Whanted to get a openvms dev enviroment, where could use it to learn the basic command's to get feel for it without worrying about breaking anything.
So whanted to know if its possible to install a openvms iso image in Virtual Box
In case its possible where could get a openvms image or needed first to get installation cds and from those generate the iso?
if the cds are needed is there some online store that can be bought or the price is only afordable for companies?
only making inqueries to see if its possible and feasible, other wise gona give up the ideia of having a development enviroment.
Well what do you know so far, and what do you have so far?
Do you know that OpenVMS has a 40+ year history, was originally written for the (32 bit) VAX platform, ported to 64-bit Alpha (30+ years ago), then ported to Itanium and X86 (64 bit).
That X86 port will boot natively and you may want to ue VMware, Virtualbox or similar - within the current constraints and offeringg - visit vmssoftware.com for details.
For initial learning I recommend to just to use an Alpha or VAX emulator.
Those could run on a virtual machine, but there is no good reason.
Just run as process on whatever laptop/server your have running Windows (and some Linux options I think).
There are are several emulators out there, both free and commercial - google is your friend.
I happen to like/use FreeAXP for Alpha running under 64 bit windows - just Google.
There is no Itanium emulator.
Do you have access to the software distribution somehow?
For starters, why even bother trying to get your own system?
Just timeshare to get a feel for it.
For example SSH to decuserve.org [184.168.131.241 - ooops: 104.207.199.162 ] - ask for an account - presto!
Other timeshare options are available - and very valid to learn the basics (file system, editors, compilers,...)
Good luck!
Hein.

Ok so, my monitor is going black on random occasions. Mostly it is when i watch a video. It doesn't matter if it is on youtube, facebook, udemy or whatever other site.
I checked my cables they are all good. I also turned off the screen saver.
Any ideas what it could be?
there could be many reasons for this - bad drivers, bad cables, bad screen, GPU overheating and melting solder connections (I've experienced this).
the easiest thing to check is to see if the issue is in the computer itself. to do that, connect to a different monitor (using a different cable).
to check if it's a software issue, you could try running a LiveCD of a different OS on your computer (for example, Fedora or Ubuntu).
if the issue still happens even with a different OS, then it's likely a GPU problem - you'll need to either get that replaced, replace the mainboard (if GPU is integrated), or replace the computer...

I've read that every manufacturer can produce his own BIOS ,
where to find a specific BIOS interrupts list , and how to know my PC's BIOS version?
there's a lot ( IBM , AT&T , ..)
And it's really strange that the only reference is RBIL !
where to read "ALL" interrupts of specific version ?
Most BIOS vendors are compatible with the original IBM PC BIOS source, but that is a convention, not a rule. Many BIOS vendors will offer their own extended/undocumented BIOS calls.
If you are simply trying to boot, read disk sectors, print characters on the screen, etc, you should be able to manage that without having to know which specific BIOS you are running on. After all, they must be similar enough for DOS to boot!
If you really want to know what specific BIOS you have, you can look in the BIOS POST or setup screens. Look for a version or ID string. Otherwise, you can boot Windows and run the System Information tool, which can tell you. Otherwise, you can dump the F000 segment to a file and run the "strings" utility on it. Again, you probably do not need to know this, because it is irrelevant for 99% of the basic PC operations.
My favorite reference for BIOS and DOS interrupts is the Programmer's PC Sourcebook (Second Edition). It's long out of print, but I think you can still find used copies on Amazon. There are other books out there, but this is the one on my bookshelf that I have used for the last 10+ years.
If you are adverse to spending money, the Ralf Brown Interrupt List (RBIL), seems pretty comprehensive, but I have never used it personally.

