Description

From the owner: "I just went through old email; I got my PROM from Cameron Cooper, and Wendell programmed them. I used to have the BW monitor that Steve Jobs modified to have a video input (basically he soldered a couple of wires onto the TV PC board, drilled a hole in the case, and mounted a connector) but that is long gone as well".
Renamed from "Ex Employee 1" to "Elmer Baum 1" (he owned more than one).

History

It was on exhibition at Vintage Computer Festival West 2019 at the Computer History Museum in Mountain View. Achim Baqué verified it and made pictures.Owner is known to Apple-1 Registry curator Achim Baqué.
