The Raspberry Pi Pico microcontroller talks to the Intel 80C188 as an I/O device using its PIO - Programmable I/O block.
You will see:
all my fixes I've made to my Slador188 computer's PCB
how the Pico is connected to the address/data bus of the 80188
detailed explanation of how the PIO programme talks to the Intel CPU via the GPIO pins
how to initialise the PIO and use its interrupts to transfer data between the GPIOs and the ARM core
how to handle the interrupts from the PIO in the C code running on the RP2040 ARM core
the tests where we use the Pico as the Intel CPU's I/O peripheral device
