   @freemo I remember those days well. My first PC was an IBM clone, 286 a6 MHz, the processor was fast for the time. Not an Intel part, they had moved on to promoting the newer and higher profit 386 gen processors.

   I also bought and installed the math coprocessor for my machine. Needed since I wanted to use AutoCAD, and it required it.

   So I ordered a 287 Intel coprocessor. It was about $300 CAD at the time, early 1991 probably. Would be a lot more today with inflation accounted for, and I was worried of damaging it during installation.

   Turns out it did not work. I don't remember exactly what the symptom was, but not good. I had a $300 part, bought mail order, and might be stuck with it. 😟
