brew-your-own-unibus boards?

I missed the first part of this discussion and I just found this message by chance. However it is NOT TTL, it's DCL according to my 1971 Signetics Digital 8000 Series TTl/MSI catalog. Since it's not TTL this catalog doesn't have a data sheet for it but they do have a list of all of their ICs including the DCL ones and it's listed there. They say that it's a

2-input NAND gate and that it's listed in the DCL supplement handbook.
