As home computers rapidly gained in popularity in the early 1980s, third-party peripheral manufacturers also began selling peripherals. For those users wanting to do "serious work", the essential peripherals were floppy drives, modems, and printers. Unlike floppy subsystems, which tended to be machine-specific and 1st-party, the modem and printer markets tended to have major 3rd-party vendors like Epson, Hayes, and U.S. Robotics.

Which computer known for selling to home users was the first to include, as standard equipment, both a modem and printer port (two ports) suitable for 3rd party modems & printers of the time?

NOTE: Ports themselves have to be electrically compatible; requiring no more than a passive cable/adapter and software to use the modem/printer.
