How about the 2513 chip made by Signetics and GI? Sometimes called RO3-2513. There are several versions out there depending on what alphabet you get. (You can even get it with Kata Kana).
The newest version uses only one 5 V supply but the older ones used +5,-12, and +12.
Not pin for pin compatible.
