Brand: Pioneer
The Pioneer PD-71 is an IC (integrated circuit) chip that was primarily used in the mid-1970s fordisk drive controllers in personal computers and other data storage devices. This 4-bit smart peripheral (SP) IC offered advanced features like DMA (direct memory access) transfer and support for single- and dual-density formats. The PD-71's functionality helped enable the development of floppy disk drives, revolutionizing the way people stored and accessed data in the early personal computing era.
