I remember my early SPICE days. In DOS you could write batch files and I had a similar one that sounded off when sims were done. Of course, back in the early 90's one could start a sim, eat dinner, lean back for a nice cup of coffee and cake, chat some more, then "tada" would sound from the office downstairs. Actually the PC speaker wires were connected to an old tube radio so you could hear it upstairs.
Before I had that radio in there I let the batch finish with a few strokes on the Commodore daisy wheel printer. Heavy industrial version, loud. Put a scrap paper in there and then "rat-tat-tat" which you could hear all the way into the backyard.
