2233.0. "VT1000 graphic and MB dependencies?" by CSC32::R_BRADLEY () Thu Feb 08 1990 12:32

    
    
    	After skimming the SU article announcing the VT1000, I have a
    question concerning its memory availability and capability.
    
    I am a software specialist at the Colorado Customer Support Center. 
    These new terminals are being discussed among other fellow specialists
    as possible "workstations" in lieu of VAXstation 3100s.  Most of us
    only require the multi-windowing capability
    
    The question...How many simultaneous windows can be supported by how
    much onboard memory?  The SU article says 1 MB for text oriented
    applications.  For graphics and text the recommendation was a minimum
    of 2 MB.  Most specialists typically have three to four terminal
    sessions active at one time and most sessions are text-oriented. 
    However, in the future, there is the possibility of graphic-oriented
    windows ( Bookreader, etc...) being the common interface for a given
    specialist's day-to-day tasks.
    
    Is 2 MB enough for future graphic-dependent applications or should we
    just go all out with 4MB?
    
    Thanks,
    
    Rick

I wonder if this conference is really the best place for questions on the
VT1000 terminal, since DECWINDOWS is intended for discussions of the
DECwindows software.  I might suggest HANNAH::TERMINALS as a better location.

    Ah, the VT1000 terminal is a hybrid terminal/X-terminal capable of
    both standalone ANSI terminal operation and networked X11 display
    capability and is properly discussed under the heading of DECwindows.

RE: .1 - I tend to agree with you Steve, this notes file could eventually be
renamed to DEC, since everything in DEC relates to DECwindows these days. If
this notes file supports every product, both HW and SW that relates to DW, then
everyone is going to spend much more time looking for information.

Perhaps, however, I can end the replies for this note by saying I have a DWT for
testing in Germany. It is running X4.3 reve level of roms, which I understand
is about 8-11 weeks old. I don't exepect, however, for memory-related actions
to change much between my version and the final production model.

From my observations, 2MB is minimum. The unit starts out, after booting the
Xserver and terminal(session) manager consuming about 700K. (This might 
increase or decrease depending on (future)optimized code for space or speed)
So, this leaves one with ~300K left if one bought the "bargin basemet" model.
I am sorry to say that 300k won't cut it for one LAT terminal. It *might*
do it for a terminal using either the printer or terminal port. However, if
you're in a large DEC/VMS environment with LOTS of LAT traffic (services) all
in one area, then you'll find that if you try to use the thin-wire port
to connect, using a LAT connection, 300K won't do it. I've also found the
same to be true using a TELNET connection.

Someone from the VT1000 group might disagree with me, because they might have
found a way to do it with 200K. But I find that you want to keep about 50-100K
free or else it hangs (keep in mind I have a pre-fT version).

Another reason I would recommend to customers to buy 2MB minimum is because they
will then have the memory expansion board already installed. They then, could
buy any remaining SIMMS on the open market for MUCH less than the $600 MLP
DEC is charging. (The going rate is about $100/MB)

Now, Do you need MORE than 2MB. Well, I for one don't think so. It mostly 
depends on how many OUTBOUND terminals you run, and how many INBOUND Xclients
you have running (and what/how they display). I find I can run two DECterms,
DECW_QUOTE, Bookreader, Calendar, and DECwrite and still have 800K free. I
have a 2MB version. If I didn't want VT330 emulation, and wanted printer port
features, then I would use more OUTBOUND terminals, and this would consume
more memory. I would estimate that 3 MB should be a suggested value for 
customers who want to do a lot of OUTBOUND terminal connections to many diff-
erent nodes that are unable to run a DECterm, or who might need the printer
port feature. 

I can't ever see the need for 4MB. Even the PC folks have found this to be
the case with their server.

Hope that helps. If I can ever get the damn x11perf program to complete its
tests (the DWT hangs about half-way through) I will post the results if anyone
is interested.

Cheers,
-Ken

I also have a VT1000, with X5.1 ROMS and 3MB of memory.  I have yet to see
the free memory drop below 2MB, even with some pretty complex screens
and graphics displayed.

re: X11perf

I know that it is easy to run X11perf and publish the results, but I think 
it is appropriate to allow the group that owns the particular box and X
server to be the ones that do this.  Only that group knows what performance
work is left in their workplans and when and where they expect things to
improve.
2233.6GERUND::WOLFEThat's a 511 ma'm. Failing to yield to good tasteFri Feb 09 1990 20:239
    I have 3 Mb and X5.1 roms. Just for grins, I invoked DECwrite and
    brought up every single dialog and subdialog box (~90 boxes). I was
    left with 125Kb. This is a completely unrealistic use of DECwrite of
    course. However, a customer running DECwrite, DEChart, and DECdecision
    could apporach the memory limits of a 3Mb DWT. Applications like
    Paint also take a large toll on local memory. In general, 3 Mb seems
    adequate for most needs.

    Please do not direct general queries about the "VT1000" to the
    HANNAH::TERMINALS  conference.  That conference is dedicated to
    discussing traditional terminal products and their use in Digital
    systems.  I am unaware of any other forum available for general
    discussion of the alleged product.

2233.8Windows on PDP-11's?AOHM::JACOBSRemember the FutureThu Feb 15 1990 13:437
    Does the VT1000 support Windows locally or must the application on
    the Host system support windowed applications? What I am trying
    to determine is if we could use the VT1000 on a PDP-11 to run multiple
    processes in DECterm type windows. 
              
    Thanks

Sigh - I wish there was a VT1000 conference.

The VT1000 can operate in several fashions.  One, it can talk to an X-windows
client.  Two, it can create DECterm-type windows using the serial LAT protocol
or TELNET protocol over Ethernet.  Third, it can create DECterm-type windows
over serial lines (it has two, one considered a "printer port").

So if the PDP-11 system wasn't an X-windows client, you could still use the
VT1000 as the equivalent of several VT320s in one box, assuming the use
of LAT or TELNET.

Please go find the Sales Update issue that announces the VT1000 and read it.

Why not ? seems to me that the VT1000 does not fix 'well' into
here or the terminal conf

Why not its own conf ?  (which would be fairly busy.. I think
			there's going to be a lot of interest/questions

Re: .10

Apparently, the people in the group that have developed the VT1000 aren't
eager to start a conference for it.  I'm just a field-test user.  (Though
I started both the MICROVAX and VAXELN conferences under the same
circumstances, I'm not willing to do this again!)

    This conference is intended for discussion of the VT1000 DECwindows
    terminal.
    
    Please note that the conference is *not* owned by the VT1000
    engineering group. I created this conference here to fill a perceived
    need amongst the Easynet community. Therefore, you shouldn't
    necessarily expect any definitive answers to questions asked here. With
    any luck however, enough knowledgeable people will read the conference
    to make it useful.
