Ian Wolstenholme describes the BeebMaster Econet Module (slightly edited) as:
In possibly the first full Acorn 8-bit related manufacturing project of the twenty-first century, the BeebMaster Econet Module is a high-quality alternative to the hard-to-find Acorn Econet module. Made and assembled in the U.K., the BeebMaster Econet Module plugs into the sockets provided on the motherboard of the BBC Master and later machines.
These Econet Modules have been specially produced for BeebMaster. They are suitable for the BBC Master 128, Master Compact, Acorn FileStore and practically all the 32-bit Acorn range including the A305, A310, A410, A420, A440, A540, A3000, A3020, A4000 and A5000.
The module is supplied with ANFS 4.25 ROM for use on the BBC Master 128.
I do not have a BeebMaster Econet Module.
The BeebMaster Econet Module is suitable for the BBC Master and many of the Archimedes range,
