I had the idea that I'd like to boot RT11 on an machine with a RX02 drive. But what is the way to write arbitrary image to a RX02 diskette?
I can create bootable disks on SimH but how to transfer the disk image onto a floppy?
The RX02 is special so it cannot be written or read by a standard PC floppy controller. I have a catweasel card which at least read a RX02 diskette without (not that much) problem. But how to convert back and forth the raw disk image from the DMK format? I have tried an old lib developed by Eric Smith called dmklib but seems not to support RX02. Hints are welcome here!
Or is the only way to boot RT11 from some hard disk and then create bootable disks? I really like to do the fiddling in SimH and then just transfer the image onto the media, but that might not be possible?
I did have some problems reading a number of RX02 formatted disks. From track 44 an onwards it started to fail on reading. Does this has to do with the media, the drive that was used for writing or the drive used for reading? The drive read other disks past track 44 without any problems. I am using a Shugart 851 which seems to have some jumpers that would be able to control the reading filters some how. Haven't tested yet though.
