@robdaemon For some years I had a DEC KL10 (DECsystem 10, PDP-10) in storage that I wanted to run. Where I am now, that would cost $1000/month for electricity, and probably another $300/month for AC. When I was a well-paid software developer, I could have done it, but didn't have time. Now I have time, but not money, and I no longer have the machine. Oh well. At least I have a PiDP-10.
@jfaulken@robdaemon Speaking of which, my friend John and I just finished debugging my PiDP-10. Previously I had some strange LED issues, but it's now fully operational. To facilitate the debugging process, I wrote a program that presents a graphical representation of the console, showing the state of the switches, and allowing individual control over the LEDs. I'll publish that soon.
