Just taken the plunge and bought me the above machine. My ignorance let me think it was ok as everything seemed to work when shown it. However the seller was a bit shady by (it appears) having the top resting down and not shut down thus having it in fre play mode. Once i got it home and powered it up it displays an invalid key error and door 79 error.
I could surely use any help any of you may be able to give me

The machine appears to be in good nick really and came with all keys and percentage keys.
Look forward to your replies
