Finally I’ve got around to tinkering with DECnet for Linux (again!). DECnet had been in the Linux Kernel for a long time, but very few people used it. This probably explains why it was marked as “orphaned” in the kernel in February 2010. As I’ve not had any success getting it to work on any […]

I recently bought a Barracuda 300 Spam Firewall Appliance on eBay for about £20. That pittance got me an AMD 64 LE-1300 with an 80GB SATA HD and 2GB of memory in a 1U rack mount case. The idea was to install Ubuntu Server 16.04 LTS (64 bit) on it, and use it as my […]

I’ve never used RSX-11, or a real PDP, so for once this little project isn’t a pointless trip in to nostalgia-land, but a genuine attempt at me trying to learn something new (old actually). I have no use for an RSX install (unlike the VMS and Ultrix installs, which I actually use), so this is […]

It has taken a while, but I’ve finally got around to trying DECnet for Ultrix 4.0. For this you’ll need an image of the DECnet for Ultrix 4.0 install tape [here] You’ll also need a license to use it. You can find one if you look hard enough on t’internet but I’m not going to […]

Sometimes, running a full system emulation is nice, but overkill. Maybe you just want to run a few cherished programs, rather than relive the whole glory/horror of an ancient system. Maybe you once wrote a really atrocious text adventure for CP/M 2.2 on the Amstrad PCW8256, and want to reminice every ten years. If so, […]

I’ve thought long and hard on this one: SimH runs under Linux, and Android is based on Linux, so can you run SimH, and thence a simulation of a VAX, on an Android phone/tablet? Well, obviously you can, but it really is a bit of a fiddle. There is an Simh Android App to do […]

Remember the old AberMUD game? I wasted many hours on it back in the early ’90s. And now I’m wasting more… I’ve got an instance of AberMUD up and running at mudbox.recondite-computers.co.uk. You’ll need an SSH client to access it though. The username and password to login are both “mud”.

For a while now, Jim Wilkcoxson has had a variety of PR1ME Emulators running on his site. They can only be accessed by telnet and the software is not freely available. To access them, telnet to  em.prirun.com 8001 Login as user “guest”, password “pr1me” After logging in, use the Prime HELP command for assistance. You […]

What is HECnet? HECnet is a DECnet that connects different people who play around with different DEC machines. The network should not be regarded as a serious networking setup, nor should it be expected to work 24/7. It’s a hobby project between people who think it’s fun to create a DECnet network. HECnet is basically […]

I’ve had a look at getting an old copy of ULTRIX (Unix for the VAX) running. Having already got Simh up and running, I just cloned the SD card from the VMS host and deleted the VMS specific bits, copied across an image of the Ultrix 4.0 install tape, knocked together a shonky .ini file […]
