Over in the Yahoo Group for the Cosmac Elf, a few of us have picked up these MSI/88 barcode "terminals" for a couple of bucks surplus. Mine arrived yesterday. They are interesting because they are hand-held 1802 devices with a serial port and either an LED or LCD text display (all of mine are the LED model). I'm trying to assist in the reverse engineering and can *not* find any data on the LED display itself, a MAN2815, nor one of the chips that seems to be driving it, a National DS8867. I have googled for an hour looking for them. No results. Anybody heard of these parts? -ethan
