I have at least one working ESDI hard drive so that will be my boot
device. My real problem is removable media. Even though I have an
RQDX3 to control an RX50 drive, I don't have a working RX50 drive.
Same goes for the TK50. I have non-working versions of both drives
but nothing I can use to move software onto my system. Anyone have a
working RX50 and/or TK50 drive they can spare?

See my other post about the dual RX33. You use a PC
5 1/4" HD floppy. Under RT-11, the RX33 can even
do a LLF (Low Level Format) on the RX33. I nearly
fainted the day I tried it for the first time using
a real PDP-11/73 with an RQDX3 and RX33 drive AND
running RT-11.
In order to move software to the real PDP-11, the RX33
with 2400 blocks is about half the size of an RK05 drive.
This is probably satisfactory for anything with RT-11.
What use do you expect for your PDP-11? If you are
running RT-11, ask as much as you like, but remember
that I download only about once a week, so you will
probably have to wait most of the time.
Sincerely yours,
Jerome Fine
