I have a couple of old Heathkit Hero 1 robots. I am willing to part with one, hard to find, SC-01-A chip. It is working well in my robot. The picture is of the actual IC. It will be removed carefully using an anti-static method. I included a short video of this IC talking via the Hero1 hardware. I can demonstrate that the chip is functional via FaceTime call, prior to shipment.

Since this item is static sensitive and I have no guarantee of proper handling once it is removed from my robot, I am selling it as-is. No returns or refunds.
