I had to make an application for a brokerage with a S/3
model 6 which would stand at a fair. The program was for calculation of the monthly
installments of a mortgage
(Entries mortgage amount, term and interest rate, and
then program would calculate the monthly payments).
Obviously the program was in RPG. The
program did not fit in the memory size of the computer of only 8 kb(!).
have spend days and nights sitting tinkering to get it within the memory boundaries.
Upgrading the memory
was not an option, or too expensive, I worked then for a software house, and
apparently the cost of my hours were less than the memory expansion.
According to me the S/3 discs were 1.25 MB (100 tracks), but they
could be made 2.5 MB (200 tracks) if something (a jumper) was changed in the read-write unit of the
But that would meant a substantial increase in computer rental / lease. So
you cut back on data storage. Here started the millennium bug/problem.
