If you are struggling I am sure Ian on the FB group would burn you one. It is possible that Sirius has a programmer that can do them as well for a UK source - he is a very helpful chap like that.

Thanks Guys I have now found my PROM (IC70 ), I have read it and it is the same as the bin file (IC70.BIN) Timbucus uploaded here so I should be good to go.
I have also found the Original Transformer 8.5, 12-0-12 volts this I believe this was custom made for the Triton and is hard to come by now.
There is a photo here
https://sites.google.com/view/transa.../photo-gallery its looking a bit old the 8.5 volts is unusual but I understand this was done to keep the heat generated by the linear voltage regulator (IC1 LM323K) down.
But I do seam to remember this did get quite hot which is why I added the external switch mode power supply.
