ATM (computer)

ATM (ATM Turbo) is a ZX Spectrum clone, developed in Moscow, in 1991, by two firms, MicroArt and ATM. It has Z80 at 7 MHz, 1024k RAM, 128k ROM, AY-8910 (two ones in upgraded models), 8-bit DAC, 8-bit 8-channel ADC, RS-232, Centronics, Beta Disk Interface, IDE interface, AT/XT keyboard, text mode (80x25, 16 colors, 8x8 pattern), and 3 graphics modes.

Graphics modes

640x200 mode has colour attribute byte for each 8 pixels. Difference from Profi is that ATM has full 16 colour set for both ink and paper.

320x200 mode (16 colours) is ordinary raster mode, but not similar to EGA (it is two-pixel chunky, not planar like EGA). Two games for this mode were converted directly from PC: Prince of Persia and Goblins , and one from Sony PlayStation: Time Gal. Some other games for this mode exist. The latter one is Ball Quest (August, 2006).

256x192 ZX Spectrum mode.

Palette (16 colours from 64) is set for all modes.

Models

Many models exist, the recent is 7.10 (with some bug fixes by NedoPC). Models < v6.00 are called ATM 1, later models are called ATM 2(2+) or ATM Turbo 2(2+) or simply Turbo 2+. IDE is available since v6.00.
