TNS-NET 900
Network for TNS HC-16, TNS XT and TNS at, successor TNS-Net. According to English terminology, it will probably be a plagiarism of some western product, according to the catalog org. The 1989 practitioner is RPTI ("RPTI-LAN", but it could be "RPTI trans-Net").
Each station has its number, this number can be in the range of 0 to 254. There must be no more stations with the same number in the network. On TNS-LAN AT I TNS HC-16 are chosen using 8 switches
- Transfer speed: 888 kbit/s
- Manchester coding
- Network impedance: 50 Ohm (galvanic ward)
The development of hardware for the TNS-Net 900 and the FELAN card took place in the Tesla Elv.
Tree topology, coaxial cable 50 Ohm max 500m, CSMA/CD, speed 900kbit/s, Manchester coding, total max. 32 knots.
For TNS-at there was a TNS-LAN-At-At Intel P8274 (Multi-ProtoCol Serial Controller, implemented by SDLC), as well as the "network card" in the TNS HC-16.
Content of distribution floppy disk
The floppy disk that is uploaded to the TNS-MET 900 sotfware network contains the following files:
- Attn.exe Program for sending reports to network participants.
- Compool.com The program will redirect data from parallel to a serial port.
- Connect.exe program to connect a shared remote directory or printer.
- FSVr.EXE program installing station as File-Server.
- GetTimer.exe program that sets the date and time to time-server in the network.
- Instimer.exe program installing station like time-server.
- Net.exe program starting the main menu of the network.
- Netfile.exe program for closing open films at File-Server.
- Netsave.exe program for saving network configuration.

Minimal hardware prerequisites for each sensation in the TNS-Net network are
- 128 KR internal RAM (256 kB for computer without disks (Diskless Station) using remote introduction of operating system).
- At least one disk or autoboot ROM for remote introduction of the operating system.
- If the network is used by Autoboot ROM, the network must work boot-server.
Program prerequisites for TNS-Net network functioning are:
- MS-DOS/PC-DOS version 3.1 and higher
- Network operating system TNS-NON.
