Like its little brothers Goupil and Goupil 2, the Goupil 3 is based on a back-plane architecture. You get the computer you want by adding different electronic boards. Thus Goupil 3 can be a tri-processor system: Motorola 6809 like its little brothers, Zilog Z80 for CP/M compatibility and Intel 8088 to match the emerging "IBM PC/MS-DOS" movement. The processors don't work simultaneously but can use a time sharing mechanism.
Like the Goupil 2, the Goupil 3 was especially designed for communication, and thus had a built-in modem. Among other things it can emulate the Minitel (French videotext terminal) or connect to data centers.
The 5.25" floppy disk drive can be replaced with an 8" drive (1.2 MB). A 10 MB hard disk was also available as an option.
The Goupil 3 can run under a lot of operating systems: Flex 9 or Uniflex (with the 6809), CP/M (with the Z80) or CP/M 86 or MS-DOS with the 8088.
