More Info (was Re: HP 2100S microcode blanks?)

[Jay West]

I did find some chips on a microcode board that tell me what chips they are.

However, I can't find any source for those chips, and I can't find any list 
of substitutions!!

The part is Harris M1-7611-5    8211

I'm assuming 8211 is the date code. This chip isn't in the databooks I have. 
Anyone have a clue as to a substitution part? A datasheet on the original 
part would be a help too.

THANKS!
