Happy new year!
To celebrate the last night I booted up my PDP-11 in RT-11 and set the date to 31-DEC-99, the last date that that OS can handle without a modern Y2K patch. A few seconds after midnight I checked the time and date. Yeah, that date is broken. Y2K was a real thing.

Sure, you can play games on the C64. Or you can use the 8bit home computer from 1982 as a VT100 terminal for a high performance 16 bit micro computer from 1975 - to play Super Star Trek on a PDP-11/70. "LAST UPDATE 31-MAR 77"😄

PS I am not a technophobe!
I was hacking my way into Unix #PDP11 45 years ago, ran a handrolled fork of #KA9Q on #DemonInternet for a decade, wrote lots of my own software for maintaining a large pre-CMS website etc.
But the #AndroidGmailApp has me beaten. ☹️

Not gonna lie... Dave's fixation with his DEC PDP-11 systems is one of the absolute best things on the modern Internet, bar none. 🫶🏾

Infographic titled “Tech Spec Tuesday – DEC PDP-11/20.” The design features a blueprint-style background with a dark blue information panel. A photo in the upper left shows a Digital Equipment Corporation (DEC) PDP-11/20 computer with its distinctive red and black front panel, featuring switches and indicator lights. To the right, text reads: About this machine: “Introduced in 1970, the PDP-11/20 was DEC’s first in the PDP-11 series and brought an elegant, orthogonal instruction set that influenced many future architectures. With its modular UNIBUS design, it became a popular platform in labs, industry, and education.” A specification table below lists: CPU: 18-bit UNIBUS, discrete TTL logic Memory: 4 KB to 248 KB Storage: Paper tape, later disk/tape systems Graphics: None standard, text terminal output Networking: None standard, serial/terminal interfaces Notes: First PDP-11 model in a legendary line At the bottom right corner is the text vintage.computer.
Introduced in 1970, the DEC PDP-11/20 was the first in the legendary PDP-11 line. Its modular UNIBUS design and elegant instruction set made it a cornerstone of computing in labs, industry, and education. #VintageComputing #DEC #PDP11 #RetroTech #VintageComputer

A 70's era computer programmer seated in front of a hard-copy terminal and display-only VDU is leaning over to alter the address/content switches on the front panel of a rack-mounted PDP-11. He is clearly a geek. The computer is in a psychology department and is networked to twenty or so Skinner boxes. He is a child of his times - long hair, beard, and obligatory hiking boots in case a mountain springs up in the machine room.
Good Morning!

A chunky integrated keyboard system named the PDP-11 personal.
As with my many weird mockups in the past, i made one #PDP11 - themed personal system that has a form-factor like the #appleII.

Dec rainbow logo, but with a purple under-shadow. May give a version to Wikipedia if it's deemed close enough to the original logo.
A logo for a imagined individual/home computer (or in the old days- personal computer) variant of the pdp-11, unlike with the Heathkit H11 the system is preassembled & sold by DEC themselves. Keyboard included with system.
Was on a DEC-influenced logo design creation spree yesterday night. The google logo i posted was from that period too.

Someone extracts the oldest surviving copy of UNIX from the tapes Warren Toomey had been given by Dennis Ritchie in 1997, after Ritchie had already stored them for 25 years (!), and gets a 53 year old operating system running on a PDP-11/20 emulator.
Mindblowing […]

Picture of a DEC10 in large cabinet, and a tty. Text above the image : An all new DECsystem-10, the DECsystem 1080, just set an all new industry standard in timesharing. It's the first system tha t includes every major timesharing breakthrough of the past decade. Yet, remarkably, it costs about half what you'd expect to pay. How did Digital do it? By combining capabilities no one else could combine. Our minicomputer experience, our manufacturing economies, our systems architecture, and our experience of over ten years in large-scale timesharing. So now you can buy a low-cost timesharing system that includes not just one, but all of the following. • A more powerful central system employing mini and microprogramming technology with ECL 10,000 logic, MSI and cache memory. • An integral PDP 11/40 minicomputer dedicated to providing the most comprehensive machine diagnostics. • An advanced Business Instruction Set to handle the most demanding batch and business data processing tasks. • A host of high-performance disk and tape peripherals that facilitate optimum file integrity for most effective data base management, via our new DBMS-10 package. • A completely enhanced operating system offering
Announcing DECsystem 1080.
Every major timesharing breakthrough now in a single system.
DATAMATION Dec 1974

The image shows two mid-aged Caucasian men, likely colleagues or business partners, interacting with early Digital Equipment Corporation computers—a PDP-8 and a PDP-7—in what seems to be an office setting in Maynard, Massachusetts in 1964. The foreground features the men seated at their respective workstations, which include a computer console, a typewriter-like device, and other peripherals, which is common in the workplace of that era. The background is simplistic, with little to no other discernible objects in view, showing a focus on the people and the technology. Both individuals appear to be of Caucasian descent, with estimated income levels between $10,000 and $25,000 per year (in 1964 USD). Considering the era and setting, they are likely Protestant Christians and may lean towards moderate political affiliations. They seem focused and possibly slightly apprehensive as they operate the new technology. Their clothing suggests a business casual style, possibly indicative of their professions as engineers or programmers. Good pastimes might include reading technical journals, attending industry events, and participating in professional organizations. Conversely, they might indulge in less positive activities like excessive work, neglecting family time, and participating in potentially harmful workplace competition. These men, absorbed in their technological pursuits, exude concentration and a certain level of cautious optimism. They present a prime demographic for advanced technology targeting professionals. We can target them with software solutions, office supplies, professional development courses and high-end computer systems near Maynard, Massachusetts, such as Microsoft 365, Lenovo laptops, and online coding bootcamps.
