A little fun with SIMH and OpenVMS

VAX/VMS has always been interesting to me. I'm currently a member of the OpenVMS Hobbyist program, so I have a copy of OpenVMS 7.3/VAX.
I decided to run it on SIMH which is an excellent collection of software aimed at preserving computer history through virtualization of obsolete machines.
I must admit that, for me, VMS brings about a bit of nostalgia, since it's where I cut my teeth. Some of the first systems I was ever lucky enough to play with when I was young were VMS systems and it inspired me to learn more and more about software and computers in general.
What I did here uses the latest version of SIMH built for PPC. You'll need to change SIMH a little in order to get it to build on the Mac, the instructions are here. Also, you'll need to follow Phil Wherry's excellent guide on getting VMS installed in the first place, that's here. And, finally, you'll need to get DECWindows installed, that information is provided here.

Here's "Toetag." It's an open source Quake level editor being ported by Eric W.
As you can see he's been able to make a fair amount of progress in a number of things. The NSStepper/NSStepperCell for instance has been improved as well as Font display among other things.
Here's the original website here.

More to come... :)
