The Atari Falcon 030 is the successor of the Atari 520 STe and the Atari TT 30.
It keeps some features these machines : The graphic modes (320 x 200 / 16 colors, 640 x 200 / 4 colors, 640 x 400 / 2 colors, 320 x 480 / 256 colors and 640 x 480 / 16 colors) and the sound chips (the old Yamaha PSG and the two 8 bits PCM channels of the STe).
Two new graphic modes have been added : a "small" 256 colors SVGA (640 x 480) and a true color VGA mode (32768 / 65535 colors in 320 x 480). Also when running on a TV, the resolutions are different: True Color mode is 640x480 in PAL and 640x400 in NTSC. The other TV resolutions also have a difference of vertical resolution between PAL and NTSC: 200 or 400 lines in NTSC, 240 or 480 in PAL.
New interfaces were added too : an ADC 16bit 50 KHz and a DSP I/O port. The videochip has also genlocking features.
The Falcon was sold with the single-task TOS operating system in ROM (4.04). It is the old Atari ST TOS with new functions to handle the DSP and the new graphic modes. The GUI was slightly enhanced with colored icons and 3D windows.
Hopefully a multi-task TOS - MultiTOS) was also delivered on disks. This multitasking system uses the MiNT kernel and an enhanced GUI. MiNT (which stands for MiNT is NOT TOS) is a multitasking Operating System with lot of Unix features. It was initially done by Eric Smith. It was bought later by Atari and became then "MiNT is NOW TOS). Atari planned first to put it in ROM, but it was not finished and was shipped on disks.
