Here are two MC6802 microcontroller (AFAIK). I am guessing the date code was 7821 but would ask expert opinion. Thanks!
BTW, this Z80 is a plastic DIP and I date it as 8043, am I right? Thanks again! |

Sorry, just downloaded the pictures to my PC and uploaded to cpu-world forum. The pictures were from arduino.cc
Somebody received some old chips but prefer newer ones for electronics projects. |
