Wayne, there are two clues to what this is for. At the top of the page it
says PIO, and one of the parts in the list is "PC Board, PIO Rev. 2".
I am looking through an IMSAI manual I had handy and the PIO was one of
the boards that I didn't have an assembly section for. However, I have an
original IMSAI catalog, and the PIO board is pictured. I can easily make
out 4 banks of 8 LEDs each (32 LEDs) plus the label on the board: "PIO
Rev-2".
So, we can determine that these are the pieces for an unassembled IMSAI
PIO board (parallel interface).
