The Atari TT030 was intended to be a high-end UNIX workstation, but delays in releasing a port of Unix SVR4 meant it was never a success in this market. It was replaced in 1992 by the Atari Falcon, a lower cost machine more oriented towards home consumers.
The Atari TT was one of the first non-Intel machines to have Linux ported to it, along with the Atari Falcon and Amiga. NetBSD was also ported in 1995.
The main CPU was a Motorola 68030, clocked at 32MHz supported by a 68882 floating-point unit. Backward compatibility with existing ST peripherals, as well as use of existing ST chips meant that the system bus ran at half the speed of the CPU (16MHz). A variety of off-the-shelf and custom logic chips provided the bitmapped graphics, DMA, SCSI, floppy, and serial interfaces.
The Atari TT had several features it's predecessor (the Atari Mega STE) did not: a SCSI port, VME expansion bus, new VGA graphics modes, and an Appletalk network port (although drivers for this were not provided). It retained compatibility with existing ST features such as MIDI ports and the ASCI/DMA port.
