 Re: A mathematical demo

If BBC Micro would use Plus/4 double frequency idea then it would be 50% faster. C128 may use double frequency at the vertical borders by raster interrupts and this gives average 1.3 MHz for CPU in the VIC mode.
IMHO the best way to speed up Plus/4 is to quadruple CPU clock at the borders...
