These were 32-bit minicomputers from Fujitsu and Panafacom (currently PFU). In April 1987, Fujitsu announced 7 models in the FACOM A (Ace) Series and Panafacom announced 7 models in the PANAFACOM A Series. These machines were designed to support the open culture, improve price performance and expand performance range. The two series were different only in brand name, and were the exact same product. This A series combined two previous series (the PANAFACOM U-1000 Series and FACOM/PANAFACOM S-3000 Series) into a single series under an OS for the UNIX community. The series was comprised of 7 models ranging from the bottom-end A-30 model to the top-end A-600 (i.e. the A-30, A-50, A-70, A-300, A-400, A-500 and A-600). The full lineup had a performance range of about 40 times (in terms of the scientific/engineering calculation ratio) to provide highly-scalable support for expansion and diversification of application. This A Series was divided into two groups: the Compact A (Ace) which focused on greater compactness and lower price, and the Super A (Ace) which focused on performance.
