this is great Jim, below is pix of my 20+ slide rules that I rediscovered hiding in my shed that I had all but forgotten about. In the background is the culprit that started their demise, a Friden 130 calculator. The 130 was the first solid state desk top calculator that was released in mid 1960's and takes pride of place in my electronic calculator collection. It used discrete components and an acoustic delay line for the memory plus a CRT for the display, amazing for its time.
