C64 Serial Port finished!

Well done!. One comment, I would seriously recomend putting some kind of strain-relief on the wires at the edge connector. What I normally do is screw a couple of tapped spacers to the connector feed, then screw a bit of small angle brass (L cross section) to the other side of those, and then fit cable clips to that as appropriate. Otherwise you will go mad continually resoldering thr wires. Don't ask how I found that out :-) My first guess was some kind of tape cartidge box (the translucent plastic and the way it opens gave it away). I see others have correctly said it was a TK50-like box. Well, I viewed the pictures in an local internet cafe, and the box looks rectuangular (as opposed to square). Either something is distorting the picture (does it look square to anyone else?) or you've hit the well known perspective problem that affects everyone who takes close-ups without a technical camera. -tony
