Introduction

The Master ET is an Econet Terminal. It is missing most of the ports on a Master 128. It only has Econet, RGB and Comp Video ports at the back and no connectors underneath. Unlike the other Masters, the Master ET does not have any applications in ROM (i.e. View, ViewSheet, Edit and Terminal). These omissions reduced the cost of the Master ET to £399 (inc VAT).

Master ET

I had never heard of the Master ET until I saw one when collecting my Domesday System. So I bought it out of curiosity.
 
Here are some photographs:

On the right hand side there is only 1 ROM in the sideways ROM sockets. Along the front all the interfaces are missing. Finally note the number of uninstalled components on the board.
