Libra Logic Ltd – a Wokingham, Berkshire systems and software company – has launched Liberator, an intelligent network controller. It allows multiple combinations of industry standard computers and terminals to be linked together, enabling users combine the most powerful host computer with the least expensive industry standard terminals. The developers claim that because the system is software-based it is genuinely open-ended, and can offer a wide range of management facilities. The Liberator is a programmable device which acts as virtual host or virtual terminal in a system. It employs open architecture based on an intelligent bus. Acting as a data switch it routes data between independent subsystems, providing connectivity and management facilities for up to 48 ports. These independent subsystems provide primary links including X25/SNA at up to 64Kbps for wide area network connections, and Ethernet for local nets. The device can be supplied with a high speed memory of up to 4Mb and permanent storage of up to 40Mb can also be incorporated in floppy or hard disk. The device, which has a starting price of UKP3,000, has been in production for six months and 150 have been sold to date.
