Property:Number of drives per floppy bus
Number of drives that can be attached to each floppy bus. Typically this is only two drives, however some controllers exist where up to four drives can be attached to each bus. In those cases, either a custom Shugart-style cable is used with five connectors on it (one for each drive and one for the controller), or the controller has two connectors on it and standard PC cabling is used to connect two drives to each connector.
Be aware of the difference between a single floppy bus that supports up to four drives, or two floppy buses that support only two drives each. Both options will allow four drives to coexist in a system but work in different ways. Especially if a controller has two floppy drive connectors on it, pay special attention to whether these are attached to the same 4-drive bus, or whether they appear as two separate 2-drive buses.
