which Olivetti computer had 8" drives?

It had a CDC external drive with 1 fixed disk and 1 removable 10MB cartridge. Don't recall the size but I guess 14". No floppy, tape or other drives. The machine itself was approx 1m wide, 1m high and 0.5m deep and was based around a Z80 with an 8080 coprocessor. 192K total RAM IIRC - guess some sort of paging system was used. The terminal was olivetti too with a very nice blue phosphor screen. Ran something called BOSS "British Olivetti System Supervisor" and wasn't terribly interesting. Also had an RS232 connected dot matrix printer which outlived the system by several years. Anybody else know anything more about these systems? James
