Which RT-11 for an 11/03

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.

I haven't used V3 (I have some RX01 flopppies with that and MuBASIC) in several decades so I can't remember if that was when it changed. But for all versions you need to set up the correct boot block for the specific boot device. 4.0 is so straightforward I'm surprised if it won't run on Rich's H11 - 4.0 is contemporary with the LSI-11 and 11/03 and although the other cards are different I thought the H11 used a standard DEC LSI-11 processor.
