Thanks for this nice overview. I'm watching this because I have to change the battery and the screen on mine. I also wanna change the floppy for something else

I wonder if those other two solder pads by the PLG socket + cable, can have sockets installed and then maybe flash the firmware EPROM chip with the MU128 BIOS? Might not work but interesting thought to have a cheap upgrade.
Nice to see the internals, to try decipher what makes this odd unit tick. Especially since there is no service manual readily available online. Thanks!
Anyone explain how cards work ? I'm looking for a solution to have 8-16 digital channels of instrumentation from a sound module (r-bus/Roland) to a YAMAHA-Digital mixingdesk. ....Thanks...
i really wanna know, what's disk format of dps12, i used the bluescsi, it works, but i cant read the image in the computer, so i must burn a cd then used the official tool (called what, i forget, but i know how to found it in google) to get the wav files, but i dont have a scsi cd burner, so i need to read the image file on the computer...please tell me...
I still have the Yahama MD4 I bought in the 90s. The unit still plays discs, but it won't eject the discs. I doubt anyone around here works on anything like this, so I may have to try my hand at electrical repair.

Será que consigo arrumar o meu...pois ontem descarregamos o arquivos sys ex .. e voltou a tela igual ao seu ..mas meus teclados não respondem .. 😢😢😢😢😢 será que poder todo o conjunto de membranas que não dão contato e as borrachas ??
I have a Roland U-220, it's still usable even today. But unfortunately the value down button on it doesn't work. Replacing the switches looks straight forward, I might considering it in the future or possibly getting another fully working U-220 and keep the other U-220 as a spare.
try to disassemble and wash the button panel thoroughly with only water by gently pressing them. then let it dry well. then try it. 90 percent of the time it works!
