#ZX Spectrum+ Keyboard Project
Being a ZX Spectrum fan with a small collection including my original ZX Spectrum 48k from Christmas 1983, I decided to take an empty Spectrum+ case and turn it into a keyboard that could be used with a Rasberry Pi running the Fuse-sdl emulator.
There is some great information on Google about others that have tackled the problem, so having checked out what others have done including a great write up by PJ Evans I borrowed my sons Arduino kit and started experimenting.
This github project is the Arduino code I'm using to drive the keyboard through a Pro Micro and I've also attached a Fritzing diagram of the wiring :O)
Thanks go to all those who have gone before me and shared their information. It made the whole exercise much easier.
#Hardware used
ZX Spectrum+ case. I found a cheap one on eBay that had no mother board, so I didn't need to harm a working Spectrum to make the Spectrum Pi.
ZX Spectrum+ keyboard membrane as the one that came with the case was cracked and brittle.
Micro USB 5 pin female to male left angle extension cable USB 2
Short 12cm USB 2.0A Extension Cable
Super Short Mini Travel Micro USB Data Charge Cable
Short 10cm Flat HDMI extension cable
##Keyboard Electronics
Pro Micro Arduino compatible ATMega32U4
6 x 10k Resisters
ZX Spectrum Keyboard membrane connectors. Got mine from eBay for about £2.50
Piezo sounder. I used one that came with my sons Arduino kit
