This one might be interesting to anyone interested in computer gaming history.
I spent the last couple of weeks finally finishing a project I started for Bletchley Park about 20 years ago. Recreating the original MUD (AND the MIST) on a mirror of the original Essex University system that finally closed in 1991.
Roy Trubshaw and Richard Bartle wrote the first online multi-user game (MUD) on Essex University's DECSystem-10 in 1978 and it ran till I closed it in 1991. I diligently backed everything up so I could potentially recover it one day, but as far as I can see, all the DECSystem-10's went to the great scrapyard in the sky, my backups were mostly stolen when my first museum was stolen, and I had huge issues recovering the Essex BCPL compiler to compile what I had left when I finally got a decent TOPS-10 emulator running on a VAX for Bletchley Park.
One good thing about being an unemployable whistleblower is free time, so I finally hunkered down to some 90 hour weeks and built a software replica of the Essex system I think reflects it well. It's running on a KS10 not a KL10 but I had to let some things slip.
I put the latest known versions of MUD and MIST on it, and miraculously found ROCK too.
So, to meander to the point, if you want to see and relive exactly what online multi user gaming was like from 1978 to 1991, you can go to https://dec10.uknet.net and login as guest, then follow the terse instructions from there.
In those days, you were generally faced with a "." prompt and left mostly alone, so for authenticity, I will leave it at that.
I should note that this is a museum peice, without a community they are still wildly popular games with a huge community in snapshot-form at the moment. But I will leave them up and running to see. I wasn't going to, but Richard seemed happy to have MUD running, and former MIST players wanted it back, so...
Pop this a share if you know folks who might be interested.

I am happy with this DECSystem-10 MUD system for now; it's been a 35-year task.
If anyone is bored enough to be curious!
31 January 1991: Essex University's DECSystem-10 closes, meaning that MIST and ROCK, and the dodgy version of MUD we had on there, had to close. I had a mostly working VMS system that would run it with some extra programming, but I'd already sent out AberMUD to Vijay, and he'd sent it out to the world, and TinyMUDs were becoming common. MIST was losing its captive audience, and it needed that level of addiction and co-dependence to run, so I decided to let it die in its prime, rather than become a sad old relic that nobody played.
Sometime in 2004/2005 and the next 20 years: I decided to build a TOPS-10 system on a VMS machine and install MIST/MUD and ROCK. Got quite a long way, and then discovered there was no BCPL compiler existing anywhere in the known world. A few years later, Richard Bartle told me that Paul Allen (I think) had found one. So this became possible, and Quentin (dot-co-dot-uk) took a great stab at it with some really old code, and Viktor Toth had BL running, so I figured that was enough. Sometime in this period, Bletchley Park got something that looked like a PDP-10, and they suggested that I go and put MUD onto it for the museum. It wasn't a PDP-10, but I did look into putting it onto a VAX for a while, but the management of Bletchley, as it turned into The National Museum of Computing (TNMOC), was getting more corporate and boring, so I gave up bothering.
19th Feb to 22nd Feb, 2026: I decided to build a PRIMOS machine on a Simh emulator for no apparent reason. It went fairly smoothly, so I wondered again about a DEC-10. I was missing TOPS-10 anyway, so why not? Proof of concept, setting up some test systems, seeing where TOPS-10 emulators were at these days and seeing how far Quentin had really got and how much extra work was needed. Realised I am going to have to start from scratch, mostly, using a prebuilt Steuben distro of TOPS-10 7.03 as the base.
Took a couple of weeks off to ponder whether the rest was worth it, but decided my $200 a month ChatGPT Pro subscription may as well pay for itself with background research, so I decided to go ahead.
9th March 9 to 18th March, 2026: A long spring, and I mostly got it all working. 92 hours of concentrated swearing and about 15 hours of destroying the planet with GPT Deep Research mode later, after at least 2 false starts and complete wipes. I got a system I am relatively happy with. Somewhere in there is about 4 hours of relearning TECO and fighting with getting ROCK working on code it was never meant to work on. There's still more to do, but that's just maintenance now.
BUT I FOUND ROCK! I thought it was lost forever. Somehow, that's my major victory in all this. Building the setup was hard, tedious, and very frustrating work. It probably did need somebody who knew a lot about both DEC and Unix systems management, and the MUD engine, to guide it, but it was still mostly a matter of putting together things that already existed and forcing them to work together. ROCK, though, I genuinely thought was 100% lost.
It's taken a hundred plus concentrated hours, two new dedicated hosts, a small town's water supply, and probably a few megawatts of power in the background. But this is the final re-creation of the systems I closed at the start of the 1990s.
MIST (and MUD and ROCK) will still probably end up as relics that nobody properly plays, but this project is not pretending to be anything other than an interesting throwback and museum piece now, which, 35 years after I closed it down, seems a fitting end. It also means I can resurrect Duncan Rogerson's arch-wizard, and that seems right, somehow. I will leave it up and running now.
