Jerome Fine replies:

I seem to remember that was the first Unibus PDP-11 I
used in 1975. Does yours system still work? Do you
have disk drives or paper tape? Do you use an operating
system? RT-11? Would you like a copy of RT-11 that
will work with your hardware? It will be a bit difficult
with so little memory, but probably possible. But it does
require at least a floppy disk drive or an RK05/RL01/RL02
or even a TU-58 if you have an RS-232 serial port (you could
toggle in the TU-58 boot program instead of the one for the
RK05). That was the one thing about the PDP-11/05 that
was really handy - the boot program in core memory could
be easily changed and did not disappear when the power was
turned off. Of course, I can't ever remember doing that in
the 3 years that I used the PDP-11/05 since the RK05 drives
were the only ones it ever had.

Sincerely yours,

Jerome Fine
