Just had a look at an image patched to 469. There are
awesome
improvements. There is top, swap space and a clean flag. I will try to
get it to 473. The clean flag is really useful, because the complete
fsck of the RA92 image on the ESP32 take at least an hour. On the
first glance it looks like someone investet a lot of work into
a proper startup.
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.
