A Successful Conclusion?
Post-Script: I visited a few thrift/antique stores again this week, and walked away with this Sharp Elsi Mate EL-8131 calculator, for $5. What attracted me to it was the fluorescent display, common to many calculators of the 1970s. It works fine, though my scanner image of it obscures the display, which is reading the first six digits of Pi. And, I passed on 10 typewriters at two thrift stores. Only one or two were of interest, especially a Smith-Corona Super 12 in beige color, whose body resembled a Silent but with wide carriage. The "W" key linkage was broken, else I'd have picked it up. Here's the Sharp calculator:
