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.
