So I took the 2.11BSD pl469 (is there a custom how to specify the pl?)
from PiDP11. It is a bit larger than an RA72. I truncated it to the RA72
size, because simh would only use it r/o. I haven't noticed a problem
because of this and the partitions look good, although I would have
partitioned it differently. 8MB for /, 410MB for /usr and 550MB for
/home. / is already 44% full.

Patching went well. Pasted a shar of a tar, because I am still not able
to read a tape. (Tips on simh configuration and device?) Haven't looked
at pl469, but I can say pl473 is really nice. It boots after a few seconds
on its own just like a modern Linux. It is doing also a fsck just like a
modern Linux depending on the state of the fs. Initializing everything
down to the multiuser state and login. AFAIK 2BSD was used in the past
for doing work. I would have expected something like it is now from old
2.11BSD versions. Maybe the automatic booting with timeout is a newer
invention and top a newer software, but the features, which were there
should have been working in a conventient way. In case someone here
helped making the patches: Thanks!

With my port of esppdp (based on simh 4) to the M5Stack Core2 and the
wifid daemon from esppdp I have now a nice running PDP-11 in a box of
5.5*5.5*1.5cm. Screenshot of top running on it via a telnet login.
