Almost done with assembly of the #PiDP-11 (PDP-11/70 replica) kit. Still waiting for some connectors to arrive from #Adafruit for the back panel that bridge to those on the Pi inside.

Booted up into RSX-11M-PLUS, an OS I haven't touched since high school. As the Pi on the inside is connected to my wifi, I'm able to SSH into the console and login as SYSTEM (lol).

Progress on the #PiDP-11 kit last night.

The Raspberry Pi 3 A+ has been loaded with the #SimH software and various bootable OS images that can run on the PDP-11/70. Connected it to the GPIO interface on the back of the PCB where it will live. Powered it up for a "smoke test" and let it boot into the default "idled" program that runs some patterns on the LEDs.

Then inserted the panel switches and got them soldered in.

A while back, I stumbled onto Oscar's #PiDP-11 kit, a 6:10 scale replica of the PDP-11/70. As a fan of #RetroComputing, I decided to buy the kit and attempt to build it. It's powered by an RPi running #SimH, which gets wired up via GPIO to the front panel switches/lights, faithfully reproducing the functionality of the original.

Finally started building this evening and, after about an hour, managed to get all the diodes and resistors soldered on and the LEDs staged.

One of the very few perks of working in public education is the amount of time off. Christmas break is all of next week and I think I need a project. Bumping the PiDP-11 up to the top of the list. Gonna finally assemble that thing. #pdp-11 #pidp-11 Photo blatantly stolen from https://obsolescence.wixsite.com/obsolescence/pidp-11
