Information on National Semiconductor 2900 family needed

[bruce]

I'm looking for information on a National Semiconductor 29XX family chip. It is a 4bit ALU slice. The number on the part I have is SD42151(possible "house" number). It is a 40 pin plastic DIP and is used with an AMD 2910 controller and a TI SM48032 Carry generator. The only ID I can find on the chip is "8 Function ALU - 2 Port."

ANY information on this chip would be appreciated and if anyone knows of an equivalent AM 29XX series chip I would be QUITE appreciative.

Cheers.

I can't find any info on SD42151 part number, I think it's AMD 2901. AMD 2901 is an 8-function ALU, and it's often used with AMD 2910 microprogram controller and AMD 2902 carry generator (probably the same as TI SM48032) as a core of MPU.
