They are indeed XXDP disks. They're the field service set for a
microPDP-11/23+. They contain XXDP Ver.2 plus relevant disgnostics, the
User Tests disks has the XXDP utilities and confidence test, Tests 1 has
object files and some utilities, Tests 2 has KDF11/BDV11/DLV11J/etc tests,
Tests 3 has less-frequently-used interface tests, Tests 4 has other tape
and disk tests.
