Does anyone in AppleFritter land have any info, schematic, photos, etc. of the old Apple Graphics Tablet Interface Card STYLUS?
I'm looking specifically for information pertaining to the Stylus itself. I have the Tablet and interface card but am missing the Stylus for it.
I know it has a coil (inside the pen) and possible other circuitry, but I don't have any details for it.
I want to make up a pen that will work with the tablet. Found a good readable schematic of the Tablet's interface board here: Apple ][ Graphic Tablet Schematic
Based on the circuitry, there's an input to an Op-Amp that appears to be from a coil type arrangement, but there is also a transistor acting like some form of gated switch that is also triggered by something from within the Pen.
Does anyone have photos of the pen's internals they can share, possible a schematic, and (potentially) obtain an ohm reading of the internal coil?
If I can get this information, I think I can succesfully make a stylus. Thank you all in advance.
