Here we go: http://www.cx5m.net/ (dunno why it is not opening, but you can find it on wayback machine, and I must have it ripped somewhere) is THE site about the CX5M. You have the pinout of the video cable on the manual, which is here: http://download.yamaha.com/api/asset/file/?language=hu&site=hu.yamaha.c… It is easier to buy a disk controller, these can be easily found in Brazil. I can assist you in getting one. There are also SCSI and IDE controllers. Drive can be used anything from 180 to 720K. It is usual to have 360 and 720k disks. Anything pc-compatible in the 360 and 720K realm can be used, just don't forget to change DS1 to DS0 on the drive. Schematic can be found on the service manual, let me see here... ftp.funet.fi/pub/msx/docs/service_manuals/yamahacx5musm.pdf ftp.funet.fi/pub/msx/docs/service_manuals/yamahacx5msm.pdf And of course, the CX-5M FAQ http://home.online.no/~eiriklie/CX5MFAQ.html May I be of more help? :o)
