Hello, I just completed one of the projects I've been working on for my calculator Web page and thought it would be of interest to some of you. I've published a directory of desktop calculators that were manufactured from 1964 through approximately 1975. There are nearly a thousand machines listed in the directory. Included in the directory is information such as manufacturer, model, display type, # of memories, and decimal setting. There is also a "notes" column where I list if a machine has other capabilities such as programmability or scientific functions. There were quite a few high-end programmable calculators made during this time, many of which were advertised as being more cost-effective than mini-computers of the timeframe. Examples would be the HPs, the Olivetti Programma series, Compucorp machines (also marketed by Monroe and Dietzgen), some Sharp machines, and a few others. The directory is linked from the "desktop calculators" section of my Web site. It was quite a lot of work to pull all this together, I hope some of you find it useful and enjoyable.
