I ordered 100 pcs of Harris CDP1802ACE from a supplier in China but got "REAL" RCA CDP1802 chips instead. All of them have been tested (by hand on my 1802 CPU Tester.)
These are guaranteed not DOA. They mostly have batch codes in the 400s and most are "RCA X", some are "RCA Z". I am still testing them and will try to identify more information shortly.
