Just in these days we restored a PDP-11/23PLUS here at our
Museum! :)
we had to create the power supply with a normal PC PSU and also
we made the 50Hz signal clock using a PIC. CPU is working and
we're trying to boot from a RL02 unit :)
we're experiencing problems at our website so we have pictures
and info only on our facebook group, sorry for that.

the disruptive
fact (in terms of time) here is to put up-to-date both
the PDP-11/23-PLUS and RL02.
My apologies, I just now noticed that you have an 11/23-PLUS (it is slightly
different from a plain 11/23).
I am not very familiar with the 11/23-PLUS (I never worked with one), but from
documentation I just dug out, it seems that they normally come with the MMU
chip, so we don't need to worry about that. However, the FPP is not standard,
so that is still an issue for bringing up Unix.
