I am working on an accessory for the ZX81 to give it VGA, Sound, and Wii Classic Controller features using a Propeller.
I plan to release everything so others can make one if they want to. Well, not quite "everything". I don't really want to release the source code (PropBASIC), but I will provide the binary to program the Propeller.
Could I still call it "Open source" ? I mean I will release the gerbers, parts list, assembly instructions, Propeller binary, etc.
I don't want to call it "Open source" if it doesn't really meet the definition.
