The Frame Store will store up to 8 fields of video and 8 fields of key. The 
inputs are on aux buses 2A (video) and 2B (key). There are two sets of 
identical video and key outputs, one set goes to the reentry module XX for 
use in the Model 2200 and the other set goes to Serial Output Module 2 for 
external use. The Frame Store Module has all of the circuitry for doing all 
the modifying of the stored video and keys.
