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.
Looking for data on the MAN2815 display and Nat'l
Semi DS8867

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?

No response and no data. I'd love to see your Monsanto document.

I have a lot of old semi databooks at work from the 1970s and 1980s. I
don't recall whether I have a Monsanto databook or not, but I'll check on
Monday.

I have a 1986 National Semiconductor interface databook here that contains
a datasheet for the "DS8867 8-Segment Constant Current Driver." Would a
PDF scan of that datasheet be of help?

It's about 44K (only two pages in the datasheet).

Yes! Thanks,
You're welcome.
I couldn't find a Monsanto databook at work, so I can't help with the
MAN2815.
