Clamps for fixing connectors to the rear of an Apple ][
For use with both the 25-pin and 9-pin front clamps.
Made from .048" galvanized steel.
Magenta lines are for "single-line" laser etching. The semicircular areas at the ends are for cutting or grinding away AFTER the self-clinching nuts have been pressed in.
The round holes are for #4-40 self-clinching nuts (PEM S-440-1ZI) to be inserted after cutting and bending. The vendor I used didn't have tooling that could reach in between the bends to do the insertion, so I pressed them in after delivery using Vise Grips, which turned out fine. It probably wouldn't be that hard to make a custom jig for this.
- Laser cut and bend on the cyan lines, according to the rendering above.
- Separate the two clamps with a saw, and discard the bottom stabilizing strip.
- Press in the self-clinching nuts, they go on the "inside" of the bracket.
- Cut or grind off the extra radius around the nuts.
Made from .036" galvanized steel.
- Laser cut and bend on the cyan lines, according to the rendering above.

The 25-pin version was bundled with the Super Serial Card. See assembly instructions in the Super Serial Card manual.
The 9-pin version was bundled with the Game Port Adapter Kit. I have yet to find those instructions online.
I believe there was also a dual 19-pin version, for use with disk drive adapters, but I haven't modeled that one, or found any good scans or photos.
