Probably... want to try it out with "assign cf_power = 1;"?

I'm going to release version 11 of the ABC80 project as soon as it 
finishes doing a clean synthesis, and include a new CF card image.  The 
CF card image has programs to set the character set to Swedish/Finnish 
(default), Danish/Norwegian, or "international" (US).  The cool part is 
I actually wrote the card on the ABC80; just uploaded the files with 
TERM100 (terminal program), which -- much to my surprise -- worked right 
out of the box, and -- even more surprising -- without being dependent 
on CPU speed.  I'm guessing it's using the 128 µs interrupt to do its thing.
