I saw a TI Silent 700, one of the portable models.
I've _never_ found
any S-100 or Ohio Scientific at any Hamfest around here.
Frank Mcconnell, bless his heart!, showed up at my door one day many
years ago with a C1P that he picked up at a hamfest up in Gaithersburg.
I can't remember any more what year that was, maybe 1993.
