I took the liberty of making some small adjustments (mainly using a custom 
character set in 16x8 mode so we can clear the sceen by just writing zeroes 
everywhere)

The following will do a full-frame cycle through all colors on PAL - only the 
bottom two lines will be black. I tested this on a real VC-20 with analog 
monitor (with h size and v size adjusted so the entire frame is visible) - also 
verified that the border color is never displayed, apart from on the bottom 
lines by changing the 8 in line 135 to 9.

Cheers