Just got myself a new Windows 8 tablet, which operates a 32 bit Win 8 (It was advertised as 64 bit on amazon, but that's another subject I guess).
My question is, can I upgrade the existing system to 64 bit, without having to set up win 8 again? I haven't found anything on google, not even someone with the same question which makes me kind of afraid there is no solution.. Anyway, here I am and ask :)
Any answers are kindly appreciated ^_^
There is no upgrade path when changing architecture, so no, you will have to do a complete reinstall when switching from 32bit to 64bit, no matter what hardware you are on.
Your data will be lost if you do not backup manually, all programs and drivers will need to be re-installed.To quote Microsofts official documentation:
If you want to move from a 32-bit version of Windows to a 64-bit version of Windows 7 or vice versa, you'll need to back up your files and choose the Custom option during Windows 7 installation. Then, you'll need to restore your files and reinstall your programs.

first of all - thank you in advance for all answers.
Second - I'm not asking about writing console programs working on modern systems (like Ubuntu 11.10 or Windows 7) nor batch files.
Third - I'm not going to become DOS 6.22 nor Windows 3.1 programs developer. Maybe I will write small program only for educational purpose.
I am wondering how programmers works on early (I refer to 70's, 80's and begining of 90's) days of computer. On wikipedia there's many information about, let's caled it "ancient times", but there's not enough about "middle ages" (I'm referring to 70-90's) in programming definition. Although in DOS times programs higly depends on used machines (because they directly call hardware IRQ), I can't believe that there wasn't something like today Integrated Development Environment and that some of them were written in high level programming language. Is it possible that Prehistoric 2 has been written in Assembly? I don't think so, but I assume that early versions of BASIC can't receive such possibility.
Could you recommend any good article or source of information? I'm interested both MS (DOS, Windows 16-bit) and Unix platforms.
See also Borland Turbo C++ and Borland C++, commonly used in the early 90s.
If memory serves, Commander Keen was built using Borland tools. It's probable that other same-era Apogee/id games (like the original 2D Duke Nukem) were built under Borland as well.
Later on (early-to-mid 90s), id Software started using Watcom and the DOS/4GW DOS extender to build games like the original DOOM.
I was working in that period on Windows 16-bit and DOS (also DEC VAX and Alpha).
Mostly I used Turbo Pascal and Delphi 1 both of which provided IDE's. This was in the early 90's

I'm trying to figure out the best lower-budget home office development hardware setup. My laptop is aging.
My latest idea is that I would like a very powerful desktop paired with a less-powerful laptop. The idea being that the desktop would do the heavy lifting while the laptop would allow me to work untethered (but within range of the wireless network, of course.)
Is such a thing possible, or am I dreaming?
(I develop .Net applications - mostly Asp.Net)
Thanks for ideas!
You can do that with an RDP / Terminal Services client or VNC. You could also run multiple virtual machines on the beefy server (making it look like a poor man's datacentre / set of less powerful servers).
Another benefit is that you can do some testing with the laptop as the browser client and the desktop as server - this can sometimes show up issues that you won't see with testing on localhost (especially if your network goes down in the middle of it).
Yep, this makes sense and this will work. It's a similar model (but not the same) that's been used for unix workstations in the past (X window).
I would keep your aging laptop to use for testing thin client apps - who cares if it's aging how much power does it need to run Internet Explorer?
My dream development system at this moment in time would look something like this:
A couple of nice fast dual core processors
4 Gigs of memory
A couple of Intel X25-M 180Gb Solid State Hard Disks to run my apps off.
3 x 19+" high contrast ratio monitors, these 3 I have on my desk are wicked.
Ergonomic keyboard, I currently have the Ergonomic Keyboard 4000 which I quite like
Wireless Laser Mouse, I currently use the Logitech MX Revolution and I love it
A 2Tb SATA drive for extra storage space (just in case)
Of course, I don't have any of this at home, I have an aging laptop just like you. I have part of this setup on my desk at work and I keep drooling over the other bits and pieces.
You can use the desktop as some kind of a server and let both your desktop and your laptop compile.
It's like they render 3D CGI movies in studios, across a farm of computers.
This is exactly how my current setup is, and it works nicely. I'd still get a couple of 20"+ monitors, as the laptop can be a little restricting for long usage.
