I got one also, and the LED displays are interesting. Did you ever get a
response to your inquiry last year? I found this old Monsanto document that
doesn't give much info and would appreciate if you had anything else.

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?
