Connector & Port Pinout Reference (54 Retro & Bench Ports)
Interactive SVG connector diagrams and 54 dedicated port reference pages covering AV/Video Multi-Out, RGB SCART cable schematics, Power Supplies (PSU DIN & DC barrel polarity), DB9 joysticks/paddles, Commodore IEC serial, cassette/datasette edge connectors, Atari SIO, IEEE-488, 34-pin Shugart/Gotek floppy buses, MIDI, RS-232, USB-C, RJ45, and HDMI.
Click any numbered pin (1–8) on the 262° horseshoe DIN socket to test live pin inspection.
Core Capabilities & Coverage
- Interactive front-view SVG connector stage supporting DIN-5/6/7/8/13, Square DIN-4/5, D-Sub DB9/DB15/DB19/DB23/DB25, SCART-21, Card-Edge, Shugart 34-pin, USB-C, RJ45, and HDMI.
- Pin-by-pin hover/tap inspector displaying Pin Number, Signal Name, Electrical Spec / Voltage Level, and Standard Cable Wire Colour.
- 54 dedicated deep-dive port pages (/pinouts/{slug}) with complete RGB SCART / S-Video cable schematics, required inline resistors (75Ω termination, 1–3V RGB blanking on SCART Pin 16, 300Ω luma/chroma attenuation), and AC coupling capacitors.
- Prominent Polarity & Voltage Trap warnings preventing catastrophic cross-plugging of physically identical DIN and barrel power supplies.
Step-by-Step Workbench Workflow
-
1
Select Connector Category or Target Machine
Choose a port from the Interactive Connector Diagram dropdown or filter the 54-port directory below by category (A/V & Video, Power Supplies, Joysticks & Input, Disk & Serial Buses, Modern Bench) or Machine Hub.
-
2
Hover or Tap Pins on the SVG Connector Stage
Hover or tap any numbered pin on the interactive SVG diagram—or click its corresponding row in the pinout table—to highlight the pin position, signal direction, expected voltage, and wire color.
-
3
Verify Mating Orientation (Solder Side vs. Socket Front)
Before soldering a custom DIN or D-Sub plug, confirm whether you are viewing the chassis female socket (front view) or the cable male plug solder buckets (mirror image) using the orientation notes on each dedicated /pinouts/ page.

Open the Full Port Page for SCART Schematics & Resistor Values
Click "Open Full Pinout & SCART Wiring Guide" to view complete cable wiring tables, sync attenuation resistors, audio summing networks, and continuity test checklists.
When building an RGB SCART cable for an Amiga, Atari ST, BBC Micro, or Sega Genesis, always check whether the console outputs TTL-level CSYNC (5V p-p) or 75Ω video-level sync—TTL CSYNC requires a 330Ω–470Ω series resistor to avoid rolling or damaging the display's sync separator.
Identical Plug, Lethal Pinout Traps: Never plug a C128 5-pin Square DIN PSU (9V AC on Pins 4/5) into an Amiga 500/600/1200 (+12V/-12V DC), or a C64 7-pin DIN PSU (9V AC on Pins 6/7) into an Atari 800XL! Likewise, ZX Spectrum 48K and C16 use 9V DC Centre-Negative barrel jacks, whereas Amstrad CPC uses +5V DC Centre-Positive.
