As far as this approach is concerned the following comments are 
appropriate. 
1. The inter face was designed as a research tool to overcome 
the limitations of a first generation computer. 
2. While cost considerations for using the large computer did 
not play a role-in the experimental stage it was hoped to 
clarify for which operations a terminal supported dedicated 
computer was suitable. 
3. With the exception of the real time control via the 360 all 
other uses were demonstrated as a research effort. 
4. But it proved soon, that the software effort associated with the link 
was only warranted for routine production which was to be 
automated. 
In the discussion of analytical plotters also those need to be 
considered, which were build for the prupose of automatic image 
correlation : 
1. The AS-11-C and 
2. the AS-11-B1, as well as the latest version, 
3. the AS-ll-BX, 
all produced by Bendix /10/, /11/, <• 
4. also the Bunker-Ramo Unamace /12/ 
» 
5. the Hobrough Gestalt- Plotter ^ 
The requirements for the-operation of automatic image correlation 
devices are so special that they should warrant a more detailed dis 
cussion in a circle of military photogrammetrists, except perhaps to 
say that the flexibility of digital operations has proved extremely 
successful in automatic image correlation.
