I stumbled on
this recently
If, as is suggested, it's the Ferranti Sirius that Australian ICI Research Labs gave to Monash U, then it's the actual first computer I used - for polymer strain calculations. It was also used for sheep feed supplement simulation - rumen analysis. You could see the mercury delay line memory bits flip.
It was operated/programmed by a team of women, Moira and Janet taught me Autocoder. I'm sure there was a greater proportion of women in computing in the 60's and 70's than there are today - PCs and the Web seemed to be the turning point.
When TPTB turned off the Sirius and told us we had to use the HO IBM 360, the polymer research group (where I worked as a lab technician) decided to use one of these
Programma 101. Shortly after I got a my first job as a programmer - Fortran on a CDC 6400.
