The promised co-processor implementation of Unix for ICL’s best selling low-end processor, the System 25, has finally arrived and ICL is hinting vaguely at a native Unix for the machine. The aim of the 68020 co-processor option is to broaden the range of applications available for existing System 25 users. The 68020 co-processor runs Unisoft’s port of UniPlus+ V.2, the existing processor runs ICL’s proprietary DMF III operating system. Files and peripherals can be shared by the two operating systems but a program running under Unix cannot invoke one under DMF III. An introductory Unix offer is available from ICL to existing System 25 users: an upgrade kit costs UKP5,500 for the board, operating system and an RS232 port. Additionally ICL is offering special discounts on 120Mb, and 40Mb disk drives and 320Kb storage if these are ordered with the Unix upgrade.
