Following on from the ZX81 USB keyboards I've been building, next comes the Spectrum. The Spectrum has a lot in common with it's predecessor, but there are a few differences to the keyboard. The main difference from a software point of view is that there are now two shift keys. What was the ZX81's shift key is now caps shift, and what was the . / , key is now symbol shift, and there are various symbols dotted around the keyboard in red.
Tynemouth Software Etsy store, look out for more of these coming soon.
Note: I have stopped using Leonardo based boards and moved onto my own custom PCBs and firmware for ZX81, ZX Spectrum and Commodore computers. There seem to be some issues using the Leonardo keyboard library with things like the Fuse emulator. If you plan to use an emulator, either see my Etsy store, or try the older V-USB based design.
