FDD reduction / splitter Shugart - 4x IBM:
INTRODUCTION:

3.5 "floppy drives are equipped with a 34-pin connector for connection to a controller that controls the drive and takes care of data transfer between the drive and the processor. There are two main standards for how the signals in this connector are connected - see. the following table. PCs and the vast majority of modern drives use a standard called IBM, older controller(such as Beta Disk for ZX Spectrum) and older drives use a standard called Shugart. The modern IBM standard allows the connection of 1-2 drives, the older Shugart standard handles the connection of 1-4 drives. The situation is further complicated by the fact that modern drives have an internal (internal, hidden) jumper for selecting whether the drive should report as 1 or 2. As a result, if you connect any new drive with a standard 34-pin cable to the controller with the Shugart interface, the drive will report second in order (B :), which is undesirable. This converter is used to convert signals from a controller with Shugart interface (primarily Beta Disk) to signals for drives with a modern IBM bus. The connection to both the controller and the drives is made with simple 34-pin ribbon cables without crossing. In addition, a jumper is located at each of the four outputs for drives A, B, C and D, which can be easily selected whether the drive is internally set to the selection signal DS1 (more common variant) or DS0 (rarer variant).
