What you did Macus is actually fairly common. This is easily done by buying a docking station. Most docking stations allows you to hook up a monitor, mouse, keyboard, printer (old printer cable style), Ethernet, and usually gives you additional usb ports. You usually can charge the laptop batter(ies) from the docking station.
Docking stations have been around almost as long as laptops.
Glad to see you are able to use that laptop. I hate seeing laptops go to waste.
