An Arduino interface for 8088 CPUs

An Arduino interface for 8088 CPUs. Contribute to dbalsom/arduino_8088 development by creating an account on GitHub.

Where it differs from Raspberry Pi based projects is that it uses an Arduino DUE to supply enough GPIO pins to operate the 8088 in Maximum mode without requiring any shifters. We can also enable inputs such as READY, NMI, INTR, and TEST, so we can in theory execute interrupts, emulate wait states, and perhaps simulate FPU and DMA operations. This is useful for investigating the timing and operation of certain instructions without needing any external software integrations, however it is restricted in the number of memory reads or writes it can support, due to the limited RAM on the Arduino MEGA (8k!)
