UM8329BT Description
The UM8329/B is an MOS integrated circuit designed to plement either the 179X or 8272A (765A) type of floppy disk controller chip. It incorporates a digital data separator, write prepensation logic, and a head-load timer in one O.3-inch wide 20-pin package. A single pin will / configure the chip to work with either the 179X or 8272A type of controller.
