Mentec

Hi, Rod.

Jerome makes some interesting, if strange and faulty assumptions.
Such as assuming that since Mentec hasn't complained although people 
"appear" to have been using and posting about RT-11 on classiccmp list 
for a long time.

First of all, we don't even know if Mentec knows about the classiccmp 
list, neither if they scan it (which perhaps some people should be happy 
about).

Second, I can't remember that many people actually coming out saying 
that they are using RT-11 without a license.

So I would somewhat ignore Jeromes view on the legality of things.

That said, I'll answer some of your questions.

I agree with you. It's fun to actually run the real hardware, and not 
just play with a simulator. Not the same feel of satisfaction. I still 
play with an 11/70 here, even though we also have E11.

That is probably one part of it.
Another part is that they have paying customers (still) and probably 
don't think it's a good idea to start giving it all away for free, which 
means they need to draw up some sort of license that will limit things 
in a useful way. Doing that costs money, and they probably can't see any 
profit from it. So why spend that money?

Yes. As someone who have customers who still buy from Mentec I can 
definitely confirm that they were still selling ten months ago. Can't 
see a reason why they should have stopped since then. This is RSX and 
layered products, by the way.

 > 	2.  Are they still making PDP-11 hardware?

No. I think they stopped manufacturing "real" PDP-11 hardware, and are 
now pushing for emulators. However, that is a grey zone. We haven't had 
a real "true" PDP-11 CPU since the 11/20. All the rest are microcoded. 
Microcode is also software. :-)

That is a really good question, and one which I don't have an answer to. 
But I'd like to know if someone else have.
