As you probably already have thought, XXDP is the moniker for a group of diagnostic packages on various media. TCDP for DECtape media, RKDP for RK disk and so on. Don't know what the D in DDP1 would be.. D0AA seems to be a test suite for basic instruction tests on PDP-11: https://s3-us-west-2.amazonaws.com/archive.pcjs.org/pubs/dec/pdp11/diags/MAINDEC-11-DZQAB-B-D_User_Reference_Manual_Oct73.pdf But you most likely already know this :) /P
