This is a target similar to the HDMI prototype which can read from an original Spectrum keyboard matrix.
It is a work in progress.
It supports the following:
- USB keyboard
- Matrix keyboard (8x8)
- USB joysticks
- HDMI video
- PWM sound (1 pin)
- SPI SD card
I don't know how the original keyboard pins were numbered but mine go from left to right with the keyboard oriented as you would type on it.
