Sudbury, Massachusetts-based Bell Atlantic Software Systems Inc is offering Digital Equipment Corp DECnet support software for Unix systems, and its first taker is Ing C Olivetti & Co SpA, which launched it on Monday (CI No 1,686 and page two inside). The company reckons it is the first third-party vendor to develop and market a DEC-certified version of the network protocol. Bell Atlantic will license its Access for DECnet, to Unix providers. It will be available for hardware and software suppliers in the third quarter on a source licence basis. No word on the price.
