A week or so ago, there was an article on the tech blog site us vs th3m about my vintage computers as USB keyboards with links to my Etsy Store, and that seems to have generated quite a bit of interest. So I've been quite busy this week building various USB keyboards.
ZX81's and Commodore 64 Raspberry Pi casemods in the past, but I hadn't done a Spectrum+, and it seems to fit quite well.
Raspberry pi chameleon, a nicely packaged distribution of emulators, of course the Spectrum would be the first choice.
