Which RT-11 for an 11/03

There is no difference in the LSI-11 board on an H-11 and a pdp-11/03.  What DEC did do was cripple Heath's version of RT-11 (called HT-11).  It would only work with Heath's H-27 floppy drive unit.  The Heath serial, parallel, and memory cards were all compatible with DEC's offerings, AFAIK.
That being said, I personally don't have experience with true RT-11 on the H-11.

If I have time tonight I'll log the session with "verbose" set on the TU58EM. 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.
