ATM (computer)


The ATM Turbo, also known simply as ATM is a ZX Spectrum clone, developed in Moscow in 1991, by two firms, MicroArt and ATM.
It offers enhanced characteristics, compared to the original Spectrum, such as a, RAM, ROM, AY-8910, 8-bit DAC, 8-bit 8-channel ADC, RS-232, parallel port, Beta Disk Interface, IDE interface, AT/XT keyboard, text mode, and three new graphics modes.
The ATM can be emulated in Unreal Speccy v0.27 and higher.

History

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. 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. New versions called ATM Turbo 2+ and ZX Evolution were introduced.

Characteristics

Graphics modes

For compatibility purposes, the original ' ZX Spectrum mode is available.
New graphics modes offer expanded abilities:
  • ' mode, with 2 out of 16 colors per 8x1 pixels. The Profi offers a similar mode, but the ATM can use the full set for both ink and paper.
  • mode with a raster mode. Two games for this mode were converted directly from PC: Prince of Persia and Goblins, and one from Sony PlayStation: Time Gal. Other games that use this mode exist, like Ball Quest, released in August, 2006.
Palette:
48K Sinclair BASIC, 128K Sinclair BASIC, TR-DOS, CP/M, iS-DOS, TASiS, DNA OS, Mr Gluk Reset Service.
