Introduction

PS/2 keyboard to matrix converter for the Aster CT-80 computer raspberry-pi AT49LV001NTFrom the original developer A recently aquired vintage computer came without the keyboard. As this is a simple 8x8 matrix, and the PS 2 keyboard protocol is supported by the Arduino environment, is should be simple to fix. This solution uses a Arduino Nano to interpret the PS 2 keyboard and convert it to an address for the MT8816 Analog Switch Array having a 16x8 matrix. The required matrix is only 8x8, so a smaller array might also work, but the
