It's been a month or so since my last post, but progress has been made. Samples of the replica switches will arrive on Friday. And thanks to Henk of pdp-11.nl, I started in earnest on case design. He let me borrow one of his original bezels/frames - thank you, I'll be careful with it!

It would have been impossible, with hindsight, to exactly replicate the bezel without having the real one at my desk.

I started the CAD work yesterday, and followed the path of least resistance by doing it in Sketchup. Which, maybe, will not be the best idea in the end but I will see. At least I've got all the measurements done for a mostly-finished v0.1 version:

Next version should be good enough to go to a plastics manufacturer for evaluation and testing. Hopefully in the next two weeks, as I visited two of them recently to learn more about the whole process.
