The PDP-11 and the roots of Linux

Let's explore UNIX on the Digital PDP-11/70 and the Emulator simh. We will mimic the original hardware using the PiDP-11 kit at about 1/10 the size, 1/50 the weight and 100x the capability. At probably way less than 1% of the price. We will take a look:
* The original PDP-11
* UNIX on the PDP-11
* Building a PDP-11 emulator with the PiDP-11
* Open Source simh
* Serial Terminals and other fun things.

Dwain Sims has been attending TriLug since 2008. He became a Triangle resident in August 2000, relocating with his wife and 3 (now 4) kids from the Bay Area in California. Dwain has a Master's Degree in Computer Science from West Virginia University, and has worked for so many companies that it's getting hard to count them. Among these were Lockheed, Sun Microsystems, SteelEye Technology, Fusion-io, SanDisk, and finally SUSE where he started in 2018 and retired in January 2025. Dwain and his wife Cleo have been doing some traveling (Florida, California, and Alaska in 2025) and are looking forward to their first granddaughter who should arrive this summer.

As usual, pizza and beverages will be provided and the meeting will be held at the North Carolina College of Textiles, room 2207, 1020 Main Campus Drive, Raleigh NC, 27606 at 7:00 PM.

There is an underground parking deck next to the College at the Monteith Engineering Parking Deck. Parking is free after 5 PM.
