Possivelmente. Mas não sem algum esforço.
Veja a discussão neste thread de teclado mecânico aqui como bem como esta discussão neste fórum do Arduino aqui .
Basicamente, cria-se um adaptador que converteria a saída do conector DIN de 5 pinos no Amiga. teclado aa conector USB moderno.
Esta página descreve o uso do Cypress EZ-USB (AN2131) com Firmware específico do teclado Amiga (EzHID Amiga Keyboard Firmware) para converter a entrada. Mas, conforme descrito em este thread de teclado mecânico :
That is a protocol converter-firmware for the AN2131 serial-to-USB
chip, used as an adapter for an external A2000/A3000 keyboard. A
compiled file is available in the archive that you can download from
EzHID's web page. The problems seem to be getting hold of a device
with that chip and programming it ... Not exactly a ready-made
solution.
E este tópico neste fórum do Arduino explica como converter um Arduino Leonardo em um Amiga 500 / Interface de teclado 1000/2000:
this turns your Arduino Leonardo into an AMIGA 500/1000/2000 Keyboard
Interface which means that you can use your Amiga Keyboard as an HID
Keyboard on your PC/Mac/PS3/Raspberry Pi or whatever. (like keyrah)
All you need is the Amiga Keyboard and the Arduino without any shield
or additional hardware. It does not work with Amiga 600/1200 Keyboards
since they have no serial interface. It's also possible to hook up 2
digital joysticks (e.g. competition pro) with db9 connector.
Dito isso, parece que, com base na discussão sobre esse teclado mecânico fórum —uma placa de desenvolvimento Teensy USB pode ser uma opção mais suportada para o desenvolvimento geral de tradução de entrada de teclado:
The Teensy USB Development Board by PJRC is a line of small
inexpensive circuit boards with a microcontroller that offers a
plethora of I/O pins and a USB interface.
The Teensy version 2.0 has become popular for many enthusiast keyboard
projects, either as a keyboard controller or a protocol converter. It
sports a AVR ATMEGA32U4 8-bit microcontroller ("µC"), 16 MHz clock (16
MIPS), 25 I/O lines and a USB client port. There is also a larger
variant: the Teensy++ 2.0 with a AT90USB1286 chip that has more I/O
lines.
The Teensy 3.0, Teensy 3.1 and Teensy LC have microcontrollers based
on ARM Cortex M-series. These have so far not reached much popularity
because of lack of available firmware. The LC model is a "low cost"
variant that is (mostly) pin-compatible with the Teensy 3.1.
