Sony PS-X75 Record Player fixed with a Arduino Mega2560
SONY PS-X75 Record Player – 1980’s Blown Sony MB8841-20L microchip fixed with a Arduino Mega2560 Board.
Reverse engineered Sony Chip functionality using the Embrio Software for Arduino:
A long, long time ago in 1980’s Sony produced one of the best automatic record players the Sony PS-X75. The only problem was the main Microprocessor (IC) was prone to breaking.
Our Sony had a broken IC and no one manufactures these anymore and you can’t buy secondhand chips either. We searched the galaxy for a replacement and couldn’t find one.
SO WE reversed engineered the chip using Sony PS-X75 Service Manual and programmed a £30 Arduino Mega board to replace all the functions of the main IC chip.
This video for some could be a bit boring but the heart surgery to replace the main chip with an Arduino board WORKED !! All functions are now FULLY Restored.

Link to all the hard work and software code/configuration using Embrio – You use this pack at your own risk – I do not support or update this code – this is for your own use/research and will require an Embrio Licence to upload to the Arduino Mega Board: Please note I’m using an external light detection Agent/Hardware to ascertain record size – the code would need tweaking / changing to pickup the digital default pins 30 / 31 Sony Light sensor board, but if you have got this far – this shouldn’t be a problem for you 🙂
