With the PiDP-1 coming soon, should I start a PDP-1 assembler course, i.e., a related series of blog posts?
Is there any interest?

Very much looking forward to building the new PiDP-1 Rack kit that’s just arrived 😍 @oscar-ceds.bsky.social

Progress on the new #PiDP-1 (logically, the new PDP-1 replica) is sufficient to open a Hackaday project page for it: hackaday.io/project/2025...
One more month, is the idea, and then it is done! Angelo and I will be doing a two-week sprint that should tie up all the loose ends in April.

Replica of the PDP-1: PiDP-1
The DEC PDP-1 was, in many ways, at the root of modern computing: interactive - with keyboard and graphics display. It spawned spacewar, the very first computer video game; teco, the first text editor...

The DEC Opcodes app just got a nice update. Learn how to write low-level code on mini and mainframe computers; now with PDP-1 and PDP-8 programming tutorials. Especially useful if you have a PiDP-1 or PiDP-8!

<p>We spent the last four days investigating how we can bring our PiDP-1 on Arpanet. Yes, really. Because (1) there is some major history there, and (2) there's a major new project from Lars Brin...

I love that aesthetic so much. I mentioned it in another thread but here's the PiDP-1 finally finished and fully operational.

Bon j'ai craqué, histoire d’égayer ce triste début d’année je me suis offert un PiDP-1 🤩

You may have seen this already, but there’s a PDP-11 replica that can be driven by a Pi, you can get it in kit form or they will pre-assemble it for you for extra.
All those switches & lights, dreamy…
They also have PDP-10, 8 & 1 kits.

Isn't it beautiful? I've added another member to the vintage computer replica family. The PiDP-1 now joins the 10 and 11. Man, computers back then had style.

In case anyone here didn't know...you can get your own PDP-1 replica: obsolescence.dev/pdp1.html . The Pi that runs the simulator also emulates a Type 30 oscilloscope display, and you can play music on it as well.
All of Oscar's kits are great.

In anticipation of the upcoming PiDP-1, I revisited my "Ironic Computer Space Simulator" (ICSS), a "Computer Space" simulator for the DEC PDP-1, written in 2016.
Sense switch options now default to recommended settings and the score display options have been reworked.
