Back in this time, early to mid 1980's, I did some work in a programming language called Savvy. It was some kind of tool to build expert systems based on data. Google doesn't seem to know about it. It was very obscure but my father and I built a tool for the Institute of Metals and Material Australia for assisting engineers/metallurgists pick the right kinds of metal alloy for a specific job. It's the first ever useful software I wrote but I can't find a record of it anywhere. Time has erased it.
We had used a primitive rolling hand scanner to scan in huge tables of metal alloy data along with recommended usages. My father wrote the query engine using Savvy and I wrote the text based windowing UI.
Would be neat if someone could turn up some record of it somewhere. My father has been retired since ever and has no records of the system either.
