I was working for a financial software house called ACT Financial systems. Their main product, Quasar was an investment management system written in Mumps. It ran on Digital VMS and Sequent (Unix) systems.
This was typical of the projects I was involved in at ACT. I was in a small team of 3 people which took the project through the full life-cycle. We designed the screens, coded the module, did unit and integration testing and wrote user manuals.
I was later providing support to this module, and many others I worked on at ACT.
