SuperVozelj - packet radio node computer


SuperVozelj is replacement for TheNet digipiters.

Supervozelj was developed by Matjaz, S53MV. There was too much trouble with 10 MHz TNC-2 running medium-speed packet (19200 and 38400), and no cheap solution is available.

SuperVozelj nodes are home made 68010 computers with three SCC chips, giving 6 channels. Each node has remote HW reset, and SW can be uploaded over the air. Software is written in 68k ASM. Current version 69 is some 16 kbytes long. Most of work is focused on AX.25 drivers, memory management, stable structure, and routing is similar to KA node or SP, just to give functionality to the users. It keeps track of activity, so most stations can be connected simply by C CALL from any node. Several nodes have TheNET node attached to free port, and they can be used as well: this is for compatibility with existing TheNET nodes. Some BBSes are connected directly to SV node using KISS protocol.
