Universal Equipment Modtiles
This document has been updated to include new naming conventions.
Acronyms and abbreviations for the new names are identified in the text
using parentheses.
Each configuration of the SL-1 consists of a
nuniir
of
Univ&sal
Equipment Modules (UEMs). Each module can be identified by its
function. There are nine different types of UEMS:
