Anyone have any info on the NEC D2167D-2?

Hi, all,

I'm going through a box of random ICs and one particular item is not
showing up on my searches outside of a couple eBay auctions for chip

The IC is a 20-pin ceramic body with side brazed legs, gold pins, chromed
lid, with NEC D2168D on it with "-2" painted on the ceramic and date codes
from 1984.  It's almost certainly a RAM chip of some kind, but I'm not
finding any pinouts or data sheets.

Anyone recognize this?  Anyone know a system that uses them?  I have more
than 10, and since I haven't run across them before, I probably don't have
a machine that needs them.

Thanks for any tips.
