The main product of the ACE group is the Advanced RISC Computing specification, or ARC. It was initially based on MIPS-based computer hardware and firmware environment. Although ACE went defunct, and no computer was ever manufactured which fully complied with the ARC standard, the ARC system still exerts a widespread legacy in that all Microsoft Windows NT-based operating systems (such as Windows XP) used ARC conventions for naming boot devices before Windows Vista. Further, SGI used a modified version of the ARC firmware (which it calls ARCS) in its systems. All SGI computers which run IRIX 6.1 or later (such as the Indy, Octane, etc.) boot from an ARCS console (which uses the same drive naming conventions as Windows, accordingly).
In addition, most of the various RISC-based computers designed to run Windows NT used versions of the ARC boot console to boot NT. Among these computers were:
- MIPS R4000-based systems such as the MIPS Magnum workstation
- all Alpha-based machines with a PCI bus designed prior to the end of support for Windows NT Alpha in September 1999 (the Alpha ARC firmware was also known as AlphaBIOS)
- most Windows NT-capable PowerPC computers (such as the IBM RS/6000 40P).
It was also predicted that Intel IA-32-based computers would adopt the ARC console, although only SGI ever marketed such IA-32-based machines with ARC firmware (namely, the SGI Visual Workstation series, which went on sale in 1999).
