Mordaunt short decoder one (dolby pro logic)

Hello and welcome to my auction for my Mordaunt short Decoder ONE!!! Very very RARE!!! It is one of the very first Cinema sound decoders that became available to the public during the 1980's. I predict that I bought this second hand around 1993. As a teenage sound enthusiast I couldnt afford a brand new cinema system so I built my own from speakers I borrowed from family, but I did actually pay for the Mordaunt short decoder!! It has enough amplification to power 2 surround speakers and 1 centre speaker. It requires coupling up to a power amp, for the front speakers and Subwoofer. It has 2 RCA inputs, and Four RCA outputs. You can either select 2 way operation, or full cinema dolby surround sound. When I was young I built a wood cabinet to house all my components, but being young, I only measured the front of the unit and forgot to include the extra height of the rubber feet, so these were removed to fit snugly in my cabinet. I havent used it for 13 or so years, but it switches on just fine, and all the buttons and knobs work fine. I will connect it up to a sound source and speakers if asked. There are some scratches and scuffs, and also some signs of corrosion as if a battery has leaked on the case, but this hasn't affected the operation, just the paintwork. I have searched Google for some tech specs but I cant find anything, as it doesn't have a manual. I am open to questions, and can send further photos if required.
