Well,
Things are now going on a pace.  I have got a 1.1A running nicely on the 3400.
It appears that all problems over tape copying were due to funnies within
the copying process, don't ask me what, I never solved them and resorted
to buying a DEQUNA and netting the stuff over.

So, I am now going to get all of the sources over and start looking at 
playing with the code.  When it gets to looking at 1.2, will there be a 
patch kit for 1.1 -> 1.2 or do I have to start again?.

Cheers and thanks for all of the advice and help.

Robin
