I recently picked up this Apple IIc and discovered it had a fingerprint board inside which is tapping directly into the CPU.
The IIc runs fine with it plugged in. However, it doesn't do anything when I press the button. I can't find the manual for this card anywhere. I have found the manual for the version that goes in the Apple II/II+/IIe. I also tried running the VDAP program that goes with the regular Apple II card, but that said it wasn't installed. Does anyone have the manual or a version of VDAP that would support this card??
You can see a bit more detail in the video I did about this IIc at 16:47 https://youtu.be/XVxfU1y2GnM
Any help or suggestions are appreciated!
