@crowk The nicad battery looks intact, but it’s flat and there’s no cables so I can’t test it. It’s Braille Lite BLT-18:

@crowk I have a Blazie Engineering Braille keyboard that I bought off Trademe for $76 in 2024. I’ve not tested if it works. I bought it for fun, as an interesting keyboard alternative, so I certainly don’t need to keep it. No idea if that’s the sort of thing you’re after?
