All models supported, including the Medusa clone. The following Atari models (or clones) have the "right" processor built-in: Atari Falcon, Atari Falcon with Afterburner 040, Atari TT, and Medusa. However, the standard Falcon does not have an FPU built-in (so you will need to add an FPU). Accelerators are available for all Ataris that will upgrade the CPU to an acceptable level; see the section called Processor for the CPU/MMU/FPU combinations currently supported by Linux/m68k.
Note that in some of the older Atari TTs there is a bug in the PAL controlling the access to the FPU. This may cause crashes (see the section called TT-FPU bug in Chapter 6).
Supported built-in hardware:
All serial ports (including the MIDI port)
