About the DS3800HXPC1D1F
The DS3800HXPC1D1F is a CPU extender board manufactured by General Electric as part of their Mark IV series. The Mark IV (Speedtronic) is a gas and steam turbine control system. It has been designed for all aspects of turbine control, including synchronizing and voltage matching the generator to the system, monitoring auxiliary functions, sequencing the system for startup and cool down, and protecting the system from unsafe operating conditions.
The DS3800HXPC1D1F has 48 integrated circuits. This includes internal timer circuits like Intel's D8254 L4380686. It also has programmable interrupt controllers such as AMD P8259A 8710DP, and octal buffer and line driver PDIPs like Texas Instrument's SN74LS244N. The DS3800HXPC1D1F has 37 jumper switches located across the board. Some of these are multipositional. It also has six resistor networks, which may be placed on the board for data conversion or for voltage division.
The DS3800HXPC1D1F can be connected to other auxiliaries through two male connectors (218A4637-P2) and one female connector (218A4553-1 AMP 533002-1 8706.) It has been factory drilled in all corners, with clips installed in two of these holes.
Markings on the DS3800HXPC1D1F include "6BA04" and "ADS/WMH/EFO" on the lower edge. It is marked A through J on its upper edge. The board has been numbered by tens behind the female connector positioned along its left edge. The DS3800HXPC1D1F uses aluminum electrolytic capacitors and ceramic covered metal film resistors.
