RSTS on a Pro, was Re: [HECnet] DECnet User Mode Router - Encapsulation Formats - HECnet

RSX would be great too. There was a rumour that somebody got it on a Pro, but I never
managed to get a copy...

I would greatly appreciate RSTS for my Pro380 too if you would like to
share it....

For myself P/OS was never my thing... RSTS would be much nicer on this
box...

Speaking as an RSX fanatic - was P/OS every the right thing for anyone...???
Now, if I could get proper RSX on that machine...

   Urr?  
Doesn't the CNA use an Am7990 "Lance" chip?   As I recall
 that isn't too bad to program.   I must be misremembering what chip
 it uses..? 
 Intel 82586, which has the worst programming interface in the history
 of Ethernet.   It uses a single linked list, which is accessed both by
 the driver and by the chip, without interlocking.   Race conditions
 everywhere... 
        Ohhhhhhhhh, that one!   I remember that chip.   That was an "ie"
     (Intel Ethernet) in Sun parlance.   The "le" (Lance Ethernet) found on
     some machines was far preferable.   I had to write a driver for an Am7990
     for an embedded application a long time ago; I remember that wasn't too
     bad.   I've never really looked at the 82586 at the programming level; I
     just remembered not to try to put too much traffic through them when
     building networks of Sun machines. :)

        There's Linux support for it, for which source code is readily
     available, and I have some earlier Solaris source code which will have
     some code.   Maybe pick through that for some tricks.   But man that
     sounds dangerous, no access clash protection...ugh.

   Umm...are you
willing to share that stuff? =)   I run RSTS 10.1 on
 many of my PDP-11s; I'd LOVE to run it on my Pro-350! 
 Sure, if I can figure out a way to do it reasonably cleanly. 
        That would be great...Thank you!
