Log Message

Added Fred72's schematics for the Oric MEA8000 speech synthesizer interface, including a bus expansion with slots allowing the connection of the interface at the same time as an Erebus or Microdisc device.
The "Photo" folder also contains a bunch of pictures showing how the interface should look like when fully assembled.
The "Synthor" folder contains some speech software in tap, dsk and hfe format to test the synthesizer.
Included are also a few stl files for building cases for the devices using a 3d printer.
