Unknown NEC IC's

[Alexis]

Hi,

I've desoldered some IC's off a board from an NEC workstation and there
are two which I can't find any information on. Does anyone know what 
they
are or perhaps have a datasheet?

They are:

D65030C022 (48 pin DIP)
B6103C012 (40 pin DIP)

They could be proprietary custom LSI IC's, I don't know.

Also the CRT controller from the boards is a 64-pin DIP Hitachi HD63484
which will be saved for a neat project. I'm thinking of using a 6809 
with
UniFLEX, or even a 68000 with Minix, and perhaps making some sort of GUI
for it... A long way off but I can dream :)

Thanks,

Alexis.
