GandALF Drive Logic Array Substitute: (replaces 325572-01 for the 1541) is a replacement module for the MOS 325572-01 custom IC installed in all VIC-1541 and 1541 disk drives that use the mid sized boards (1540050, 250442 and 250446).

The Gate and Array Logic for Floppy is about the only component on the electronics board of the standard 1541 and the later VIC-1541 for which there is no current version or cross reference on modern components list.

Using technology similar to what's used on PLAnkton, Eslapion (Francois Leveille) , e5frog (Fredric Blaholtz) and electrical engineer (Sylvain Brisebois) were able to create a fully functional and perfectly compatible module to replace this IC which is specific to the 1541 series of floppy disk drives and only ever made by MOS or the Commodore Semiconductor Group.

Abilities in electronics, and soldering skills may be required if you have no socket or its damaged before installing this item..
