Hi Mike,

the 2nd processor is initialising - I get the "Acorn TUBE 6502 64K" message.

I saved my DFS 1.2 rom to disc and *DUMPed it, part of the header reads 
'DFS,NET'.

Is it possible that HiBasic doesnt work because I'm loading it into one of 
the sideways ram banks on the solidisk 2meg 128?

Thanks for your help,

Julian.
