ANB22 BBC Econet Upgrade parts
The BBC Micro motherboard (Model A, B, B+, B+128k and ABC computer) has an unpopulated bit on the motherboard in the back left (looking from the front) where the Econet interface is installed. It is fitted as standard to the US and German BBC Micros. This is the upgrade pack, the one I have comes in a padded bag (top picture). In the bag contains the Econet level 1 File Server User Guide , the Econet Level 2 File Server User Guide and the Econet Advanced User Guide (middle picture). The upgrade itself consists of a packet of resistors, some ICs, a socket and the cable (bottom picture). Some soldering skill is required to install it!
The upgrade includes an NFS ROM to fit in one of the Sideways ROM sockets. Later the DFS and NFS ROMs were combined in the DNFS ROM which contained DFS v1.20 and NFS v3.60. The DNFS instruction booklet describes the installation and features of the DNFS ROM,
