Short after I have started collecting DEC PDP and VAX Computers, I have realized, that it is a problem to get installation media. At the PC side, it is quite simple. Put a 5.25″ drive or a 3.5″ one into a PC with DOS or Windows 9x and you are ready to write the images onto your Floppy Disk. All needed stuff is available, in each version and language, OK, mostly also on the DEC side, but hold on, the Media and drives you need, are not common and not easy to operate.
So my first plan was to use an 8″ Floppy to write images, were you need the following things:
-8" Drive with Shugart interface -Power Supply which provides the needed 24Volts -50 Pin to 36 Pin adapter with some small logic on -at least a Software witch can write the images
I have by now not spend 120 US$ to get the dBit set via http://www.dbit.com/fdadap.html, but it is still on my wish list.
Due to some luck and the kindness of Andreas, who gave me a RT11 Floppy Disk Set, with my last Haul I’m now able to install all my PDP’s via RX02, which is fine for me.
First step was to image the disks, as I would not like to use the original ones for this daily work. I have done this with the PDP11GUI from Jörg Hoppe, which can be found here: http://retrocmp.com/tools/pdp11gui
It is a great tool, which has allowed me to image the RX02 Distribution Media, and to write it back to a working copy. And the best, you don’t need to connect any 8″ Drive to a PC, a running PDP with connected RX01/02 is sufficient.
But stop, I missed a important part!
RX01 and RX02 Drives can’t low level format their floppy disks, means you need IBM 3740 formatted disks. Unfortunately all of my 8″ Disks where unformatted, which was a disaster, as I was not able to use them. I have decided to ask DEC enthusiasts via cctalk Mailinglist, if someone is willing to sell a bunch of them to me. As my understanding was, that it is not possible to create RX02 media due to the strange mixed FM/MFM format they consists of. When you ask persons with a big knowledge about such stuff, you will in some cases get important information. The outcome was, that you only need IBM 3740 formatted disks, which can than be formatted under RT11 to RX02 media.
Bingo! At this point I was thinking about my IBM System /23 (Datamaster Type 5324). I had played around with them some months ago, and reminded me, that the system can use and format three different Formats.
Load the formatter from VOL001 or VOL002 Floppy Disk via: link prepare and follow the screens.
1. IBM System /23 Format 512 Bytes per Sector Possible Disk: SSSD, SSDD, DSDD 2. Standard Format 128 Bytes per Sector Possible Disk: SSSD, SSDD 3. H- Format 258 Bytes per Sector Possible Disk: DSDD
After I have formatted all my disks via Option2 it was no longer an issue to format them under RT11.
.FORMAT DY1: DY1:/FORMAT-Are you sure?Y ?FORMAT-I-Formatting complete . .INIT/BAD DY1: DY1:/Initialize; Are you sure? Y ?DUP-I-No bad blocks detected DY1:
After this was done it was also possible to use PDP11GUI to write my RT11 image back to the new Floppy Disks, to have a working set for installation. This is not possible with unformatted disks, as the write process is not like a low level block by block read/write.
And that’s how it looks when you install RT-11 5.4G via RX02 Media onto a DEC PDP-11/84.
Installation protocol of RT-11FB V05.04 G on my PDP-11/84 SCSI Disk.
The RT-11 Distribution Set consists of eight 8″ Floppy disks You should create w working set, and keep the original set at a save place.
The SCSI Disk is attached to a Dilog SU-726A Unibus Controller, which presents the disk as MSCP device „du0“ to the PDP/OS.
By the way, when you see a message like: This distribution set is not for this system….. than verify if your MSCP Controller is on default CSR 172150.
Simply boot from the Disk Named …Auto… he contains the installer.
By the way, after this Installation you are able to create boot tapes.

Welcome to RT-11 V5.4G You have bootstrapped the RT-11 V5.4G Installation Diskette. Your RT-11 V5.4G software package has two sets of RX02 diskettes containing identical copies of the RT-11 software. Each set consists of a 7 diskette operating system and one installation diskette. One set is your master copy; store it in a safe place. The other set, from which the installation diskette is now mounted, is the set you will use to build your working system volume. Press the "RETURN" key when ready to continue. You will be guided through the installation process by a series of instructions and questions; you will have an interactive dialog with the RT-11 installation program. All you need to do is follow the instructions carefully. If the instructions ask you to mount a diskette in a specified drive, find the diskette with the correct label and mount it in the drive, as shown in your installation booklet. Remember that the RX02 drives are numbered from top to bottom on a horizontally mounted unit, and left to right on a vertically mounted unit. The top or left-hand drive is DY0 and the bottom or right-hand drive is drive DY1. Press the "RETURN" key when ready to continue. Your working system will be built on DU0... Press the "RETURN" key when ready to continue. Please enter today's date in the following format: DD-MMM-YY where DD is the day of the month MMM is the first 3 letters in the name of the month YY is the last two numbers of the year For example: January 1, 1987 is 1-JAN-87 Type in the date, then press the "RETURN" key. 8-AUG-97 Please be sure the DU0 device is on line... Press the "RETURN" key when ready to continue. The disk in DU0 is now being initialized. The following procedure should produce informational messages in the form ?FORMAT-I-Message, or ?DUP-I-Message. No action is required as a result of these messages. If BAD blocks are detected, the block number will be provided. This information should be noted for future reference. This can take approximately fifteen minutes.

RT-11FB V05.04 G .TYPE V5USER.TXT RT-11 V5.4G Installation of RT-11 Version 5.4G is complete and you are now running RT-11 from your system volume. Your system volume is your working volume if you have used the automatic installation (AI) procedure. If you have installed RT-11 using that procedure, DIGITAL recommends you verify the correct operation of your system's software using the VERIFY verification procedure. You can only perform VERIFY on the valid target (output) media you used for the AI procedure. Run VERIFY before you run CONFIG. To run VERIFY, enter the command: IND VERIFY DIGITAL also recommends you read the file V5NOTE.TXT, which contains information formalized too late to be included in the Release Notes. You can TYPE or PRINT V5NOTE.TXT. Also see Section 3.1 of the RT-11 System User's Guide for information on tailoring a start-up procedure using a start-up command file. .R MSCPCK .dir 08-Aug-97 SWAP .SYS 27P 19-Dec-88 RT11FB.SYS 93P
