Hello, made some progress with the pdp 11/34 I picked up a while back.
Managed to repair the faulty power supply. I am in the process of trying to
get a minimal configuration of the machine up and running.
I am looking for a short program to key in to try and test the
functionality of the cpu. Is there anywhere aside from the DEC manuals I
could go to get a quick idea of how to operate the front panel? The manual
is very in depth, however i am looking for sort of a quick start guide to
get started pretty quickly. Any site with info on how to operate the front
panel or some quick short programs i can key in would be of interest.
I almost have the whole machine put back together on my desk, if all goes
well and it runs as expected, i want to post back with some nice orderly
pictures of it in the rack next to all the drives and the tape Drive.
Progress overall with the whole machine has been slow going, the machine
came with a heap of rsx 11 disk packs and tapes, however I am not to the
point where i can use them just yet. Ive been kinda itching to see whats on
those tapes, hopefully soon.

The front
panel is very simple. Most of what you need is:
1. Load address (LAD button) sets the memory address for
further operations
2. DEP deposits data in that address, and increments the
address
3. EXAM examines data at that address, and increments the
address
4. START starts execution at the previously loaded address
That's pretty much all you need to know.
I did use simh to show my kids what's under the hood, we
wrote a little sort program, but I don't think it was ever
in a file. We just typed it in live.

Hi Devin,
if you have the M9312 boot strap card: do you see the console emulator
prompt?
If the machine HALTs on power-up, some micro coded diagnostic failed
=> bad!
If you see the M9312 prompt, you can use PDP11GUI for further testing
Then you can write own assembler programs and download paper-tape based
diagnostics. Contact me for more.

Thanks, I look forward to trying that out tonight. Thanks for the quick info on how to
operate the front panel. As far as the boot card goes, I do have one, but I do not have
the vt100 connected at the moment. I. Will get it all set up and post back tonight, using
pdp11gui to load the dec diagnostics sounds like the way to go.
