Ok, I thought this was going to be easy. I thought that with the right cable, I could connect my B128-80 to a Magnavox 1084 or another Magnavox 80 monitor I have available. The composite output on the B128 is terrible, so I wanted to use the RGBI connector. I sacrificed an old 128 80-column cable so I could put a 5-pin DIN on one end for the B128. I immediately realized this was not quite as easy as I thought. The monitor expects separate Red, Green, Blue, and Intensity (I know, hence the abbreviation RGBI) plus HSYNC and VSYNC, but the B128 only outputs Video, HSYNC, and VSYNC. I tried using just one of the colors to see what would happen. On the Magnavox 80, I got an image that rolls, but nothing at all on the 1084. So I tied the colors all together, same thing. I had no idea what to do with the Intensity line.
Is there a way to connect the B128 to this type of monitor without using the composite input? If not, do I need a true monochrome monitor for this computer? Steve Gray, what are you using with your B-Series?
