Last week I found a curious looking board marked MYcom Instruments PLL-DataSender. It has a five position terminal strip on the top edge with some wires dangling from it, a ZIP socket with what looks like an EPROM (it has a lable on it so I can't read the PN), an LCD display and six pushbottons on the bottom edge marked "reset", "mode", "send", "up', "down" and "<cursor>". I can get a display on it and the cursor move things around and pull up four different displays but I can't fingure out what it's supposed to do. Anybody know anything about it? Joe
