zx81pi

A ZX81 built from a Raspberry Pi, Arduino and a ZX81 keyboard.

The keyboard

This was made using a ZX81 keyboard membrane purchased from RWAP software. The keyboard was stuck to to the outside of a project box and connected to an Arduino Pro Micro. Code has been written derived from code written by and copyright Dave Curran of Tynemouth Software (http://blog.tynemouthsoftware.co.uk/2012/02/arduino-based-zx81-usb-keyboard.html) The keyboard can talk directly to an emulator on a Raspberry Pi, enabling the keyword shortcut system of the ZX81 keyboard to be used.

The Raspberry Pi

The raspberry pi runs the sz81 emulator

http://sz81.sourceforge.net/

Build the emulator (Stock Raspbian)

wget http://sourceforge.net/projects/sz81/files/sz81/2.1.7/sz81-2.1.7-source.tar.gz/download
tar -xvf download

Go to the source directory cd sz81-2.1.7 Edit the makefile, make sure the system wide installation lines are uncommented:

# Comment/uncomment these to choose an installation destination
# System wide installation
PREFIX?=/usr/local
BINDIR?=$(PREFIX)/bin
DOCDIR?=$(PREFIX)/share/doc/$(TARGET)
PACKAGE_DATA_DIR?=$(PREFIX)/share/$(TARGET)

# Local installation within your home folder
#PREFIX?=$(HOME)/Games/$(TARGET)
#BINDIR?=$(PREFIX)
#DOCDIR?=$(PREFIX)/doc
#PACKAGE_DATA_DIR?=$(PREFIX)/data

# Run from current folder i.e. no installation
#PREFIX?=.
#BINDIR?=$(PREFIX)
#DOCDIR?=$(PREFIX)
#PACKAGE_DATA_DIR?=$(PREFIX)/data

May need to install libsdl:

sudo apt-get install libsdl1.2-dev

Run:

make
sudo make install

Test that the emulator runs by typing sz81 at the command prompt
