Re: DTL logic. I've finally seen some.
I had some of the Norbit Series 1 devices in the late 60's, some flops and gates. They came in red, orange and yellow packages; of course I had to break one open to see what was in them and they had a small PCB maybe 2"x1" with discrete transistors/resistors etc. I have a feeling they were an uncommon type - OC42? OC47?
There was a Mullard or Philips apps note that described their uses including using a wire delay line for serial memory storage.
