Since the key mapping appears to be physical, it should be the same on all
laptop/usb keyboards. All the Beeb emulators would be using the same
keycodes.
The image here:
http://wallmobi.net/uploads/pictures/technology/36678-bbc-micro-model-b.jpg
has the '-' and the '=' key being the same key. Just next to the 'zero'.
The mapping from the BeebEm program in userkybd.cpp (full table is at the
bottom) has that -/= key being '1,7', in jsbeeb the notation is the reverse
of that so we're looking for 7,1 in the
https://github.com/mattgodbolt/jsbeeb/blob/master/via.js file:
Line 391: map('\xbd', 7, 1); // '_' / '=' mapped to underscore
so that underscore mapping appears to be wrong? It should be minus and
equals. It's a moot point anyway as it's (apparently) not triggering an
event and inserting a key, nothing happens on screen when you press it!
To debug it you'd need to download the git code and run it on a port per
the instructions. Then do mapping debug prints to show what row/col/assumed
key was pressed. I'm tired and drunk right now so better to CC Matt himself
on this and ask what's happening :) All yours, Matt.
Whilst on the topic, the mapping for the \ and | key is always giving a @,
for unshifted and shifted.

Mark.
