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. -------- Original message -------- From: Richard Cini Date:03/10/2016 4:09 PM (GMT-05:00) To: "General Discussion: On-Topic and Off-Topic Posts" Subject: Re: 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. Rich Sent from my iPhone
