Does anybody know what this chip might be? Of course I suspect it's an ALU, but google comes up empty ..
DEC 19-23095-03 / ALU03
812B
D/C 8633
72-pin PGA (2 rows) |

Hey, you're supposed to know without those figures, John 
But since you're asking:
bottom left
812A
8421-50 (or B421-50)
bottom right
SCOT
8633
(I presume that's Scotland and D/C) |

cool will do some digging but guessing TI gate array, for some VAX type processor (like the VAX750 gate arrays used to implement the ALU etc)
