Hi Jerry,
I have tried with PDP11GUI, but the first message says "The image
contains only 505856 bytes, but disk has 512512 bytes".
I have written some disks, and have ignored this message, but none of
them is readable under RT-11.
.dir dy0:
?DIR-F-Error reading directory
So I think the DSK format is different from the one PDP11GUI uses.
In the documentation I have seen, that the format is the same as SimH uses.
>>
*Image file format*
Every DEC disk or tape is logically represented as a linear list of
“blocks”. The block size differs between 128 byte and 1024 bytes.
Reading and writing is based on block numbers.
The file format is that of SimH: a file image is just a stream of blocks.

Kermit would be a possibility, and I will try it later on.
Many Greetings
Ulrich

Hi all,
maybe someone can help.
I would like to install TCP/IP on my RT-11 system.
After a short search I have found the following, which I would use:
http://www.classiccmp.org/PDP-11/RT-11/freeware/decus11/110939/rthtml/tcpget.htm
But the images are in DSK format, but I can't write them with PDP11GUI, which
is the only way I have at the moment.
I like the PDP11GUI implementation and way, as there is nothing more you need
as a PDP and a RX02, which is in most cases available.
Someone here, who has the equipment, time and mind to write the DSK files onto
RX02 followed by an new image via PDP11GUI?
Or is there any other suitable way for me?
Hi Ulrich,
I haven’t used PDP11GUI, but you should be able to use it write the DSK files
from PC to an RX02. Did you
encounter some problem? Alan has provided images which are RX02 sized. This
site has the latest distribution
http://shop-pdp.net/rthtml/tcpip.php
Otherwise - check this site for a copy of kermit -

Note especially, the bootstrap process for RT-11. You basically copy the files
as text down to the machine.
Then you compile a macro program to convert the .HEX file to a program. That
minimal
kermit will then allow you load other data and programs, including the full
featured Kermit-11.
I’ve used this process myself using any basic terminal emulator.
Paste the text via either an editor or using COPY TT: to DK:FILE.TXT
(terminate with a CONTROL-Z).
