Pin 1 is not connected on the MC1408 and does not need to be connected on the DAC08 either. All other pins are used.

As for the DAC, in the KLM-267 board I have its a MC1408.
I also received a new DAC chip from Newark Canada (that's where I am), and it's the DAC08-CPZ from Jed's KLM-367 clone board parts list.
One thing I noticed though is that in the clone board IC-33's pins 7 & 8 are connected, whereas
in the original KLM-367, pin 8 is floating.
