I do have "Security DELTA Data Access Card". However you still need White Punch Card to obtain the schematics! Taken from the comments on the link you gave:
"This item permits engineers with the otherwise required skills to learn the Discombobulator Ray recipe from the Matrix Punchograph 3005-B, as well as learning the recipe for the Minor Recombobulator from the Matrix Punchograph 3005-D. Note, however, that having the associated punchcards is still a necessity to access the punchographs."
As far as I remember, on retail, you did need the punch card and the delta card to learn the schematics. Perhaps here you only require the delta card. I will do a stealth run of gnomer and report back.
Edit: Well, I just got them. Not sure if I was plain wrong that u needed the punch card or if you needed it in another patch but apparently you only need the delta card. I feel so stupid right now.
Thanks for the help guys, without you I prolly would never gotten the schematics
