Please do not treat it as a challenge box; I can restore from tape, but that ruins it for everyone else.
Unfortunately, for a disturbing percentage of the Internet, ruining things for everyone else is the goal. I'd turn off telnet.

A PDP-11 serving adverts for an AI-written site in 2026 was not on my bingo card. Imagine being brought back from the dead for that.

  Unfortunately, this is just Dave "I wrote Task Manager" Plummer's handwriting.

    Wow. I can't imagine the thought process of going from accumulating a decade of Microsoft shares and experience during a pivotal era and deciding to plow it into a consumer scam op.

    for some reason, the tech industry attracts these types like flies to...well, you know the saying. They aren't the majority of folks drawn to tech but outside of maybe finance, it seems to be their preferred habitat.

this appears to just be an ad for some webpage widget-maker.

I posted this to twostopbits. Community over there is small but devoted to such willful acts of restoration

What in the AI slop is this website? Looks like it's trying to get me to download malware.

  Dave Plummer definitely isn't AI.
  - dallen333 hours ago
    He isn't, but nearly everything he puts out there is AI produced. His video thumbnails look awful, and that task manager he built for macOS is fully AI coded. Not saying it's a bad thing, but I dunno it's kinda all ugly looking to me.

I love it. My PDP-11 has some fault that keeps it blowing fuses. Emulators don’t feel the same. Real hardware doing the work, well done

Fantastic build.
Do you know by any chance a source for Q-Bus edge sockets?

Thanks for keeping the spirit of the old internet alive :)
I hope you won’t have to restore it from tape!

Why is the domain `pdp1173.com` when the machine is a PDP 11/83 ?

  There's a couple eyebrow raising things about this post.. like the fact that there's nothing but vague details in text and one photo with an AI prompt like alt-text. I think they're just trying to get clicks for that banner ad.
  - roryirvine4 hours ago
    Sadly, the site does seem AI-flavoured to a rather off-putting extent.
    And, as you say, the details are so vague - it's exactly what you might expect if an LLM wrote them based on reading a spec sheet rather than any practical experience.
    In particular, connecting that DEQNA to a modern network must have been a huge challenge all in itself and I'd have expected there to be a series of blog posts about just that. Maybe it's legit (and I'd love more detail if it is), but right now the presentation screams "thinly disguised ad".

    I think he has actually posted videos of the restoration before (they've popped up in my youtube feed in the past), but I've never watched them, so dunno. The LLM site design and advertisement front-and-center are certainly a... choice....
    But, more importantly, why do you reckon DEQNA would be hard to connect to a modern network? NetBSD still supports it when running on a q-bus VAX: https://github.com/NetBSD/src/blob/trunk/sys/dev/qbus/if_qe....
    It has some pretty broken behavior regarding multicast/broadcast traffic IIRC, but nothing putting it behind a vlan or separate LAN altogether wouldn't solve. I've got a little lsi-11 system under my bed I'm hoping to, one day, get the Fuzzball [0] distribution running on. The 22-bit address extension wirewrap the previous owner did needs to be redone entirely, so it's been a "later" project for years now, but I am hoping my little DEQNA will be able to ping the Internet still.

    I was assuming that something of that vintage would only have been able to handle a 10BASE5 transceiver, but a wee bit of googling suggests that an UTP transceiver works well enough.
    Needs a patched ROM and recompiled kernel, though! See http://www.cosam.org/computers/dec/pdp11-23/20080402.html (and the two subsequent installments)
    (That cosam.org site is more what I'd be expecting for a project like this, but maybe I'm just too old and grumpy for my own good!)

    Dave posts frequently about his work, some on YouTube and some on Facebook. You have to be in the right groups on FB.

    You and several other people here are making unsubstantiated claims about how you're super sure this is real in a way that makes it seem less real. You guys seem to know this Dave character and are doing him a solid, right?

    Dave Plummer's a well known YouTuber. He pops up in a couple of DEC groups that I'm in on Facebook. However I'm not a fan. He seems to take a lot and contribute only self-promotional videos.
    The photo on this page looks very AI heavy. I'm not an expert but I really don't think those light panels are real (if they're real they're not contemporary to the machines they're in).

    While probably it's legit because I've seen Dave discussing the process on the YT channel (which I no longer watch) he unfortunately does have form https://news.ycombinator.com/item?id=39813625
    Having TMOG on a .org when it sells commercial licences doesn't sit well with me given the history.

    Oh, yeah - this popped up on HN yesterday too and also met with scepticism: https://news.ycombinator.com/item?id=49772362
    Oh well, so this PDP restoration probably isn't real. Disappointing.

    What's not real about it?
    ktm5j4 hours ago
    I'm a little confused by your comment.. especially considering the fact that you edited it and changed the link from and old comment thread from 2024 to whatever this dead post is from 2012. What does having form mean? Who is Dave?

    Sorry, lost the last digit, fixed now. This restored PDP-11/83 project is Dave Plummer's
