26 clocks in a border, anything useful?

If you had 26 clocks in the border, could anything useful be done with the extra clocks? If you need to do a XXXX,X this could be dropped to XX,X to save an extra clock.

in 26 you can make rasterbars, is that usefule for you ?

btw:

sta xxxx,x = 5 sta xx,x = 4
lda xxxx,x = 4/5 lda xx,x = 4

you could perhaps put an extra clock in the border!

C128, you can enable 2Mhz mode in the border. So when you subtract the clocks to get in and out of 2Mhz mode you get 26 clocks to do stuff. Or if you drop the 38 col you would get 30 clocks.

you might be able to cram a sample player in there.... the question is a bit generic though, hard to give an answer without knowing what else you are planning to do :)

Make some double, triple sine table lookups for your excellent dynamic raster based effect... whichever it is.
