maybe one day I will do great things such as writing code like that:

MOV R3,@(R5)+ 8)


Seriously, I think PDP11 assembler is a very interesting thing to spend some time with. But I am personally not that far yet. In the meantime I got SIMH up and running on my PC. Enough patience to wait until I finally got Hobbyist licenses from DECUS :wink:

Soon afterwards I felt I would need a "real" thing - I could manage to buy a VAXstation 3100 m38 through ebay. Nice box. But 3.8 VUP is not too much when compiling C++ stuff. So I bought another box: a VAXstation 4000 m90 - amazing 40 VUP, WOW! I just love that one. The other box is not completely forgotten - to build up a cluster will be one of my next tinkering experiences smiley

The emulation on the PC is also a very interesting aspect for me. The ~20 years old hardware will die sooner or later, no doubt. Emulators will live on for a while...
I do not have DECs VUP benchmarking suite. From some simple tests I assume that SIMH/VAX on my state of the art notebook (1.6 GHz Centrino) must have around 7 to 8 VUP (its about twice as fast as my VAXstation 3100 m38).

Does it make any sense for a hobbyist to even think about the purchase of the Charon-VAX software? I dont have an idea about its price (why do they make such a secret of their prices???) and I wonder, if Charon VAX will outperform SIMH/VAX in terms of a magnitude, or if it would be just SOME faster.... :?:

Kind regards

Michael

there is a free version of CharonVAX. I don't know if it is quicker than SIMH or not.

I did benchmark latest Charon VAX demo and latest SIMH with calculate_vups.com.

[code:1:fdd210fc27]
Host platform:
Software: Windows
Hardware: Intel PIII-600
Results, VUPS:
Charon: 3.8
SIMH: 2.2
[/code:1:fdd210fc27]

Charon VAX definitely outperform SIMH by performance. However, demo version of Charon VAX have no "Accelerated CPU Emulation (ACE)" feature. So performance of commercial Charon VAX Plus will be ever greater. I know nothing about Charon VAX prices, but surely price will depend from set of purchased features and from product type. Charon VAX licensing is very flexible. It allow restrict maximum number of emulator instances, number of utilized host CPUs, etc.

[quote:512bd5f789]P.S. I have successful experience in extending of purchased Charon VAX feature set[/quote:512bd5f789]

You better delete that statement from this forum as fast as you can! I will delete my quoting as follow up. This is a promise!

For me it is still strange why Charon makes such a secret of their prices. I asked several people, got several "it is REALLY expensive" answers, but still have no idea about their prices...

So what. I'd rather spend some money to support SIMH development. Personally I ended up with a "real" machine: a VAXstation 4000-90. Very close to the upper end of small size VAX performance. And still some years ahead of simulated VAX performance.

"Expensive" is a relative. A production system can have downtime costs of thousands to millions of dollars. I've seen customers who are paying $10,000 per *month* in hardware support. CHARON-VAX provides high value for those customers.

I fly airplanes for fun. Spending $50-$100 per hour of flight time is part of my hobby. Expensive? Depends on your perspective.

If you want a free CHARON-something, you can download PersonalAlpha from the SRI web site and use it for free. IF you're going to play around with VMS, might as well be at version 8.3 instead of 5.5. You can get free licenses from DSPP or the Hobbyist program.

The "price" isn't secret as much as it depends -- there are low-end VAXstation replacements (one with only 16 MB of RAM!) to a 6-processor VAX that's faster than any physical VAX ever built.

I'm a CHARON reseller, and proud of it. My goal is to preserve VMS everywhere I can, and if I have to emulate the hardware, so be it.

HPE only makes the most current version of OpenVMS Alpha / IA64 /VAX available to hobbyists. When I had access to the Alliance 1 program it was the same. No public downloads are allowed by HPE.

lation/ For the most part just use VMS 6.1 media instead of 7.3. But why run the older release?

The openvms disks question is frequently answered in the forums, and is not something to ask about in the shout box.
