I'll just add a note of caution for anyone doing something like this:

Updating LIST (UNCRUNCH) will affect also ASCII CSAVE/SAVE, which is 
almost certainly the correct result.

However, the read line routine used for immediate mode, INPUT, and ASCII 
program loads does strips off bit 7. That will corrupt the program when 
it is loaded back.

Obviously, the stock behaviour of the ROM also corrupts the program so 
the situation isn't really any worse.

There is another ram hook that can be intercepted to fix that.
