Radius Plc yesterday announced an agreement with the value-added reseller division of British Olivetti Ltd for joint marketing of the Radius Distribution and Warehousing products, Dawn, on the Olivetti AT&T 3B2 range of Unix processors. This came as Radius released its interim results for the half year to May 31, and reflected what is said to be considerable development of solutions being offered on Unix. Orders for the second half of the year are reported to be at record level and include several large Unix based projects. Radius also says it has the potential to be the first major software house in the UK to offer applications under Unix on the Data General range. A deal with ICL is in the offing but it declined to comment.
