Changes
/* Turbo Mode Upgrade */
Runs the CPU at faster speed. Intended for programs that require a lot of CPU load, like compilers, or ported MSX games (which need to draw the MSX video display processors (VDP) hardware sprites by software).
* The Turbo Mode schematic is unknown
* Turbo Mode is said to be incompatible with AMSDOS disk access for timing reasons (ie. works only with MSXDOS or so) (not sure if that's a bios/software related problem - it might also be caused by video resolution(which changes CPU and DOT clocks): working in 256/512 pix modes, but not in amstrad-style 160/320/640 pix modes)
