Thanks Gary. This is my understanding as well since everything works with XXDP right from DEC and I'm not using the H-27. So, I remain optimistic that I can get this working.

Again, I'm trying the trick of booting from a TU58 emulator and an RK image with DD as the boot target (supposedly can work but maybe slow). I can see the blocks being read in but it stops and doesn't give me the sign-on banner.
