Mostly computer thought's and stuff I've done!
I don’t know if I ever documented this or not. But back in college we had a PDP-11/40 (or maybe 45). Some courses required a computer credit. The main computer courses were on the IBM mainframe. That probably would have been a steep introduction to computers. Programs were punched to cards, then read by a …

The PiDP-11 manual has instructions for running the software without the front panel. However starting RSTS/E took almost an hour. So I posted the problem on the PiDP-11 google group. Oscar suggested commenting out starting the server startup in /opt/pidp11/bin/pidp11.sh Here is a part of the script with the server commented out This. made a …
I always wondered why smh pegged the CPU. But as I was reading about FOCAL-69 on the PiDP-8 they showed a command set cpu idle. There were other interesting commands. See PDP-8 on simh below. Anywho I added it to my RSTS/E games.ini and no more pegged CPU.
I stumbled upon this demo today. It was interesting because it shows how the PiDP-11 software reacts to the panel switches. At around the 4:55 min mark.
Nothing technical on my part. I just copied and ran this. From these instructions. FOCAL-69 from paper tape image. Still…as a fan of DEC…cool to see this. $ pdp8 PDP-8 simulator V3.8-1sim> load focal69.binsim> run 200_TYPE “HELLO, WORLD” HELLO, WORLD* As mentioned from those instructions, several software kits available to run on the PDP-8 and …

So I have this crazy idea to build a PiDP-11/70 front panel…kit. But I’ve never soldered before. And that makes me nervous. If I could buy it built…I would. So I was looking for something cheap to practice on and found this (only $6)… Which like the PiDP-11/70 has a lot of LEDs (but not …
Found out about this new (to me anyway) video community based on peertube. Read about it here. He says… it’s part of the Fediverse (so you can follow a channel on Peertube straight from Mastodon for example). Sounds interesting.
Found this interesting, something to keep my eye on.
