbit (16 KB)
    Game Card slot (not available in the Master System II)
    Game Cartridge slot (not included on newer Brazilian models, as these have built-in games)
        Japanese and South Korean consoles used 44-pin cartridges, the same shape as SG-1000 cartridges
        All other consoles use 50-pin cartridges[25] with a wider shape
        The difference in cartridge style is a form of regional lockout
   
Expansion slot:
       
    Unused, pinout compatible with 50-pin cartridges (but opposite gender) in all regions

    Width: 365 mm
    Depth: 170 mm
    Height: 69 mm

    2 controller ports
    AV port and internal RF adapter

(Double speed), Maximum Capacity - 660 Megabytes, Audio CD play with reactive display, CD+G compatible, CD+EG compatible, CD Single compatible, Photo CD compatible, Video CD compatible and Ebook compatible
   

Intel Pentium E2160 CPU @ 1.8 GHz

1GB of DDR2 PC2-6400 RAM

An “nVidia GPU” w/ 384MB of GDDR3 RAM and supports Shader Model 4.0 and “two 1920×1200″ which probably means it has ports for two monitors and can support up to that resolution. Also as of a note, it says “nVidia GPU 2″ on the document up higher – not sure if that means

5.1 ch HD Audio

Onboard Gigabit LAN

A 32GB SSD drive for storage (finally, flash storage instead of a standard HDD which will likely fail soon)
