I thank him so much for sharing this awesome project along with the arduino code. Please check out his 3 part video demostra...
Based on the Arduitape by Duncan Edwards. Download his firmware from http://arduitape.blogspot.com/ and remember to support him and his work.

This is a very basic PCB to put a Raspberry Pi Zero into an old sinclair spectrum 48k case...
Code is by a Mr P J Evans and is called ZX Scanner on Github, I've basically made a PCB of his work and added my own hardware parts!
There's a footprint for an RTC this will use generic Pi RTC code
There's a footprint for an Adafruit I2S amplifier board...i've only put this in for those that want to run...
