The main CPU is an AM9080, a 8080 clone (1820-2006).

Initial startup

After cleaning the machine started but with an error message:

U32 was a socketed chip with the HP number 1818-0348 which should be an AM9102DPC, a 1024x1 bit static RAM. Swapping the chip on other places where it is used follows the chip around so it is the chip..
