The use of second generation computers made several 
simplifications possible. 
1. Due to core memory it was now not necessary to time 
optimize the program 
2. This facilitated the use of floating point 
routines, if time was not of extreme importance. 
3. Assemblers which were easier to compose for core 
computers were available for more efficient 
assembler programming . 
4. New fast access storage devices such as the 
magnetic disk could easily be added relieving the 
problem of limited memory, working with overlays . 
be) Another approach 
was of course to overcome the limitations of the 
existing computer 
by building an interface to a large third generation computer. 
This was carried out for the AP/C installation at the University 
of New Brunswick from 1968 to 1970. 
This version 2 of the AP/C was equipped with a Bendix 
AP/C computer and with additional controls to the zoom 
optic for rotation and magnification. 
The advatages of k third generation computer, such as the 
IBM 360/50 wer* obvious: 
They consisted in 
1. floating point hardware 
2. higher speed 
3. larger storage 
4. the large possibility of fast storage and I/O devices
