Dave Minter shared his experience in the 1990s with the precursors of modern email, discussion boards, instant messaging, and social systems. He told his story as a student in a DEC-centric world at a UK university linked to JANET and later to the Internet.

Findings at my parents' house, part 3: Two AlphaStations.
They have SCSI disks of different sizes, and the last time I turned them on (2008), they were working perfectly.
They heated the room wonderfully, and the fans were strong enough to move the pictures on the wall 
I haven't turned them on again, but they should still have NetBSD installed.
@kpeace Kinda.
If you’re talking about current #Windows and its NT heritage, it was bought *engineering*, specifically #DEC developers led by Dave Cutler.
Therefore, many elements of #WindowsNT’s design were inspired by DEC’s #VMS, #VAXELN, #RSX11, and (unreleased) #MICA operating systems.
#Microsoft eventually paid off DEC and supported NT on the latter’s #Alpha architecture machines rather than face a lawsuit.

Here's a snapshot from one of our previous exhibitions! 
What do you think of our setup? 
Recently, we welcomed the 🄳🄸🄶🄸🅃🄰🄻 AlphaServer 8400 5/440 into our collection. According to online information, it was considered a supercomputer in 1996 
I didn't realize it at the time but the release of the DEC Rainbow 100 was a big deal back then.
This post explains why and sheds some light on this little known PC, such as the seemingly reasonable design decisions and the market forces that doomed the machine.
https://youtu.be/zcP_Dfgvuo8 ← Here is the video I did with @tastytronic explaining the `HELLORLD!` code, and documenting the entire debugging saga—complete with actual photos of my printouts at the pub, and videos of blinking console lights!
This program is going to be a great basis for a video about how the PDP-12 draws characters on the scope... in short, characters are 6 dots high by 4 dots wide; there are many patterns of 6x2 dots, and letters are constructed by building each character from left and right halves. You can kind of see this in the way that the H has a gap in the middle of it. When I use the "auto single-step" mode on the '12 and slow it down, you can see the characters being written one half at a time.
@spacehobo thank you so much for writing this code, and giving us something fun to run on the '12 and a new thing to describe about how the machine works!
@spacehobo So, I punched your HELLORLD! code you updated according to the actual behavior of the '12 (and now the emulation), and it works! I made some videos that I'm editing down, so stay tuned...!
