I found a file on my server that's labeled R100 EEPROMS that have a tx.bin and rx.bin file in it. I'm guessing it might be blank codeplugs for making eeproms? I don't know if anyone is interested in it. I've got 1 known working R100 and 3 parts units with various pieces missing that I've been needing to work on. I built the programming cable which was easy enough and have it running on my 486 machine quite well. Never can get the motivation to finish them.
