FINALLY succeeded in getting an Ethernet-adapter emulated in my PDP-11/70 emulator. With NAT (port-)forwarding it runs a tiny http-server connected to the internet. Reachable via http://188.212.113.203:8080/
Note that it is not very stable yet so it may become unreachable suddenly. No https or ip6 as the whole http-server should fit in less than 56 kB of RAM. -

Внутреннее устройство ОС RT-11: копаемся в исходом коде. Часть первая
RT-11 — это операционная система из 1970-х годов для популярного в то время мини-компьютера PDP-11 фирмы DEC. В СССР известна под именами Электроника 60, ДВК, БК 0011М. Для тех, кто любит изучать чужой код в поисках инженерной эстетики — дальнейшее изложение.

Occasionally I work on my PDP11/70 emulator (toy-project, in my spare time). The latest version can run BSD 2.11 multi-user on an ESP32-S3. Even though I wrote the emulator myself, I'm still amazed about the physical reduction in size. On the left in the picture below you see the original device (the thing in the 19" rack with all the lights and switches), on the right you see the ESP32: smaller than my hand!

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/OpenDag2026I 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.

RE: https://hsnl.social/@revspace/116256653592044537
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.
