This recently taken in CX5M is in amazing condition, and complete with box, manuals, cables and PSU. I have tried it with the keyboard into an old CRT and it works perfectly. The flickering on the screen in the video is just due to the camera not matching the monitor. Please don't hesitate to contact me, if you have any questions. Here's a short description of this rare, early 80's computer from Yamaha...
