Hi folks, like many of you, I recently purchased a cheap new old stock Toshiba HX-MU900 MSX audio cartridge with HX-MU901 piano keyboard. I now want to upgrade it with 256KB of sample ram and a new MSX audio bios. There is an old news update about it, but I can't find the information anywhere. Not on Hans Otten site and not on MSXPro.

Does anyone have the instruction please? Thank you in advance!
