|
Hi
I found PCB with strange chip.
These PCB is described as a CPU board. There are P8228 and P8214 chips on it.
In my opinion chip 57824 is AMD 8080 cpu.
What do you think could it be AMD 8080?? |

As you can see intel chips have two markings
for example P8228 = CG57821
AMD chips have only strange markings
57823 - 2 pcs
57824 |

You can check the pin connection.
For example, if pin 2 is connected to GND, if pin 20 is connected to +5V, if pin 15 and 22 are connected to 8224, etc. |
