A DIP 5719 Gary
A PLCC 4393 Fat Gary

The Gary chip provides bus traffic control signals for the A500/A600/A2000 address and data bus.  It was a consolidation of a large amount of descrete 74-series components and PALs on the A1000.  The original GARY chip in the earlier Rev 4.x series shipment of the A2000 may have been the initially outsoured component from Toshiba.  C= Field Service Bulletins suggest replacing it with the now-common MOS-made version.

The Fat Gary in the A3000D/T & A4000D/T is a PLCC chip, and does similar duties in those machines.
