The useful distinction
Recognize it. Then verify it.
A 34-position, two-row 2.54 mm IDC receptacle is another legacy ribbon form whose physical count should be separated from any assumed floppy or control-bus use. [C243A]
Source-scoped identification facts
Each value retains its exact example, role and measurement axis. Facts from different parts must not be combined into an invented component.

Recorded variant and source limits
- No floppy-drive or other 34-position ribbon signal map is inferred from this connector geometry.
- Ribbon conductor numbering, strain relief and cable orientation remain implementation-specific unless separately documented.

A boundary, not an omission to guess around.
Use the source-backed form or position count only for identification. Resolve ratings, protocol, direction, wiring, cable construction and exact device support from the relevant equipment and component documentation.
Before you connect
What to check
- Identify the exact connector family and variant from the equipment or cable documentation.
- Keep shape, contact count, protocol, electrical rating and device support as separate facts.
- Do not force, rewire or adapt a connector from this recognition record; resolve the remaining requirements first.
What is not established
This field note does not approve a connection, adapter, cable assembly, rewiring scheme or fabricated part. It intentionally omits unsupported pin assignments and mechanical tolerances.
