1  Using Arduino / Project Guidance / Sinclair ZX Spectrum PS2 Keyboard Buffer on: May 06, 2012, 04:53:07 am
My intention is to use an Arduino Duemilanove (and eventually my own homebrewed clone) to replace the keyboard matrix of a 48k ZX Spectrum using the internal keyboard header in order to utilise a cheap and readily available ps2 keyboard.

The Spectrum keyboard is a 5x8 matrix (40 keys) with more detailed info here

I've seen something like this done with a microcontroller training board that uses a C8051F343 MCu here. My guess (without properly researching it really) is that the ATMega328p doesn't have enough IO lines, I'd just like to stay with an environment that I'm comfortable with.
