RE: https://hsnl.social/@revspace/116256653592044537 RevSpace, the hackerspace I&#39;m a regular at, will have it&#39;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&#39;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. #revspace #hackerspace #netherlands #thehague #retrocomputing #leiden #pdp11

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. #pdp11 #retrocomputing #unix #revspace #minicomputer
