Set screen on turbo-r GT

Indeed. On the bottom of your turboR you can find a cover under which the batteries that keep the clockchip data can be found. Replace them with ordinary (or rechargeable) penlites and you should be set for a couple of years

Yeah, 2x AA battery, IIRC.

BTW I just noticed, that you can restore the default values by holding ESC down at startup.

By the way, I do not know what happened, but I cannot get that nice big kanji font MSX-DOS mode. Is that related to the fact of having a CF-IDE adapter working?

Is it possible to set it using the SET SCREEN procedure? I am afraid that I do not understand my Turbo-R GT! That is why I am still using my old SANYO MPC-100.

I think that was changed in either MSXDOS2.SYS or some odd setting in the AUTOEXEC.BAT file. Check the DOS2 disks that came with your Turbo-R, at least one of 'em boots in Kanji mode. I for one liked the 'small' kanji a lot better tho, kanji mode 3 if I remember correctly...
