Thanks to everyone for their replies. I will have chance to try a few 
things over the weekend and will report back next week with any progress.

I did have various ideas, including having an eprom burner but I do not 
have the rom for it any more :( otherwise I would of popped the DFS rom 
into that to see what state it was in) , and I am unable to find the 
correct one (there appear to be variations) but that discussion is 
probably better on another thread at some point in the future, or using 
econet to get the program there (but that machine has some faults)

I really must sort my machines out as I have another one with worn out 
(not by me) rom sockets and another with other annoying minor problems. 
I must contact someone at some point to have a few replacements fitted I 
think.

Jonathan, yes they are missing sadly :( , I know what you mean though 
and understand why you asked. As if my memory serves me correctly there 
are two unused ones (one each side) , but there are too many missing and 
there was one present and bent (it broke when I carefully straightened 
it, despite straightening many a bent rom pin without damage) , hence me 
temporarily using some small lengths of wire and a parts of a broken 
turned pin socket (to act as "pins") , I planned to have a replacement 
fitted if it functioned.
