Eric,
forwarded to the folks at Johns Hopkins with the need, thank you very
much!
They designed the board so they are likely to know what the part needs
to do, and you are correct it’s for ground support, so presumably they will be
able to design a replacement if necessary. They may also have the datasheet.
I Got two other responses as well, one with a part number listing (with
52,000 parts available, which is pretty suspicious) and one offering to design
a module as you suggest, and forwarded those as well.
Very much obliged!
