23 PIN D-SUB FEMALE to the Amiga
6 PIN DIN MALE at the Monitor
This cable connects the Commodore Amiga’s proprietary 23-pin DB23 video output port to the Commodore 1084 colour monitor, introduced in 1987. The Amiga DB23 carries analog RGB signals (Red, Green, Blue on pins 3–5), composite sync (CSYNC* on pin 10), and ground returns, enabling a direct analog RGB connection. The 1084 monitor accepts analog RGB via its 9-pin D-sub input, providing a sharp, flicker-free picture compared to composite video on compatible Amiga models including the A500, A2000, and A3000.
| Amiga | C1084 |
|---|---|
| R | 3 |
| G | 4 |
| B | 5 |
| SYNC | 10 |
| GND | 16 |
Signals
- R — Red analog video, 0.7 Vpp into 75 Ω
- G — Green analog video, 0.7 Vpp into 75 Ω
- B — Blue analog video, 0.7 Vpp into 75 Ω
- SYNC — Composite sync (CSYNC*), unbuffered TTL-level output from the Amiga DB23
- GND — Signal ground
Notes
The Amiga side uses the 23-pin male DB23 video connector; the monitor side uses a 6-pin DIN male plug. The Amiga’s analog RGB outputs on DB23 pins 3, 4, and 5 are unbuffered. The 1084 monitor also offers an 8-pin DIN input for TTL-level digital RGBI from Commodore 8-bit computers, which uses different signal levels and is not compatible with this cable.
