Janus/Ada implementation of a star cluster network of personal computers with interface to an EHTERNET LAN allowing access to DDN resources
janusadaimplemen00hart.pdf (14.24Mb)Abstract
This thesis demonstrates the viability of implementing
a local area network connecting a star cluster of Z-100
personal computers to an ETHERNET local area network and
allowing access to a wide area network, ARPANET, through a
host on ETHERNET, the VAX 11-780 minicomputer operating
under UNIX. The system allows local file and message
transfer in port-to-port and broadcast mode between Z-100's
on the star network and remote login and file transfer to
computers that are hosts on ETHERNET or are accessible
through ARPANET. The microcomputers in the cluster can
share expensive resources such as laser printers, the
Gemini multi-level secure system, the ETHERNET medium, and
the network control processor.
Components of the system are programmed in the
Janus/Ada programming language for both the Z-100
microcomputers and the Intel 86/12A single board computer.
