I will try that but I doubt it'll make any difference. The cisco autodetects 100/full on both of it's virtual interfaces. The AlphaVM-free link to the localhost loopback also comes up 10/half.
Is it actually throttling it to 10/half, or is that just a side effect of the card it emulates?

Have you tried "duplex full" under the "interface" section in your emulated cisco?

Running a virtual cisco 7200 with a tunnel into my "real" router doing decnet routing.
I have HECnet connectivity from the alpha! :)
$ set host 1.13
Connected to "MIM "
However, when I start DECnet I get this message:
%EWA0, Half Duplex 10BaseT connection selected
I mean, performance isn't terribly important, but I'm just curious if there was something I could do to change that. Emulated adapter on the 7200 is FE, so I wouldn't mind at least that.

Has anybody tried to set this up? I think it'd be nifty if we had say Hercules with MVS connected to HECnet..
If I ever get off my ass and get on HECnet, I might even be able to hook a real mainframe (at least part of the time) to the network.
Oooooh! What mainframe? ;)
Peace... Sridhar

Maybe so. Then again, PL/1 is essentially a hash of Cobol and Algol stirred by 1000 monkeys, so since both its ancestors fit in a PDP-11, PL/1 presumably could also. For that matter, IBM had one on the 360 that ran on a 128 kB 360/44, so the job could be done in a PDP-11 class machine.

Don't think I've ever seen one. I have F4, F77, Pascal, BASIC+2,
COBOL, BCPL, Simula-2, Xlisp, TECO, Forth... Possibly some other
things that I can't remember now...
Right -- Cutler did the original PL/1 compiler for the VAX only. He
bought the front end from Frieberhouse (aka LPI aka Liant - aka
Ryan-Marfarland). Since it was written in PL/1, Dave had to do the
development at MIT on Multics until it was good enough to could self
host on the VMS. At the time, there was not market need for an PL/1 for
the 11 family and if my memory serves me, I think the development for
the 10's and 20s was going away. PL/1 was IBM's big systems language
and they were trying to move their code base from FORTRAN and Cobol to it,
As for the PDP-11 C compiler generating poor code, that's because it did
not really have too as the feeling was that the Ritchie compiler for
UNIX was not that good either. Any C compiler of the time was viewed as
just needed to work properly, self host and generate correct code. For
the users of DEC OS, folks tended to write in FORTRAN or Macro on the
11s (or BLISS if you were DEC - but you need a 10 to cross compile).
[...]
The PDP-11 C compiler is a much later product than any of the stuff you talk about here. It's something DEC did in the 90s.
As far as I know, Cutler left the PDP-11 scene back in 1974 or so. And while there, he did kernel stuff. He was not involved in any compiler stuff back then as far as I know.
I've never seen the insides of a PL/1 compiler, but I bet it would take some work to get it to fit on a PDP-11... :-)

This explanation is insanely helpful! That's what I love about this mailing list.
THanks for the education :)

i.e. one equal sign is for the local symbol, two equal signs are for the
global symbol, and the local takes precedence over the global.
To delete a symbol: DELETE /SYMBOL
