[Simh] SimH on Raspberry Pi - out of date?

2016-03-19 Thread Paul Hardy 2
I've been running some VAX emulations on PC and on Raspberry Pi, and I note
that the version of SimH that you get with Rapbian is a rather elderly
3.8-1. What are the plans to get 4.0 be something other than Beta, which is
presumably a prerequisite for it being pulled as a supported package on
Raspbian?

 

Yes I could clone the sources and rebuild a Pi version of 4.0 from github,
but it would be a pain to do on the Pi, and given the Pi is meant to be
friendly to beginners, it would be good to have a pre-built current SimH
available.

Hello!
So do I, but I'm also running Raspbian. It's, ah, causing me to feel
rather peeved. For our other favorite, I typically end up building it
from source We can do the same, but a lot of us would rather use
existing packages.

With Raspbian being based on Debian it's not likely you'll find the latest
versions of anything in Raspbian's repos.  Debian errs on the side of
stability and takes its time with getting the latest versions of packages
into its "stable" branch.  I'm not familiar with Raspbian.  I only have one
Raspberry Pi and I'm running Arch Linux on it.  With regular Debian there is
a "testing" branch that one can switch to to get more up to date software.
Even in Debian's testing branch the latest version of SIMH available is
3.8.1-5.

As long as you stick to a wired connection on the Pi, the non-routable

If you're so inclined, you might open up the VT420 casing and see

plenty of %V power points to feed the Pi. Then all you need is a serial

Very nice.  Do you have instructions or downloads for making that
11/780 case?  It looks like foam-core board and blue painter's tape
covered in printed accents (but they could be hand-drawn... hard to
tell from the photos).  Is it 1:10 scale? (metric) 1:12 scale?
(imperial)

This is a feature of 802.11.  The packet format over the air for 802.11 has two 
MAC addresses in it to in theory enable bridging.  One for the radio and one 
for the sender.  Most 802.11 firmware just stuffs the radio's MAC address in 
both and ignores the MAC address in the original frame when sending, and when 
receiving the senders radio MAC address is used in the frame propagated to the 
computer by the adapter.  The result is that everything is sent as if from the 
host and not the VM and replies are delivered back to the host and not the VM.  
This can be worked around in the hypervisor as VirtualBox does for IPv4 and to 
some degree IPv6.  But don't expect a SimH machines to be able to communicate 
over WiFi without a lot of work in SimH’s networking implementation.

It is. One of the things that separates VMS newbies from us dinosaurs is 
that we treat "Open" in OpenVMS as a silent prefix :-)

Are you documenting the setup process for your endeavors, or just

you clustered those Pi Vaxen as much as to know it was possible. I've 
got a few Pi around looking for something to cluster around...

There are three parts to a successful setup:

1. Since each Pi has only one Ethernet interface, make sure you use a
   wired connection (wireless isn't real Ethernet) and the tun/tap
   setup on the Raspbian Linux host. This is well documented in the
   github simh docs. This will leave you with access to your LAN
   from/to the Linux host, as well as a "separate" tap0 device for the
   VAX/VMS guest.
2. Build your VAX of choice. My three cluster members are a VAXserver
   3900, a MicroVAX 3900 (same "vax" build for simh) and a 16MB
   MicroVAX II ("microvax2" build). The latter because I wanted to see
   whether the MicroVAX II could be configured with TCP/IP at all. The
   build process and its options are -again- well documented in the
   simh docs.
3. Deploy your VMS OS, configure DECnet and TCP/IP and use the
   CLUSTER_CONFIG DCL command procedure to first create the cluster
   "master", and then add the satellites. CLUSTER_CONFIG.COM is sort of
   self-documenting.

I used the V4.0 standard github sources to build, and VAX/VMS V7.3 to 
deploy the cluster. Some Pi's run Raspbian Wheezy, some run Jessie. It 
varies along with my mood and the phase of the moon.


As soon as I get home again (may be in a few days), I can post the

   whether the MicroVAX II could be configured with TCP/IP at all. The
   build process and its options are -again- well documented in the
   simh docs.
3. Deploy your VMS OS, configure DECnet and TCP/IP and use the
   CLUSTER_CONFIG DCL command procedure to first create the cluster
   "master", and then add the satellites. CLUSTER_CONFIG.COM is sort of
   self-documenting.

I used the V4.0 standard github sources to build, and VAX/VMS V7.3 to 
deploy the cluster. Some Pi's run Raspbian Wheezy, some run Jessie. It 
varies along with my mood and the phase of the moon.


As soon as I get home again (may be in a few days), I can post the simh 
ini file(s), my /etc/rc.local which implements the tun/tap stuff, as 
well as VMS MODPARAMS.DAT. That is as far as I will go in documenting. 
Making it work and stumbling along was part of the fun. It is my way to 
teach myself Linux. VMS, I know of old.

Wilm,

Are you documenting the setup process for your endeavors, or just 
blogging about the result? I think it would be interesting to see how 
you clustered those Pi Vaxen as much as to know it was possible. I've 
got a few Pi around looking for something to cluster around...


Thanks,

Will
