New Learning PDP-11 Blog

Hello everyone, hope you’re all keeping safe and well!

I’m a first-time poster here and a recent, but very enthusiastic, fan of the PDP-11. I have started a blog to track my journey of discovery ( and I would love to get some feedback.

There is a lot of information there that I haven’t been able to find anywhere else (e.g. an instruction-by-instruction breakdown of the bootstrap loader and the absolute loader). Right now I’m working on a complete line-by-line breakdown of the PDP-11 BASIC application.

Hopefully it’s a useful resource for those who like getting really low level understanding, like machine code/assembly stuff.

I’m sharing this link here beacuse I thought it might be of interest to some of you and if anyone has suggestions, either for topics you’d like me to cover or…well, anything really, I’d love to hear!




Welcome Dave! Certainly there are some here who share your interests.

For reference, here’s the PiDP-11 groups thread which followed your similar post. (I’m completely happy to see the post in both places.)

Thanks Ed!

Nice to (virtually!) meet you!
