This is a demo that can run on the ATM Turbo 2 . It was made by Alone Coder in 2023 and you can download it here:
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 and a new version called ATM Turbo 2 were introduced.
ATM 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.
GRAPHICS MODES:
For compatibility purposes, the original 256 x 192 ZX Spectrum mode is available.
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).
