[edit] Technical specifications

Arcade machine consists of several boards called BEIA (Russian:БЭИА, Блок Элементов Игрового Автомата, Blok Elementov Igrovogo Automata). The boards have the following purposes:

BEIA-100: data processing; RGB DAC; sound generation; coin-op and game controller interface
BEIA-101: video sync and background generation
BEIA-102: sprite generation
BEIA-103: game ROM and main RAM

Games in a TIA-MC-1 arcade machine can be switched by replacing BEIA-103 module, not unlike cartridges in video game consoles.

Main system characteristics are as follows:

CPU: КР580ВМ80А (clone of Intel 8080), 1.78 MHz
Video resolution: 256×256, 4 bits per pixel selectable from a palette of 256 colors
- Background: two video pages comprised of 32×32 tiles, each tile is 8×8 pixels. Tile RAM can store 256 separate tiles.
- Sprites: up to 16 simultaneously displayed hardware-generated sprites; total of 256 sprites can be stored in sprite ROM. Sprites can be vertically and horizontally mirrored in hardware.
Sound: two КР580ВИ53 interval timers (Intel 8253) driving a mono speaker.
Display: 20” TV screen
Main RAM — 8KiB.
Character RAM — 8KiB.
Video RAM — 2KiB.
Sprite ROM — 32KiB.
ROM with game code and background graphics — up to 56KiB.

[edit] Emulation

For a long time TIA-MC-1 hardware remained unemulated due to lack of technical information and ROM dumps. Soon after the Russian emulation community obtained technical documentation and ROM dumps of one of the games, Konek-Gorbunok, the first emulator named TIA-MC Emulator was released on July 27, 2006. A TIA-MC-1 driver was included in MAME on August 21, 2006 (since version 0.108). By now, only one game is supported. An ongoing search for other games is in progress.
