Tandy Assembly is Oct 2-4. Anyone planning to attend this year? I am going
to get a hall pass from the old battleaxe. The airline prices are really
good right now, for me at least.
I am going to be a sponsor.

Hello all,
I am at a bit of a loss. Looking to repair a dos computer that runs a big
cnc machine. I need to load some kind of packet driver, so that the pc tcp
software from the company "ftp software" can be loaded. Another supporting
machine passes data to this machine to drive the machine.
Attached are some screenshots. Original card was a pci etherexpress 100.
The packet driver used is in the screenshots attached.
I no longer have a intel card, is there a way to just drop in any old pci
card and make it work with the tcp ip software?
I am trying to better understand, as i have not done much work with packet
drivers. I will post back with some more info. Any help much appriciated.

I have been able to bring up the DECnet-RT images, that Jay posted a few weeks ago, on OpenSIMH. Below are my notes on how to get it running.

Notes for getting DECnet-RT V2.1 running on OpenSIMH
NOTE: DECnet-RT is a phase III system so it does not understand Phase IV areas
and can only address nodes in the range 1 - 255. If you attach it so a
Phase IV router (e.g. PyDECnet) it can be accessed as node nnn in the
area that the router is in. If you are bringing it up as part of a
larger network (e.g. HECnet) make sure you "own" it's address otherwise
you may cause routing problems.
I have tried running DECnet on most versions of RT-11 from 5.0 to 5.7. Any
version after 5.4D has various problems with file/terminal I/O.
The available images will only run on an unmapped system with
background/foreground support. This means that everything; monitor, disk
driver, DECnet and application must fit in 28KW. Later versions of RT-11
slighly increased the size of the monitor and/or disk drtiver so that NFT and
FAL will not fit in memory. DECnet-RT requires features that are not provided
in the distributed monitors so you will have to generate a new monitor (See
RT-11 System Generation Guide). You can take all of the default answers except:
"Do you want the single job monitor?" Answer N
"Do you want device time-out support?" Answer Y
"How many extra device slots do you want?" Answer 4
Once you are running the new monitor, copy all the files from the 3 RX50
floppy images (RX0808.IMG, RX0809.IMG and RX0810.IMG) to your system device:
COPY/SYS DUx:*.* SY:
The system is configured to use a DLV-11 (CSR 176500, vector 300, priority 5)
for network access. Add the following lines to your OpenSIMH .ini file:
SET CPU 11/23
SET DLI ENA LINES=1
SET DLO0 DATASET 8B
ATTACH DLI LINE=0,SPEED=115200,CONNECT=<IP ADDR>:<PORT>;NOTELNET
If you are attaching to PyDECDnet, the associated configuration line would be:
circuit dl-0 DDCMP --mode tcp --local-port <PORT>
where <IP ADDR> and <PORT> need to be set according to your network.
The network configuration is in a file called "CETAB.MAC". We can use CFE
(Configuration File Editor) to change the node name and address (in this case
to node name RT11 at address 111):
.R CFE
File name <SY:CETAB.MAC>:
CFE>LIST EXEC
Executor permanent characteristics as of 00:00
Identification = ERC PDP-11/23
Name = ERC23, Address = 124
Host = 124, Maximum links = 4
CFE>DEFINE EXECUTOR NAME RT11 ADDRESS 111 HOST 111 IDENT "RT11 11/23"
CFE>LIST EXEC
Executor permanent characteristics as of 00:01
Identification = RT11 11/23
Name = RT11, Address = 111
Host = 111, Maximum links = 4
CFE>DEFINE NODE 112 NAME REMOTE
CFE>EXIT
The last DEFINE command defines nodes in your DECnet network so you can connect
to them.
To load DECnet:
.ASSIGN SY NT
.R NCP
NCP>SET SYSTEM
NCP>SET EXECUTOR STATE ON
NCP>SHO EXEC
Node volatile summary as of 00:00
Executor node = 111 (RT11)
State = On, Identification = RT11 11/23
NCP>EXIT
If you want to allow incoming connections run NJS (Network Job Spawner):
.R NJS
?NJS-I-Network Job Spawner Active
and then it will report each program activation.
The following programs are available:
NCP - Network Control Program
NFT - Network File Transfer
TLK - Interactive talk with another (remote) terminal
RMT - Remote terminal (RSX)
RVT - Remote terminal (VMS)
CED - Dumps internal DECnet data structures (/AL dumps everything)
The following servers are available:
NML - Network Management Listener (use with NCP)
FAL - File Access Listener (use with NFT)
LOOPER - Loop testing (use with NCP LOOP NODE name)
