Hi,
thank you all for the tips around my harddrive desaster. Next time I
will be wiser.
I have cleaned my removable disk's heads. Used isopropanol and a match.
Tried the crashed disk pack, crashed again immediately. Had to clean one
head again. Took another pack. No crash, no error display etc. Hope that
it stays ok.
It sounds like you have been _very_ lucky...
Now I did:
I haev an idea it _does_ come from the disk boot block :-)
$dm4
.. And dm0,1,2,3 work same way....
Computer says:
**THIS VOLUME DOES NOT CONTAIN A HARDWARE BOOTABLE SYSTEM ***
000034

I would be glad if that is a message read from the disk partitions (like
the bootsector message on non-system disks in my pc). What is the "modern way" to get software
into the PDP11?
Is there anything like a RIM or BIN loader?
It depends on what you already have on the machine. If you have an OS
that supports the TU58 tape drive (don't worry that you don't have such a
drive), you can emulate the TU58 on a PC (or unix box). It's a
block-structured device that works like a (very slow) disk.
There's also something called VTserver that I believe is a way to
bootstrap software onto a PDP11. I've never used it, though.
