Description:

General

The ACC 83000 chip set is designed for system designers to build 100% compatible IBM PS/2 Model 30 systems. The ACC 83000 contains two VLSI chips.

The ACC 3100 provides system control signals, and the ACC 3000 is the I/O controller. The ACC 83000 supports a local CPU bus, a system memory bus, and compatible Model 30 buses. The system clock generates 24, 8 and 1.84 MHz clock timing. Up to eight I/O channel interrupts with sharing capability are available with variable wait states.

• 100% IBM PS/2 Model 30 system support gate array pin to pin compatible
