OK, I've got the RX02 virtual disk images I want on my 486 (it's the one
with the 1.2Mb floppy, booted into DOS, and started up 'putr'. I made a
RX50 using putr, and go to copy the smltcp.dsk image to the RX50.
Unfortunatly it complains that there isn't enough room. I take it that a
RX50 is less than 500k? I think the image is 492k.
Is there some way that I can split the disk images and then recombine them
once I've got them copied over to the /73? I'm just not feeling energetic
enough to want to move a RL02 drive around and juggle the controller
between my MicroVAX and /73 to get the files transferred tonite.

Which version are you running? LD: wasn't a standard distributed
driver until V5. For pre-V5 systems, there are DECUS equivalent
drivers.

The ///+'s are definitely marked as that. Unless the "+" got rubbed or

Thanks, Tim... I took him at his word that he had RX02 images...

Time for a mobile crane or at least a heavy-duty cherry-picker? :-)

There is an RX02 emulation in Bob's package (that I remember). The only
thing I can think of which might affect whether they are readable is
whether the disk images you have are sector-by-sector image copies, or
block-by-block image copies. If they were copied using one technique,
but read using the other, then you'll actually be mixing unrelated
sectors together to form a block.
I would have to check the source (or ask Bob) which technique is supposed
to be used to make image RX01/02 copies so that they work.

Umm... 8" is what pretty much defines RX02s... I don't know of an RX02
which was other than 8" (except for the advanced development RX's which
communicated with the controller via FDDI back in 1983 or so which I
got working using a modified DY handler).

Well actually I have a SUN branded version of TOPS for the MAC and a Centram
branded version for both the PC and the MAC. I guess it's going from hand to
hands or maby on is a clone of the other.I haven't installed them yet but
I'm planning on using them to hook my MACs to my PC network with a FlashCard
on a dedicated PC..

You put the disk image on a RT-11 disk and mount it using the LD:
(logical disk) handler. Logical disks are RT-11's implementation of
subdirectories, and you can even have logical disks inside logical
disks. As an example:
