Well, would you believe it. It was the disks after all. I can't believe
they are all bad!
Just booted straight into RT-11.
Thanks all for your help anyway. Time to play.

Well, I'm glad you got it working. Where'd you get a good floppy?

Friend popped over with an RX02 drive and a working RT-11 floppy. The
drive worked with my controller so I tried the disk in my own drive and

I can believe it.
Were they "bad"?
Or just not what they were labelled as being?

We've gotten around the formatting issue by formatting SSSD using ImageDisk
on a regular PC (with a floppy controller that supports single density/FM,
of course). If you want RX02 media there's an XXDP routine to upconvert
RX01s to RX02s.
Thanks,

I just checked all of them in RT-11, out of 12 floppies, two of them
were bad, or at least I am unable to perform dir in RT-11.
My source of confusion comes from both A) not being able to boot from
any of them, and B) not being able to dump them using vtserver. The ones
labelled RT-11 don't actual
Glad to hear that you cleared that up.
For the other floppies.
1) DUMP/TERM/RAD50/END:0 DY1:
If you share the listing that will give us some hints as to the OS on the
floppies.
2) DIR/BAD DY1:
will do a bad block scan to see if can read all of the blocks on the media.

Why don't you reach out to the person and tell them you _r
If you have a system that can create/format SSSD (base RX01 media
format) RT11 can
reformat that as RX02. Of the top of my hear the command is INIT and
you specify the
drive and /double. It cannot format a blank disk but it can set a RX01
format to
double density.
Note a RX02 on a PDP-11 will no
Thanks for the tips! :)

16c550s are cheap as dirt. And you can stick a 16c850 or whatever the
latest incarnation is to a PLCC to DIP adapter.

Chuck really has the right answer here. UAR

Yep.
Being labelled "RT-11" does not mean that they have RT-11 on them.
They could be Compupro disks from the

Ha. I lost a bit of hair when I received a batch of 8" hard-sector
disks and tried to make sense of them. What were obviously sector
headers didn't line up at all with any of the sector hole
