MoG v1.04 activates Turbo CPU on turboR but seems to have a problem on other machines like CIEL and Panasonic. I haven't actually tried with CIEL ExpertTurbo but the code I wrote below is in the ROM file of MOG 1.04 and was tested on FS-A1WSX with openMSX. If you turn it into a .COM file it is fine but when you start MOG 1.04 it is not applied. The routine was also confirmed with 1chipMSX supporting ID 8 on port 0x41.

0xDB, 0xB6, 0x3E, 0x08, 0xD3, 0x40, 0xDB, 0x40, 0x2F, 0xFE, 0x08, 0x20, 0x05, 0xAF, 0xD3, 0x41, 0x18, 0x0C, 0x3A, 0x80, 0x01, 0xFE, 0xC3, 0x20, 0x05, 0x3E, 0x82, 0xCD, 0x80, 0x01, 0xC9
