Sorry, for the confusion regarding half words and file formats... I don't
where the half-words came from...

Anyway, I am now able to spend time working on this to figure out where
I went wrong.

FYI, There is a document that has some details regarding RMS that I used
to figure out things.

it is at: http://daviddeley.com/programming/docs/rmsinternals.htm

thanks again and sorry for the confusion.

For each line there is a 2 byte length, 2 byte line number followed by the data 
bytes... One more thing is that each line is halfword aligned with padded null 
bytes.

Thanks... Is there any way to change the file attributes to match the var 
records? When I unzip the files on vms the length bytes show up as characters.

This is just for my future info, I wrote a Linux c program to doe the 
conversion.

Thanks

[Simh] Help with loading vax82b zip file into simh/vms

2019-04-04 Thread Ron Young
Hi All:

   I want to load some programs from the vax82b decus "tape" into my
   simh/vax/vms 7.3 system. VMS is installed and running.

   I normally would download the tape image and mount it in simh/vms and
   copy/restore. Unfortunately, I can't find any tape images for vax82b.
   There are zip files located on
   https://eisner.decus.org/repository/master/vms/library/.

   However when I ftp the files over to vms, the record type is messed up
   (displays 2 bytes of "garbage" and doesn't see the end of line). Looking
   at a linux dump of the first couple of lines (shown below).

   Any ideas on how I can fix this, or where tapes images are located?

   thanks

[Simh] how to set language number for VAX VMB

2018-12-15 Thread Ron Young
Hi:

I'm playing with the latest version of the microvax 3900 and
4.3BSD-Quasijarus0c and would like to set default language
in VMB to 5 (us english). If I remember correctly there used
to be a "set language 5" command to do this on real hardware.

Any idea how to do this on simh?

[Simh] dhcp client for openvms 7.2 (hobbyist cd)?

2018-06-07 Thread Ron Young
Hi:

Is it possible to config the hobbyist version of openvms (7.2)
vax to be a dhcp client for tcp/ip.

I have been using my vms install for years with a static IP
without problems.

Looking on the net, it looks like I should be able to do this
if tcpip is version 5.3 or newer. This references a binary
called tcpip$dhcp_client.exe. This file is not on my system.

how do I determine what version of tcpip services am I running?

is it possible to configure dhcp client on the hobbyist system?

thanks

Hi:

I interested in playing with the CP-V system on the sigma simh
emulator. Does anyone know if there is bootable software kit
available?

There are several tape images stored on bitsavers, but they
don't look like there is a bootable system tape.

The stuff that I found on bitsavers is:

[Simh] how to request openvms hobbyist license paks

2017-01-19 Thread Ron Young

Hi:

I've been trying to get a new set of license pak for hobbyist
use with simh vax/openvms. I seem to going down the rabbit hole.

For the last several days, all of the links that I tried either
end up with page not found errors, or no response.

The latest one I found from http://decuserve.org provides the
following two links:

https://h41268.www4.hp.com/live/index_e.aspx?qid=24548&design=cs

(gives 404 page not found)

the other link accepts the request form but I haven't gotten
any response...

http://plato.ccsscorp.com/hobbyist_registration.php

Any suggestions?

[Simh] how to enable tc11 (was Re: RT-11 source)

2016-10-24 Thread Ron Young

Hi:

I'm interested in reading the dta images for the rt-11v2 source.

Question: How do I enable the tc device in simh? I'm running
the latest  PDP-11 simulator V4.0-0 Beta git commit id: c9af9a70.

I've tried changing the cpu type, but still can't get the TC
device to be enabled.

Any help would be appreciated...

thanks

The SOLO os stuff is also available on bitsavers

http://www.bitsavers.org/bits/DEC/pdp11/Brinch_Hansen_SOLO/

most of the Brinch Hansen's stuff is not online, but googling
might turn up documents.

My UCSD pascal image for pdp 11 can be downloaded from here:

  http://rly2.dyndns.org/UCSD-bootable-rk05.zip

This is a snapshot of the disks that I used to build a bootable
pdp11 version of UCSD II.0. There is a README.TXT file that
has more information. The main image that you want is rk0.dsk
(rtv4_rk.dsk is an RT11 disk that I used to assemble the pdp
boot blocks).

When I was doing my masters, I worked on OCR/IR... It has been a while but some 
things to consider:

Accuracy can be improved by proper training with known ground truth data. If 
the typeface of the RT11 manuals is the 'DEC' standard and matches the other 
scanned files. You can use that for training: produce images from the DOCUMENT 
output along side straight ascii... There's the initial ground truth.

Tesseract  is the OCR engine, there is a project called octopus that provides 
layout and other processing using tesseracts for OCR.

You can improve accuracy by using multiple OCR engines and vote on the results.

Some packages that may help: tesseracts, cuneiform (another OCR engine from 
Russia). Unpaper is a package that can help clean up scan images before ocring.

Having said all of that: for my personal stuff I use gscan2pdf under Ubuntu 
since it includes most of the above packages in a GUI.

[Simh] Datacraft 6024/3 (was Re: Looking for a working 9-track magtape transcription setup)

2015-12-02 Thread Ron Young

Hi:

While I can't help with the tape drive issue, I can provide
some background about the machine...

The datacraft 6024 is the same architecture family as the Harris
Hxxx machines (IIRC the 6024/3 was rebadged as H300 series).

In addition to academic sites, the u.s. army corp of engineers had
alot of these machines.

So if software for the Hxxx series of Harris machines is found it
would be useful for this class of machine as well.

I was a systems programmer on Harris H800 at UNLV for several years
in the early 80's so I may be able to help with software/OS questions.

On the Harris, the os was called vulcan (and later VOS) that may
help on search terms.

[Simh] [SOLVED] what is the recommended way to config network for simh/VAX

2011-09-08 Thread Ron Young

Hi All:

   I have resolved my problem with simh networking...there was an old
   version of libpcap installed from the ubuntu repository on the system...

   Removing the repository version and following the 0readme_ethernet.txt
   and Phillip's instructions everything work like a charm.

   thanks again

[Simh] what is the recommended way to config network for simh/VAX

2011-09-07 Thread Ron Young

Hi All:

   I recently upgraded my ubuntu box to version 10.10 and I'm trying to
   get openvms/vax (hobbyist 7.2 CD) to use networking with simh
   3.8.2-rc2. Since I haven't played with vms for many years, I'm using
   Phillip Wherry's web page as an installation guide 
   (http://www.wherry.com/gadgets/retrocomputing/vax-simh.html)

   I'm confused on what is the correct method to configure the
   network. I've tried several different approaches with no success
   (and some like bridging with taptap as described at 
   http://www.retrocomputinggeek.com/retrowiki/SIMHNetworking/ ended
   up "hanging" the interface -- no fun when working remotely).

   Does anyone have a straight-forward procedure (config files, specific
   packages, etc) that is known to work?

   my setup is:

  ubuntu 10.10 (32bit) Linux 2.6.32-33-generic-pae
  simh-3.8.2-rc2 (from the downloaded zip file simhv38-2-rc2.zip)
  wired ethernet interface (eth1 ip: 192.168.2.xx/24).

  Downloading the taptap.c version referenced on the 
  retrocomputinggeek.com webpage results in an empty file/blank page
  in browser).
  
  I tried two different versions of taptap: taptap-1.0.tar.bz2 
  (http://www.munted.org.uk/programming/taptap/) and taptap-modified.c 
  (http://www.itsecuritygeek.com/files/taptap-modified.c)

   Any help would be greatly appreciated,

   thanks
