TRS-80 Models 1, 2, 3, 4, 12, 16, 6000 could all use up to four floppy drives.  The 4p was limited to its two internal floppies and a 12 or 6000 with a built-in hard drive was limited to one internal and two external floppies using Tandy hardware, but third parties (specifically Bob Snapp) expanded on that.
