yes :) we are good in electronics & restoration of those
computers :D

well - problem is now that disk doesn't spin. Something happened
in those years - I remember we used this RL02 unit some time ago

We have about 40 disks, with RT-11 on them (and an add on
operating system for RT-11 called TSX), plus some diagnostics &
other stuff. This PDP-11/34 was used for a medical CAT
equipment, it's called "GAMMA-11" so it has special boards and
special software on it for image processing... (we don't have a
monitor for it)

We made backup connecting this RL02 unit (that now is not
working) into a MicroVAX-II, making it boot thru a DECNET
connection into a SimH emulated vax; from this, we can make
backup of the disks and have files on the simh pc; they are
available for our online emulator at "telnet poetry.voyanet.org
1134" (now only one disk pack boot, I need time to create a menu
to choose which disk pack to boot :D )
