Needed one of these for my MCS-4/40 set

This is the Keyboard/Display Interface chip for the MCS-4.

Hm missed this one.

Interestingly I cannot find any information about this chip. It's not mentioned in the stamdard MCS-4 or MCS-40 documentation.

Edit: I found it in the 3rd edition of the MCS-40 user's manual from 1976
