Fast Math ROM
I remember there used to be a replacement ROM from a thrid party for the 400/800 Floating Point ROM. Anyone know the name? How did it work? Did it just replace the BCD math routines with binary ones? How much faster was it? Anyone have a copy now?
Installing the Charles Marslett FP routines in ROM makes, IIRC, Turbo BASIC XL 1.5 work incorrectly. To be precise, math functions like LOG, CLOG and raise to power start to fail. It seems then, that Turbo BASIC XL uses some ROM code
