Hi BASIC *one*? Well, that's a turn-up for the books. That will definitely
be some sort of development version, just standard BASIC 1 assembled at
&B800 instead of &8000. BASIC 1 was very quickly replaced with BASIC 2 
as it had various bugs and omissions. All Hi BASICs that were supplied 
with the 6502 second processor for the BBC were either BASIC 2 or BASIC 3.
