Mr glitch, I have recently restored a PDP11/23 in the form of an SMS DSX11 with the ability to read and write RX01 and RX02 disks. SMS has their own controller to do both these formats along with IBM1, IBM2. This system also has an operational KERMIT11 so I can transfer things at the file level to my Windows machine. This option is easier in a lot of cases than battling disk images. So I offer this service to you if you want to preserve some old data. I have an operating imagedisk system with 8,5.25,3.5 drives too.

Oh, no worries, I have all that as well, and I'm not about to ship them halfway across the continent vs. just getting my machine up and running :p I would also prefer actual diskette images and not just files, since there may be Important Stuff on the system tracks, in deleted-but-still-there data, etc. Thanks for the offer, though!

(we're talking 500-1000 diskettes)

I'm kind of in the same boat. I have about 20 linear feet of DEC 8" disks, some RX01 and some RX02. I'd like to image all of them including some interesting ones that came with my H11. But UPS nicely smashed in the doors of both H27 drives, and an errant 50 year old label jammed the fan in my RX02 and let out the magic smoke. Some of the more interesting disks that came with the H11 look like they might contain some kind of helicopter flight simulator from Ft. Rucker (now Ft. Novosel).

Anyway, I'm ever so slowly inching my way towards being able to read/image 3 and a half 4 foot shelves of 8" disks and involving a greaseweasel in the process is my current plan. So if you happen to go that route, please let us all know about any bumps in the road you encounter.

Hi all, I work with a v4 version to Image my vintage floppies quite successfully. So many thanks and greetings to the project team :-) ! I have also a bigger amount of DEC stuff laying around where...

The soon-to-be-available-again Applesauce imager makes quick work of RX02 M2FM diskettes. Also handles Intel Intellec M2FM. The AS was based on a microcontroller that became complete unobtanium at the start of the pandemic and the unit was recently redesigned to work with a different controller. In Beta test currently.

Any chance the Applesause will be able to image the intel intellec SSDD m2mfm 8" format? That one's a booger too

Yes, without any problems. That's what I was referring to above. I've always called it M2FM, but that may be inaccurate terminology. I've read both DD ISIS and RX02 diskettes.

Purchased one of these online. The installation and support manual is available but no software. Does anyone have experience with one of these?
The software package included CP/M and utilities.

This is not a feat, this is my program ImageUtils :)
Code: 
ImageUtilX -unpack DECMATION_100Q_DISK2.rx02_sd @DECMATION_100Q_DISK2.rx02_sd rx01 rt11

For the other two disks - (at least) not yet - the program does not know how to work with CP/M FS.

Hunta, please help me here.
I need to recreate all 3 of these disks.
I bought the DECMATION 100Q board today but there will be no disks.
I have a working imagedisk system with 8" drives.
And I have a working PDP11/23 with KERMIT.
So the individual files you made from disk 2 will work for me.
How about the other 2 disks, they CPM file structure right?
If they are 8" SSSD 128 byte sectors then can you make a .imd file for me so I can build the diskette?
I will need all sectors on those because there are boot sectors outside the file structure.
One of those disks should have SEN.COM and REC.COM cpm programs.

My program currently does not work with .imd images - it neither reads nor writes such a format. And for FS СP/M it was done (only for one of the variants of this forma) only files extraction.

This can probably be done with a raw image and vtserver.

I have an 8" drive, but it is not known whether it works or not, and I have not tried to connect it anywhere. So everything will be done under the (russian) PDP-11 emulator, fortunately it also emulates RX-01/02. I can transferr files between a PC and a "hardware" PDP-11 this is not a problem for me for a long time, thanks to the (russian) VT-52 emulator with a built-in transparent disk emulator - approximately like in tu58fs, only a non-standard hard drive is emulated.

I don't need the floppy disks, I can make them if I can get a .imd file 8" SSSD 128 byte sectors.
I'm pretty sure that's what all 3 disks are, with one being RT11 file structure and two being CPM file structures.
Can you make me 3 .imd files?

Since the disk structure is known, you can generate IMD files from raw images and write those out -- ImageDisk includes a tool for it. It also includes one to go the other way, IMD to raw binary images. It runs under DOS, but will of course run fine in DOSbox or some other emulation for just running the utilities.

From your previous postings I've collected all the files within the file structures to create the 3 diskettes, but not any boot tracks for the 2 CPM diskettes.

I'll await my D100Q shipment and maybe I'll be surprised that the diskettes are included, and if they are I will IMD them.
Should know this week.

Thanks for your help.
 
If not let me know and I'll IMD the ones I got with mine. It looks like it's probably just a distribution copy.

IMD files created from the original disks along with all their boot sector information would be a good addition to bitsavers. Can that happen?
I'm moderately concerned about attempting to recreate IMD files in various other ways.
Again, I have gotten all the individual files from the RT11 and CPM file structures, just not the boot sectors outside the structure, which D100Q might need.
