I've come across a pile of old TouchSafe II fingerprint scanners.
They're pretty old, and they used a proprietary ISA interface card. I
didn't get any cards with the scanners, so I'm trying to reverse
engineer them far enough to build some sort of adapter.
The devices each consist of a main board, an image sensor + lens on a
subboard, and some finger illumination LEDs on another.
I have had some luck finding the wiring of the LED drivers/voltage
regulators to the (20-pin) connector on the board, but my progress in
the imaging department is blocked by the fact that I can't find a
datasheet for the main imaging chips: a Sharp IR3P66 and a Sharp
LZ95G69. If anyone has a datasheet for these, I'd love a scan.
Of course, if anyone has schematics for either the device or the
interface board, that would be even better
Thanks,
James Laird
