Hi,
I am just getting a PDP11/23plus. The CPU is already at home and I
have powered the machine up. Makes noise, turns fans, etc. If I
start the machine (running indicator lit) it gives me a dollar sign
('$') prompt
which seems to accept two character until it starts a new line.
Here a few (perhaps totally stupid - but I've never used such a toy
before) questions:
What's that?
What can I do from there?
Is it normal?
Sounds like the bootstrap of a device controller, not the KDF boot
ROMs. You can probably type type characters for controller name and
another for device number, e.g., DU0.
You need to carefully inventory your boards and determine what you have.
Then look around (bitsavers, e.g.) for appropriate documentation.
