it a versatile and powerful tool include the fol- 
loM^ing : 
1. The ability to service multiple users simul- 
taneously, with response times to each 
user commensurate with the complexity of 
the task being performed. 
2. The ability to sample multiple analog 
channels at rates up to 500 samples per 
second with integrity, no matter how 
much foreground or background computa- 
tion is in progress. 
4. 
The ability to store data from multiple ex- 
periments or tests with sufficient descrip- 
tors to uniquely identify all such data. The 
data is transmitted once a day to the Uni- 
vac 1108 FIS system where it is integrated 
into more organized and comprehensive 
files and, thereby, made available for ex- 
tensive statistical and mathematical analy- 
sis. 
The ability to readily accommodate new 
experiments or laboratory tests with mini-
