Re: [Simh] XXDP v2

I did a quick hack and removed the clock from the device list, effectively disabling it. With that done, the 11/23 runs XXDP V2 correctly, with 64KB of memory. I'll add BEVENT DISABLE to formalize this. So the failing systems are the 03, 04, 05, and 20. Possible common factors: - no memory

Hello! My mistake. What lives on IBIB isn't 2.3 its 2.5. And their FTP service is playing games again. I found it by using Google. And it showed me the HTTP crawl for the pages. - Gregg C Levine gregg.drw...@gmail.com "This signature fought the Time Wars, time and again." On Mon, Dec 28,

Re: [Simh] XXDP v2

It's the MMU. After adding the BEVENT disable logic, I noticed that the MMU option cannot be disabled in any model, although it was in fact optional in the KDF11A module (but not the 11/23 system). So I hacked the configuration table to make the MMU optional and tried an 11/23 with no MMU. It

Re: [Simh] XXDP v2

The "2.2" image on ibibilio is actually XXDP+, the "V1" monitor. It runs everything, including the 11/03 and 11/23 with BEVENT enabled. The 2.5 image runs on the 03 and 23 with BEVENT disabled, as well as the 04, 05, 20; in effect, everything as well. So the problem occurs in Mattis' XXDP 2.2

All, I have posted a new blog entry in the form of a tutorial on setting up and using RT-11 v5.3 in SimH. It is accessible via: http://decuser.blogspot.com/2015/12/tutorial-setting-up-rt-11-v53-on-simh.html I am aware of and appreciate the extant tutorials, but I have found them lacking

Re: [Simh] Strange PDP-11 behavior

Ah... And I need to correct myself. Bob didn't say that the 11/23 didn't have an LTC. He said it didn't have a LTCR... So, in short, you cannot disable the LTC interrupt on the 11/23. Interesting. Weird. Oh well. I can't find any reference to an LTCR in the documentation, so it would appear
