Back in the long ago time, DEC created one of the first rule-based expert systems. The system was used by their sales folks when filling orders for PDP and VAX machines to ensure that the requested configuration included all the components, cables, software, etc. required. The expert system was called R1.

25% in Maths, 25% in English, 25% in Art, and 25% in Music. That's 100% - so what's the problem?

In my student days, in the very early 1980s, I was chatting with an architect about computers. She told that their office had just bought one. If you are old enough to remember computers in 1981-82: We made 'graphics' on the line printer from '|' and '-' characters and pixels from white (space) to black (a lot of characters printed on top of each other). Not quite the quality you would like to present in a prospect presented by a large architecture office. So I asked how they used the PC. They had a floppy disk with the Norwegian Building Standard (or whatever it is called in English - a set of construction requirements that every contractor must adhere to) in a database format, and a second floppy with the dBase executable. Before they made a bid, they had this dBase application go trough it, checking it against the Building Standard to see if the bid included the cost of every single little piece required by the Standard; invariably, they were reminded of things like door stoppers and cabinet door handles that they had overlooked when making the cost calculations for their bid. In the first bid processed by this software, they were reminded of so many such small cost elements that they increased their bid by more than the cost of the computer and all its software - yet, they won the bid. So the PC paid for itself in full through its first job! I asked the architect what size hard disk they had. No, they had no hard disk. It was a twin floppy system. The specific bid information was stored on the floppy with the dBase software. But ... I said, if you run it on floppies, then you can start the program before you go to lunch, and it might possibly have completed when you come back! The architect gave me a look as if I was from a different planet. Earlier, they did this kind of checks by hand. For a small bid, it might take a man week, for a large project maybe a man month, maybe more. Now it is done automatically in an hour or two, with no manual effort required at all!

I did some programming on MicroVax. Pretty cool machine at the time. Amazing OS.

You had a very good path. Similar to my experience. Not building standards, but deeds, titles and plots for real estate. The simplest system was a data entry machine that wrote to floppy and then to tape. It was portable. I took it to a number of small rural title companies where they entered the data. I later collected the data, transferred it to paper for the title company to use for title searches. back in mid 70's, early 80. It was made by NCR if memory serves.

I also had access to a VAX cluster. One could run a program that could be spread across the cluster (network) with the right system calls. Been so long ago, I can't recall the details, but I was fresh out of computer science grad school so the exposure to such a system was quite exciting. Used VMS version of Fortran.

There was an alternative - the Calcomp plotter. You wrote commands to move a pen around with the tip either up or down and could draw whatever complexity of graphics you needed. In my case, when I did my M.Sc. in 1971 I was developing a continuous simulation hydrologic model that could calculate flows at a point on a river over a long period of time using various meteorological data. It had a version which produced hourly flow estimates. With maybe 20 years of data, the hourly output was a lot of numbers. To illustrate the results for my thesis, I plotted a graph of the observed flows and the simulated flows on the Calcomp plotter. The x-axis was about 8 foot long. The first time it ran, the plotter operators turned it off as they thought I'd programmed an infinite loop and was going to ruin an entire roll of their very expensive plotter paper!

Sure, you had pen plotters, for line drawing. They were nice for engineering drawings, but certainly could not replace an architect's pen drawing of the park around the new house, with kids playing on the grass, people strolling around, trees and flowers, drawn in perspective, filled in with watercolor. Pen plotters were not suited for drawing surfaces as such - they could draw the borderlines of the surface, but not the surface itself, the way and architect could fill in with watercolor or shading with his pen. Any "natural" object would look very un-natural if you attempted to draw them on a pen plotter. More expensive pen plotters could handle pens of different colors at the same time (with the cheaper single-pen plotters you could of course draw all the red lines first, then replace the pen to draw all the blue lines, and so on, but that was very cumbersome), but limited to clear, saturated colors, no continuous tones. You can't do dithering with a pen potter! The cornerstone factory of my home town made internationally recognized flatbed plotters of huge sizes - they had a drawing area of up to a few square meters. After creating the engineering drawing, you could replace the plotter with a steel cutter, cutting according to the same plot lines the plates that were to be welded together to a ship hull. (They also had the computer controlling the automatic welding machine.) In those days, it wasn't called 'robotics', but 'numeric control' (NC) tools. I believe that they developed the plotters and steel cutters during the 1960s; their golden age was in the 1970s. That equipment was most certainly not priced for the hobbyist market :-)
