Imaging RX02 disks for simh (was: Re: MU-BASIC V2 and RT-11 V03B distribution disks.)

How the heck do you copy an RX02 disk for use in simh? I've been trying to transfer RX02 images between simh and a real PDP11 (that has only two RX02's, console, and ethernet). So far, I've only attempted sending an RX02 image from the PDP to simh, but simh fails to read it: "?DIR-F-Invalid directory". Even after adding 13*512 bytes to the start for the missing track, I still get invalid directory. My process is to COPY/DEVICE/FILES DY1:/START:0/END:330 DY0:BLOCK1.DAT, then FTP that off the PDP, delete the file, and do the remaining two thirds of the disk. Once all are transferred, "cat *DAT > floppy.dsk". I can transfer RX50 images using the same recipe, though I haven't tried sending an RX50 image created on simh back to the PDP. For what it's worth, I'm having the same problem with Alan Baldwin's TCP/IP disk images from http://shop-pdp.net/rthtml/tcpip.htm. simh can't read the individual DSK images, but could read the *.PKG with the disks inside, and from that, I could (RT-11) MOUNT each disk to a logical device. b >I found some 8 inch floppies with distribution kits for MU-BASIC V2 and >RT-11 V03B.
