I've just got another CX5M, so that makes two now. I mentioned this CX5M before, but there was a 7 month delay in getting this from an eBay seller because there was no power supply, then I left them to look for it, but there was no sign of it. I thought the seller may have gone on holiday or been banned, but nothing like that happened. I have now finally received this CX5M today.
This CX5M comes with the Yamaha FM Music Macro cartridge YRM-104, but there's no manual for it. I have done various searches, but I can't find any manual for it or even a summary of the commands. I think the commands are similar to standard MSX BASIC 1.0, as well as similar to a later music upgrade for any MSX computers, but I don't know at the moment what these commands are. I remember reading a magazine article saying that this language even enables the CX5M to sing, although it can only use sounds found in Japanese.
I hope someone can give me a list of Yamaha FM Music Macro commands, or even tell me where to find the manual.
