The header line says it all: another panel for BlinkenBone is there,
the classic PDP-11/20.
In function and style it fills the gap between the PDP-8 and the
later PDP-11's.
The GitHub distribution starts the 1970 Paper-tape BASIC, download
here: https://github.com/j-hoppe/BlinkenBone/releases

Thank you! That was the first PDP-11 I ever used (and programmed in
MACRO-11).
I ran DOS/BATCH and also RT-11. And I also ran a UNIX system on it.
Do you remember which UNIX?
I always considered the 11/20 to be too weak for that (no MMU, despite
18 ADDRESS switches&lamps). Or am I wrong?
Thanks for feedback,
Joerg
