Anyway, I
hooked a terminal up to it and lo-and-behold, a prompt. Now, I've
never owned a PDP-11, so be gentile, here. How do I get it to run a command
shell? I have installed two RK05 drives, the 0: drive has a {supposedly
good} RT-11. Upon boot, I get the following on the terminal:
000000 170002 170002 165360
$
I'm assuming that the "$" prompt is the monitor prompt. It seems to
only
accept two-letter commands before performing an auto-carriage-return. The
"165360" is also on the front panel display.
OK... Assuming all your hardware is working and at the standard addresses
(it will be, unless somebody has messed about with it), try the following.
1) Turn on the machine, drives, terminal
2) Put a good boot pack in drive 0. Flip the load/run switch on the drive
to run. The disk should start spinning, and after a minute or so the
heads should load. The READY and ONCYL lamps should light. Keep a finger on
the load/run switch and an ear to the drive. If you get unpleasant noises
when the heads load, suggesting a partial headcrash (the sound has been
described as a cat being fed backwards through a lawnmower!), then flip to
LOAD at once and your heads may still be useable.
3) Type DK <CR> (or DK0 <CR>). It MUST be in upper case. The RD and WR
lamps on the drive should flash a bit, and the machine will boot. If it
doesn't do anything, then either you don't have the RK05 boot ROM in
the system, or you have some hardware problem.
