I think I have a couple of old SAD1024 MOS shift registers from when I
was collecting deeply discounted items from the local Radio Shack
"Manager's Table" as a kid.
I had thought one day to make the audio echo/delay circuit I think I
saw in an old Forrest Mims circuit book, but a solid-state acoustic
delay line emulator sounds like a much cooler place to put them.
