OK just built the PCB up and it works - had one fault that 'e' the Column for 3 and D did not work - I had to flow a lot of solder through the hole so maybe a board fault - something to watch out for but, easy to find with key14 trying various keys!
The connector I had did not have the top pin to wire through Ground though so no reset available. But make a neat job I think with no need for flying leads - no use on the Triton or the JMP board but, suits me for this specific use.
