This project is an PS/2 keyboard controller for the ZX Spectrum. It makes it possible to connect and use an external PS/2 keyboard with the spectrum. It's based on the a500kbd code: https://github.com/jtsiomb/a500kbd

The PS/2 keyboard controller is built around an AVR atmega168 microcontroller. The firmware reads PS/2 keyboard scancodes, maintains a virtual spectrum keyboard state, and monitors the address bus to keep the data lines going into the ULA continuously up to date with the selected key row state.

NOTE: not done. check back soon.
