Catch of the Day: A Dinosaur on the Web – OpenVMS on a VAXstation! 🦖
Hey Retro Fans!
When we think of retro computing, most of us picture a beige tower PC, a C64, or an Amiga. But yesterday, our bouncer welcomed a true heavyweight from the depths of professional IT history:
VMS_Mosaic 4.0 on OpenVMS V7.3 (VAXstation 4000-VLC)!
Let that user agent sink in for a moment. DEC (Digital Equipment Corporation) was once a giant of the computer industry. Their VAX architecture and the accompanying OpenVMS operating system are absolute legends, famous for a level of stability that modern systems can often only dream of.
The VAXstation 4000-VLC ("Very Low Cost") hit the market in the very early 90s—a compact UNIX/VMS machine for professional use. The fact that someone in 2026 fires up this machine, launches the graphical Motif interface, and browses FrogFind using the native VMS_Mosaic browser is absolutely mind-blowing. It proves once again: With the right bridge (and FrogFind!), no architecture is too old for the internet.
A reverent toast to indestructible DEC hardware!

From Paul McJones on LinkedIn:
Most people are familiar with Niklaus Wirth's sequence of languages [EULER, PL360, Algol W,] Pascal, [Modula,] Modula-2, Oberon. But a parallel sequence, designed at #Xerox #PARC and #DEC System Research Center, is not so well known: MPL, Mesa, Cedar, Modula-2+, Modula-3. I … decided to capture as much of the history as possible of these "shadow" languages:
MPL/Mesa/Cedar: https://lnkd.in/gnUa6WU6

Внутреннее устройство ОС RT-11: копаемся в исходом коде. Часть первая
RT-11 — это операционная система из 1970-х годов для популярного в то время мини-компьютера PDP-11 фирмы DEC. В СССР известна под именами Электроника 60, ДВК, БК 0011М. Для тех, кто любит изучать чужой код в поисках инженерной эстетики — дальнейшее изложение.

Occasionally I work on my PDP11/70 emulator (toy-project, in my spare time). The latest version can run BSD 2.11 multi-user on an ESP32-S3. Even though I wrote the emulator myself, I'm still amazed about the physical reduction in size. On the left in the picture below you see the original device (the thing in the 19" rack with all the lights and switches), on the right you see the ESP32: smaller than my hand!

This is still my favourite personal hackery/security story, and the only one I have ever written about where I am on the naughty-side of the desk.

In the late 1970s Interlisp was ported to DEC VAX computers under Berkeley Unix. These papers reported on the project and its challenges.

I sort of miss programming on a DECwriter (teletype). There was something satisfying in literally pushing a key down and seeing punch-paper tape spew out. You were creating something. Now, everything you do is just feeding an LLM without any real result.

Trying out #Mastodonochrome by @simontatham on my trusty old #DEC #VT420 terminal.
Generally works ok, but all normal text is flashing for some reason. And it's not respecting my ISO-8859-1 codepage preference.
But it's fun that it's running at all! It does have a #BBS feeling. 😄

Bitsavers posted several transcripts of DEC oral history interviews with company leaders, engineers, and researchers such as Ken Olsen, Gordon Bell, Butler Lampson, Bob Taylor, and more.

Boards of Canada - Olson, on a PDP-1 from 1959. 🎶
”The PDP-1 was never intended to produce audio […] It does however have six "program flags," which are flip-flops wired to six light bulbs on the control panel. A CPU instruction provides the ability to turn these light bulbs on or off via software.”
