Lessee...I know more about life on Mars than I do RT11, but I know
from trying it myself, while building some XXDP volumes, that a simple
DIR command can't read an XXDP volume. Maybe there's an equivalent of
FLX (RSX) or Exchange (VMS) on RT11? Either way, you can test your
ability to read an XXDP TU58 on the PDT by doing a DUMP/TERMINAL DD0: -
if it reads, it will dump the blocks out to your screen. It will be
interesting to see if a real TU58 works as well on a PDT as an emulator
does.

Very nice to know! I am repairing my tu58 bit by bit and will try it
out on my 11/150. Good to know about the serial limit, I'll jumper for
2400 baud to test.
Question. The only tape I have for testing is an xxdp. Are they in
rt11 format that I can test with a simple directory command?

I've been tinkering with a PDT-11/150 lately. It's a little
inconvenient to work on, since it doesn't have a simple way to
transfer files back and forth (KRTMIN doesn't work when
transferring files to the box, just from the box, for some
reason I haven't been able to puzzle out, and pasting text
into a KED screen or a PIP command usually overflows my
terminal emulator). It occurred to me that the first
application terminal line on the 150 is at 176500,300, the
same as the default for a TU58's DL11. It's a very DL11 like
interface, register wise. I'm wondering, if I could hook up a
TU58 emulator and use it to move data back and forth to the
150. Has anyone had occasion to try this? Any advice on how
to get it to go would be appreciated, since I know very
little about RT11.

OK, replying to my own post here, on the off chance that there are any other
PDT-11 hobbyists out there. I gave this a try and it works pretty well. The DD driver on
the PDT-11/150 will talk to a TU58 emulator on Terminal 1 just fine (presumably, it would
talk to a real TU58 as well). It only works at 2400 baud, but, it's still pretty useful
for moving software on and off the box. With the "big" TU58 patch to the DD
driver, it's also possible to store lots of RT11 software or data (65000 or so blocks
worth) on a virtual TU58 and load from there, rather than switching floppies.
Seehttps://rsx11.blogspot.com/2022/05/pdt-11150-and-tu58.html for the long boring story
about figuring this out.
