It would own if someone could make a set of red-orange function keys, preferably labelled ƒØ through ƒ11 instead of F1 to F12. I don't know that I've seen any Cherry caps in that perfect shade of red-orange, but I have seen group buys with double-shot olive drab keys (like the arrows and copy). It would work best with a FILCO MX black keyboard – not only are they linear, but they have the red LEDs. (Never used MX black – the Beeb is the only linear keyboard I'm familiar with, and linear isn't really my thing; the tactile bump in MX browns is definitely subtle at speed, but it feels good.)
Never realised that the rest of the keys were dark brown, though – always looked black to me. Under intense torch light, though, they're clearly brown. However, you can't get the BBC look with dye, since they were, after all, double shots. You're better off going with black group buy double shots as that would give you the same rounded kiddy font.
What I do want is Archimedes A3010 blue-green function keys – need to be ALPS, so that I could use them on my Acer (ALPS-a-like), Tulip, or, more likely, my Tactile Pro 3 – all ALPS interface. There's on way in hell I'd ever get them in ALPS :°( ALPS just gets no love any more.
