The ultimate function key strip?

Postby crj » Thu Oct 05, 2017 5:58 pm

I can't help thinking that this is perfect for use as a dynamic function key strip. Well, apart from the US$90 price tag, obviously.

A 1024x100 pixel, 10"x1' TFT with 15-bit colour.

One tiny snag is that it requires 200Kbytes of screen memory and it would be a little embarrassing for the function key strip to be higher resolution than the actual display, but it would be hilarious.

And the swapping discs to change the "dynamic" strip :lol:
I know, fonts.

Did the portable Atom with 32x2 (or something like that) LCD character display get fixed?

What's actually needed (beyond a hefty dose of common sense and realism) is some kind of SD card interface that interfaces both to that display and to the BBC Micro. That way you have gigabytes of storage for function key strips and the BBC Micro just has to say "that one, please".

That is so tempting...I must not allow myself to get drunk and accidentally buy one!

I keep thinking I want things like this (USB-driven displays, little TFTs...) for all sorts of projects, and then I realize that I have a perfectly good Kindle Fire tablet that I can write Java apps for if I ever want some kind of console. And that it's spent almost its entire life sitting in a drawer, unused...
