Hello! What about it? On my system it looks for the tell tales that are found on the currently popular virtualization flags found on both Intel and AMD processors, and crashes when it can't find them. It wants me to find them in the BIOS. I tried to do that eight years ago this weekend, when the

Hello! Probably a VM, but that's as far as I've gotten. It really depends on how the software reacts to running inside it. Some of the surviving examples of software we have available just won't run inside VirtualPC for example, but will just barely do so inside VMWare. - Gregg C Levine

Re: [Simh] TE16 CRC Errors

I actually don't think he has a mixed massbus. I don't think you could even configure simh for this. Simh have a very simplistic view on hardware configurations. You don't configure massbuses, and put devices on them. You normally just configure the devices, and all the bus and controller

[Simh] TE16 CRC Errors

Peter, My reading of your hardware setup sounds like what was called a "Mixed-MASSBUS" configuration, that is, mixing disks and tapes on the same MASSBUS. PDP-11 RSX-11M-Plus supported Mixed-MASSBUS. We dual-ported all our disks and used the MASSBUS that came with our tape drives that way.

Re: [Simh] Attach tar to tape device and access it from v7 in simh

The original V7 tar was not quite graceful about directories and that image was probably not written by an original V7 system. The directory issues were fixed quickly. You need a new tar, such as the one from 2BSD to read that tape without error messages, although I suspect the original will

You need to convert the foo.tar file to a foo.tap before simh's mag tape reader will understand it. If you want to skip that step, attach the foo.tar (or foo.tar.gz) file as a virtual disk. The open it as a raw device. Clem On Tue, Nov 7, 2017 at 2:58 PM, Will Senn wrote:

I am running VAX 3.8-1 on a 64-bit Linux system. It performs well with OpenVMS as the operating system. But when I try to run it with OpenBSD 5.7 there are issues. The base system installs and boots correctly. But in order to bring in tools such as language compilers or editors, it is necessary
