I'd like to understand how the vax device drivers and system internals operate at the most basic "primitive level" . just for fun ;) And how the simh commands relate, so that I can debug my low-level experiments. E.g. what I need to Deposit where to do I/O with the various devices. I.e. how it compares to IBM 370 /390 (io / channels SVC interrupts etc) I have the BSD ver 7 source, with the sys directory looking like the most interesting.

Re: [Simh] vax780 bare metal - rq addresses --> rq registers
Oh, and yes, there might be issues with 32 bit access, since the Unibus is only 16 bits wide. Also, you might need to enable the Unibus adapter before you can get to anything sitting on it. I can't remember the details, but the documentation for the Unibus adapter (DW780) is also on the net, so you just have to look it up...

It's a little complicated, because the controller is on the Unibus, and the Unibus only have an 18-bit address space. So the SBI Unibus adapter contains a mapping between the VAX address space, and the Unibus address space, and the UBA also contains mapping for DMA, which must be set up before playing around.

[Simh] Distribution sizes
SIMH is very small no bloatware there. VAX/VMS distribution DVD is under 600MB. Running VMS systems with many layered products (FORTRAN, BASIC-PLUS, DATATRIEVE, UCX (TCPIP)) takes significantly less than 1GB. VMS on ALPHA is also very compact. Sincerely, Robert F.

Ok thx. Ya I put "personal learning" On a related note, do you guys know of a cheap shared 'nix hosting service where I can run Openvms ? I have a free account on alwaysdata.net at the moment, and will look into their paid options. Eventually I will run it on my own box but I have a very slow connection right now, and I'm guessing the download is (relatively) huge (how big is it ?)

Re: [Simh] OpenVms on SIMH - which license ?
This is off-topic here, of course, but AFAIK there is at least one Itanium simulator that is apparently good enough to run at least Linux and NetBSD. It's called ski and a semi-maintained fork of it can be found at https://github.com/trofi/ski . An overview of the Linux booting procedure is at https://trofi.github.io/posts/199-ia64-machine-emulation.html . I have no idea if this can be used to run OpenVMS; perhaps someone with an OpenVMS-Integrity license and a bunch of free time might try?

Re: [Simh] OpenVms on SIMH - which license ?
Mike, I think for SIMH you only need VAX, but I got VAX/ALPHA as there are Alpha emulators around. "Integrity" is for Itanium and I can't see an Itanium emulator appearing soon. Make sure you fill in the box that says what you are going to use it for. Its marked as "not mandatory" but I have seen reports that if you don't they don't send a licence.
