Apple II+ - Super Serial Card II - DB25 Cable Clamp

Apple II+ - Super Serial Card II - DB25 Cable Clamp

Description

When I bought a Super Serial Card II for my (Unitron clone of a) Apple ][+, I realized that it only came with the //e backplate for securing the DB-25 cable to the back of the computer. Of course, I decided to try to build one myself, based on some reference images I found on eBay listings and from the Super Serial Card's manual itself. Overall, I think it's a pretty decent reconstruction, though there are a few things I wouldn't mind changing. That's why it's still a WIP; I'll probably do an update to it someday. The screw holes are for example too big in diameter, so the screws don't fit too well, especially in the back panel (and if you're screwing any cables onto the DB-25 port, they'll probably try to bring the port with them when you take them off). Also, there's still quite a bit of movement in the clamp itself, especially when the lid isn't on. Not bad for a few hours and ten or so test prints, though, so I'll probably be able to fix those things if I revisit it sometime. Anyhow, I figured I'd share this, as I couldn't find a model anywhere else online (if I did, I don' t think I would've tried to make my own, but it was a good experience nonetheless :] If you have any questions, comments, or other ideas about this thing, feel free to let me know. - Matthew Piercey (@MTPiercey on most things) CAVEATS: It's designed for my Unitron clone - on an actual Apple computer the cutouts in the case I believe are lower or bigger, whereas with mine the case lid would not have been able to close if I hadn't cut the big notch from the top. Also, I made it in FreeCAD, but I'm still getting used to it, so my source file doesn't make much sense at all. You're honestly better off with the STL mesh if you want to print one of these things yourself, even if you want to customize it (I've tested importing them to SketchUp and it works pretty well).
