[Simh] Ultrix 1.0

I had success booting the Unix Archive's floppy distribution of Ultrix 1.0 on the MicroVAX 1 simulator. It appears that the distribution there was only meant for a dual-RX50 MicroVAX 1 with an RD drive, and will not boot on any other machine. RQ0 needs to be an RD51 or RD52, and RQ1 and RQ2 need

[Simh] Standalone boot on vax8600?

How are standalone programs loaded and run on the 8600? On the 7x0 I can do "load -o boot 0" and "run 2" and that will run a standalone boot. When I do that in the 8600 sim I get a newline and then the program just loops forever. Alternately, does anyone know the right way to load bootblocks on

[Simh] 4.2BSD with networking on a VAX 11/780

Hi all, As part of ongoing efforts with a different project I set up a 4.2BSD install on a vax780 sim with networking support. After I did it I realized that I wasn't sure it had ever been done on SIMH before, so I wanted to let folks know that it's possible. All I've tested so far is the ftp cl

Re: [Simh] Booting the vax750 simulator.

Out of curiosity I tried Ultrix 4.3 and 4.5 on the /750, both with genvmunix and a custom kernel, and both showed the problem. Whatever the issue here is, it appears to never have been fixed. I tried disabling just about every device I could save for the disk, and I still got a panic every time.

Re: [Simh] Booting the vax750 simulator.

I took a quick look at this under Ultrix 4.3, where the same problem occurs. There are Ultrix 4.3 sources, so that makes things somewhat easier. The panic occurs in ubarelse(), which releases uba resources. Unfortunately, as far as I know, the Ultrix linker does not have a way to produce a link

First of all, thank you very much to Mark for finding and fixing the uba problem with the 750. Glad that modern Ultrix now works on that simulator. Now for a new 11/750 issue: Ultrix 1.1. Before the most recent fix it didn't even attempt to boot, and I just figured that bootloader/OS support was
