The ATM Turbo (ru: "АТМ-ТУРБО"), also known simply as ATM (from ru: "Ассоциация Творческой Молодёжи", meaning "Association of Creative Youth") is a ZX Spectrum clone, developed in Moscow in 1991,[1] by two firms, MicroArt[2] and ATM.

It offers enhanced characteristics, compared to the original Spectrum, such as a Z80 at 7 MHz, 1024 kB RAM, 128 kB ROM, AY-8910 (two chips in upgraded models), 8-bit DAC, 8-bit 8-channel ADC, RS-232, parallel port, Beta Disk Interface, IDE interface, AT/XT keyboard, text mode (80x25, 16 colours, 8x8 pattern), and three new graphics modes.

The ATM can be emulated in Unreal Speccy v0.27 and higher.[3]

History

[edit]

ATM was developed in 1991 based on the Pentagon, a ZX Spectrum clone popular in Russia. In 1992 an upgraded model was introduced, named ATM Turbo 2.[1] Up to 1994 the computer was produced by ATM and MicroArt; later the firms separated and production ended.

In 2004 NedoPC from Moscow resumed production.[4] New versions called ATM Turbo 2+ and ZX Evolution were introduced.[5]

Characteristics

[edit]

Graphics modes

[edit]

For compatibility purposes, the original 256 x 192 ZX Spectrum mode is available.

New graphics modes offer expanded abilities:

  • 640 x 200 mode, with 2 out of 16 colors per 8x1 pixels. The Profi offers a similar mode, but the ATM can use the full 16 colour set for both ink and paper.
  • 320 x 200 mode with a 16 colours raster mode (a two-pixel chunky mode, not planar like EGA). Two games for this mode were converted directly from PC: Prince of Persia[6] and Goblins,[7] and one from Sony PlayStation: Time Gal.[8] Other games that use this mode exist, like Ball Quest, released in August, 2006.[9]

Operating systems

48K Sinclair BASIC, 128K Sinclair BASIC, TR-DOS, CP/M, iS-DOS, TASiS, DNA OS, Mr Gluk Reset Service.

Models

[edit]

Many models exist. Models before version 6.00 are called ATM 1, later models are called ATM 2(2+) or ATM Turbo 2(2+) or simply Turbo 2+. An IDE interface is available since v6.00.JIO0UBH9BY8B9T7GVC6R (the latest model is 7.18[12][1]).
