As we will see, a problem pops up when using the Amiga's analog video. The Diamond Scan manual describes all features and inputs. The scan frequency is automatically selected by internal circuitry; no controls are provided for manual adjustment. The Amiga's oddball DB-23 video connector is a minor problem, but now I knew I had to make a suitable female DB-23-to-male DB-25 video cable. I got out the soldering iron and solder, shielded cable, and various connectors, but soon realized that the Mitsubishi doesn't seem to have a pin for the composite sync signal used by the Amiga monitor. Uh Oh! There arc separate horizontal and vertical sync lines and lots of strange input lines, but none seemed to be for composite sync. I always thought the A-1080 used the Amiga's composite sync, and the separate horizontal and vertical sync lines were left unused. The pinout of the A-1080 cable proved my information to be correct. The A-1080 cable looked like this: The solution is to hook up the separate horizontal sync and vertical sync lines (The Amiga also has those outputs) then hope.
