Hi, I'm new with this stuff and I'd like to build a simple system based on an 80C390 CPU. Since I haven't understood how to connect external peripherals to the address and data bus, can someone help me and send me the scheme of a basic input (8 switches) and a basic output (8 leds) peripherals connected to the micro and mapped in one of the 2 4megs banks?

And another thing: it's best to map the peripherals in the ram accessed with CE0-3 or in the other block, accessed with PCE0-3?

Bye and thanks!
