Vintage Computing Pages
Since you're here, you are probably looking for vintage computers. I've been a computer hobbyist since the early 80s. Over the years, I've gathered a collection of machines that played a role in shaping the microcomputer revolution. This site is dedicated to them.
​
I also got into homebrewing: designing your own computers. Whatever it is, I hope you find on this site what you came to look for!
Homebrew Computer Kits
The PiDP-1
The beginnings of Hacker Culture
The PDP-1 was a first in many respects. But it is also just an absolute puppy. So simple it is quickly understandable to any 21st century user.
​​
Famous for spacewar, the world's first computer video game, this is the original Hacker's machine - the word comes from its early student users at MIT.
​
Their demo programs are still pure eye candy thanks to the Type 30, a converted radar display. Driving the electron beam over its slow phosphor, pretty graphics effects come out of just a few lines of code.
But this is more than the original democoding platform. It had the first text editor, the first inter-active debugger - even acted as Arpanet's controller.
​​​​
This was a 3-year passion project for Angelo Papenhoff and me, resulting in two versions. The stand-alone 'PiDP-1 Console', and a 'PiDP-1 Rack' version. Both existed back in the day, too. And because DEC could never make its mind up on the front panel color, we gave the PiDP-1 interchangeable white and blue front panels.
The PiDP-10
A faithful replica of the 1968 PDP-10 and MIT's complete AI Lab
My third DEC replica, and quite a special one. A computer History Capsule!
​
It gives a hardware shape to the ITS Reconstruction Project (link).
So, yes, it is a fully functioning replica of the 1960s PDP-10 mainframe. It will run DEC's own TOPS-10 operating system.
​
But it also includes tons of additional hardware, as found in MIT's famous AI Lab.
​
And the PiDP-10 also runs the reconstructed ITS operating system, that was developed at MIT by hackers - the only hackers at the time who could play with a computer of this size and power.
Hundreds of important, interesting and simply fun programs were written for it, making the PDP-10 the only mainframe ever that is just fun to use...
The PiDP-11 kit
A faithful replica of the 1975 PDP-11/70
The PDP-11 was a hugely significant computer. Its architecture influenced pretty much every CPU and computer designed afterwards. It was also the first machine for which you could buy Unix...
The PiDP-8 kit
A faithful replica of the 1968 PDP-8/I
The 8/I is the favourite computer I never had... And by now, real ones are impossible to obtain. And to maintain. So the PiDP-8/I has become my 2015 replica project.
​
The PiDP-8 is a true 'computer history capsule': it comes with a huge amount of software and operating systems ready to boot. Visit the Google Group for lots of PDP-8 developments!
The KIM Uno kit
A homebrew clone of the vintage KIM-1
The KIM Uno is a calculator-sized board based on an Arduino Pro Mini. It emulates the KIM-1, with a lot of vintage programs ready to run in ROM. It's also extended with a calculator mode, that turns the venerable KIM into a 6502 programmable calculator.
Perhaps you are not looking for computers at all... If you are the proud owner of a Hurley sailing boat you may be looking for its documentation archive - that site, by now more than 17 years old, is below along with various other curiosa I picked up along the way...
