  - This is a 24 bit computer made of RTL logic with channel I/O. 
 
- This machine was made for NASA to compute the vibration analysis on the Saturn V
moon rocket. It is credited with removing several flaws in the design
that would have meant a total disaster had it tried to launch. One of these was a fuel line that in
resonation, flexed 6 feet and ruptured. 
 
 
- Only two of these machines
were made. 
 
 
- Cycle time was 1.5 microseconds
