Spent some time this monday preparing the machine including installing 2.11BSD to the M2322 hard drive, as my DIY disk emulator showed some reliability issues at #why2025 . I'm still in the process of applying the latest updates to the system, as rebuilding kernels and part of the userland on a 1MB RAM, less than 1 MIPS system takes a fair bit of time.

Once I'm done updating the system, it will be at patch level 499 - the latest available for #211bsd , released on January 14th 2026!

If you want to play around with this system, visit the open day at RevSpace The Hague next saturday:
https://revspace.nl/OpenDag2026

I will be attaching a few physical terminals to it (including a VT55 and VT100!) as well as allowing telnet from the local network.

Besides this, if you do visit and want to trade PDP-11 parts, I have a large collection of mostly QBUS cards that I want to part with, and am looking for PDP-11/84 (PMI) and PDP-11/44 (EUB) memory boards as well as spare CPU cards for the /44.

RevSpace, the hackerspace I'm a regular at, will have it's open day next saturday. I will be exhibiting my PDP-11/84 and possibly work on some other retro hardware as part of this.

Perhaps I'll attempt to repair my 11/44, or show off the VAX-11/750 I keep around there.

They do require visitors to sign up to help load balance the tours of the hackerspace, so check the link below.

Dave y Tara usan una holocubierta basada en Window$ 95 como máquina del tiempo para regresar a 1973 y aprender cómo programar una DEC #PDP11 10 con 32K de memoria de núcleo y sin mouse, y votar a Cámpora! ¡Cargá tu cinta de papel perforado!

Last year, I drew a map of the ARPANET for an event featuring retro and vintage computing. It is based on various previously published maps from 1981, but has been redrawn using a vector graphics software. In addition, I marked computers with DEC PDP-10, PDP-11, and VAX architecture to show their role in the early Internet (there were PiDPs and some descriptions about them as exhibits). It was printed as a DIN A1 poster. Here is the result as a 4k JPEG file. #PDP #PDP11 #arpa #vintagecomputing

Here's a timelapse of me programming a simple counter with a delay loop using the front panel. I entered one of the instructions wrong, so there's a bit of debugging going on as well. #retrocomputing #pdp11

@gmc @freedosproject @FritzAdalis @jmcunx and I just finally got #211bsd running on my #pdp11 (well, pidp11) again. Maybe I can host some of my web site on it...
Another item on my todo list is to get Minix running on one of my #i8088 #pc boxen again, preferably with IP network.

Setup a ProxMox in my server rack for important work, like emulating a minicomputer from 1975. #pdp11 #blinkenlights

Remember me, why else do I need a #pdp11 ?
