Features:
- WDI service identity: Honeywell lists the part as the Winchester Drive Interface I/O circuit board.
- CE build: the -200 version is the CE-compliant WDI board in the WDA-type History Module parts list.
- Assembly boundary: its documented scope is the Winchester Disk Assembly history-module configuration.
The WDI board belongs to the disk-interface portion of a WDA-type History Module rather than the LCN or smart-peripheral-controller board positions.
Honeywell lists a separate -100 WDI board without the CE designation, so the complete -200 number is part of the configuration identity.
A useful service request names the WDA-type History Module, WDI position and exact board suffix together before any storage-interface work begins.
