Description
The GE DS3800HUMB1B1B is a Universal Memory Board associated with the Mark IV Speedtronic turbine control system. The board contains multiple erasable programmable read-only memory (EPROM) devices, 30 jumpers, one reset toggle switch, and one red LED indicator. Its modular connector and retention levers support installation within the intended hardware assembly.
Functional Role and Board Layout
The DS3800HUMB1B1B is identified as a Group 1, normal-assembly board within the Mark IV series. Its memory-related hardware is based on multiple EPROM devices, while the onboard jumpers provide configurable hardware links. The available documentation does not specify the individual jumper assignments or the memory capacity of the installed devices.
The board has a modular connector at one end and retention levers at the other. One reset toggle switch and one red LED are also present. The LED's exact diagnostic meaning and the reset switch's effect on the host system are not established by the supplied information.
