Gyrosystem ported OSI layers 1, 2 & 3 of an existing X.25 communications software package to run on Motorola's MVME334 card. 

The software was written in 'C' & 68030 assembler and developed on a UNIX Workstation. 

PSOS was utilised as the Real-Time Operating System providing task and event management services. 

A study was conducted to determine whether utilisation of the MVME334 cards' X.25 protocol controller would improve performance and simplify the software for the Physical and Data-Link layers.
