Future Product Announcement: NetDOS, a Z-System SCSI LAN. Do you have more than one Z-System? Wish your Z-Systems could share files without swapping floppies or connecting RS-232 ports? ...then NetDOS is for you! NetDOS will provide file sharing between any Z-System SCSI equipped computers. Ampro host adapters may be used to provide a SCSI bus to an existing Z-System. NetDOS will require NZCOM and knowledge of SCSI port addresses, ... for the latest information, become a NetDOS Supporter. NetDOS Requirements and Features: OVERVIEW: NetDOS is a network operating system that will allow Z-Systems to share files, and perhaps in a future version to perform multi-processing. Basically, a user's system will appear to be a CP/M compatible OS, in particular a ZCPR3.4 CCP and a modified ZRDOS. The network will be achieved thru the use of the SCSI 8-bit parallel bus, therfore all Z-Systems wishing to connect must have a SCSI bus, in particular this is an arbitrating SCSI with all computers capable of being both initiator and target. Consult a SCSI reference for further information, Adaptec controller card manuals are excellent. Since standard SCSI is limited to 8 devices, initially NetDOS will be a cluster of 8 SCSI devices, probably 1 hard disk controller card and 7 computers. Ampro has defined an extension that allows additional devices, and should the need arise an extnsion should be possible. One computer needs to be designated as the mass storage controller, commonly referred to as the file server. This requirement is necessary to prevent file overwriting caused by multiple disk allocation vectors existing on different computers. All files controlled by the server are available to the networked computers. All such global files are available with read permission, even when opened by another user computer. The first system to access a file also will have write permisssion. Accessing global storage will 'appear' to be indentical as accessing local storage to most programs, exceptions are programs in the DU category which can only be run from the file server itself. REQUIREMENTS: NZCOM - to load the various NetDOS segments, thus it's for Z80 processors and equivalents. SCSI - arbritrating, initiator and target. Note that the SCSI length limitation of 6 meters is unimportant if you use RS-232 terminals, as RS-232 cables can be run for very long distances. FEATURES: Storage - local or global. Devices - devices connected to the server can be global, i.e. a printer or modem. Welcome to X-Node (The Experimentors Node { XN }), Home of NetDOS. NetDOS is a trademark of Non-Linear Thinkers. NetDOS Supporters will be entitled to purchase any final product for $90, otherwise the price will be $120. No refunds of Supporter funds will be made if the project fails due to unforseen technical difficulties, i.e. a Supporter is an invester in the project and assumes all usual risks.

Additionally, Supporters will be able to run NetDOS immediately at release if they have followed the NETDOS: information files. As a side effect, Supporters will have permanent access to XN and not be subject to the 60 inactivity loss of access rule. To become a $upporter, send $10 and a SASE to: R.
