Summary: MSX Turbo-R secondary bus seems to be hardcoded at 3.57MHz

Initial Comment:

While the R800 is being used, the secondary bus of the MSX Turbo-R seems to be hardcoded at 3.57MHz, instead of being at the same speed as the Z80A (defined by set Z80_freq and z80_freq_lock commands).

But when the Z80A is being used, the secondary bus is running correctly at the same clock the Z80A is. The front side bus of the MSX Turbo-R also seems to be running correctly at the same speed as the R800.

The secondary bus of the MSX Turbo-R is the bus that contains the MSX-Engine, the ROMs, the VDP, the YM2413 and the slots.

The front side bus of the MSX Turbo-R contains only the R800 and the system memory.
