The U808D is an Intel 8008 clone made in former German Democratic Republic by VEB Funkwerk Erfurt (FWE). It was used in one of GDR's first computers, a Robotron K 1510 from 1977 (German technical documentation here).
My U808D came in its original box, which is pretty much like a matchbox with metal coated paper inlay. Here's a picture of it.
