As of 2020[update], only one box is available, the ABox, that lets users run extant AmigaOS software compiled for Motorola 68000 series (MC680x0 or 68k) and PowerPC central processing units (CPUs).
Quark also has an asynchronous/synchronous message interface similar to Amiga's Exec kernel but adapted to an environment with memory protection.
[4][5][6] Trance was developed by Ralph Schmidt and Teemu Suikki, with minor support from other MorphOS team members, Mark Olsen, Sigbjørn Skjæret, and Harry Sintonen.
Under the Quark kernel, a PowerPC native reimplementation of the OS known from the Commodore International A1000, A500(+), A600, A2000, A1200, A3000(T), and A4000(T) systems runs as a mix of a virtual emulation and a driver.
The 68k emulation is written in C and uses GNU Compiler Collection (GCC) assembly language macros where needed to speed up some complex instructions.
