I feel amazed that you wrote a PDP-11 assembler. How did you verify your code? Did you have a real PDP-11 machine or you tested it on an emulator?

P.S. I know someone who still has a PDP-11 in his summer house and it is functioning....

I don't mean to distract from the thread and discussion...

I'm impressed. Name dropping and such usually doesn't work on me... but for some reason this does.

I am not an elite hacker. But the guy who told me this also impressed me. I used VAX-11 when I was in college 23 years ago. So I was equally amazed at that he keeps one for himself (employee discount from DEC, I guess) and he has a VT 320 to it.

I am just wondering the kid in India who said he wrote an assembler for PDP-11. I want to know did he verify the code? I wrote an x86 code generator in Ada and that is easy to verify with Linux on PC and I can say it worked. But PDP-11 is kind of hard.

pdp 11 emulators work extremely well. simh is one, supnik-11 is another. Here's a good guide on getting 2.11 BSD running on SIMH:
