This is wrong!

You get ~30K for basic USING THE STANDARD BASIC as used on  
a standard machine.

HIBASIC gives 44K (or there abouts).

The "TUBE" rom is generally known as the DNFS. (DFS1.2) The  
tube code tagged into this rom, and just keeps itself quiet  
unless it sees a co-pro.

Without the DNFS it is pretty useless. However thats pretty  
easy to track down.

HIBASIC is a handy addition, but not really esential. Loads  
of other programs (particularly ROMS) can make use of the  
extra space, and speed. (ISO Pascal on a 6502 co-pro is  
totally awesome - if you're into running pascal on 8bit  
machines :-)).
