Honeywell Bull Italia yesterday announced support for the SPIX implementation of Unix System V for the DPS 4000 small business computer – but like ICL with System 25, it has decided to do it by means of a co-processor. The DPS 4000 has a modular multi-processor bus architecture, facilitating support for co-processors alongside the GCOS 4 operating system, and SPIX 4 runs on a 20MHz 68020 with 68881 and 4Mb.
