DECnet-VAX Phase V P.S.I. configuration in open_simh

The addition of HDLC framing support to the DUP11/DPV11 devices in open_simh extends the number of networking products can be used under VMS in the simulator.

The most obvious product to demonstrate is VAX P.S.I., which provides X.25 connectivity.  This example uses P.S.I. in its simplest possible mode, with two systems connected back to back, one configured to act as a DCE (X.25 is asymmetric). 

P.S.I. is shipped as part of DECnet-Plus, so if you chose not to install it originally, re-run "PRODUCT INSTALL" for DECnet-Plus, and answer yes to the question about installing P.S.I. The rest of your configuration will remain unchanged.

A valid license for "P.S.I." is needed to get started.  

If you're feeling confident, you can just run @sys$manager:psi$configure and go through the configurator, to produce your own startup scripts.

To avoid needing to run the configurator, and just use the example scripts below, do the following while logged in as SYSTEM:

$ set def sys$system
$ mcr authorize
add /id psi$open_security

$ create sys$startup:psi$configure.ncl
$ create sys$startup:psi$enable_decnet_clients.ncl

The following example shows the open-simh and VMS commands required to set up a second DUP11 device, which I needed as I wanted to continue to run DECnet at the same time. You can obviously do it with just a single device if you prefer.  Whichever, you will need the patched SEDRIVER mentioned in earlier posts.

The configuration files for each end are almost exactly the same, but one end needs to be a DCE, and also has a different address.

DECnet-VAX Phase V WAN connectivity with simh

Installing VMS and DECnet-Plus HP's VMS Hobbyist program used to make the VMS 7.3 distribution CD available as an ISO image file. While there is no longer an official hobbyist program, I would imagine that the CD image is findable if you look hard enough. Once in possession of an image of the VAXVMS073 CD, you can install it using your simh configuration of choice, which must have a Qbus or Unibus.  There are plenty of examples out there to help with VMS installation, but if starting from scratch, you boot from the CD; use standalone backup to expand saveset B onto your normal boot medium, then boot as normal and go through the installation dialogue.  During the installation you should choose to install DECnet-Plus (aka Phase V). Here's an example:  https://raymii.org/s/blog/OpenVMS_7.3_install_log_with_simh_vax_on_Ubuntu_16.04.html To make the system fully useful, you'll need a valid license loaded for at least VAX-VMS and DVNETEND (endnode) or DVNETRTG (router).  O...

Time Electronics 9814 IEEE-488 Interface testing

Image
I mentioned in an earlier post about this instrument that I might try to get IEEE-488 working with it. I'd naively assumed that one could simply search on eBay for "USB to IEEE-488 interface" and pick something up that would have an open source Linux driver for about £10.  I was slightly surprised to find that the new price for such an item was actually over £1000, which I suppose just demonstrates that IEEE-488 was never used outside of labs, and as such, why leave money on the table by making it cheap ? Anyway, it turned out that there's a very nice  Arduino project  that just needs a cable to be wired up, so I thought I'd have a go at that since I had a Mega in the cupboard. AliExpress obliged with a cheap cable that I could butcher, and I set to work with a set of pins and some crimping pliers After a bit of crimping, sorting out the wiring diagram from the AR488 manual, and full checking for connectivity, I had this mess The AR488 software needs some minor co...

Ubiquiti Edgerouter ER-X Flash issues (free space, hangs, firmware upgrades)

  The ER-X is a very cheap 5 port router, with a lot of enterprise-level software features. It's almost too cheap, because it doesn't really have enough Flash memory, and certainly with earlier samples, the Flash itself was rather unreliable. For a start, there isn't enough Flash space to store three images, so when you want to upgrade the firmware, you always need to delete any old backup version that's still installed to make enough free space ("delete system image" CLI command). The firmware upgrade process ("add system image") itself can be rather hit&miss on devices that suffer from unreliable Flash, requiring multiple attempts to succeed. The symptom I found is an apparent hang at the "Copying Image" stage, with a crash and reboot after a few minutes. There are many reports on the Internet of ER-X having random hangs with various software versions, in particular there's a symptom where IP forwarding seems to work normally, but...
