Welcome to VAXBARN, Camiel Vanderhoeven's computer collection, located in a 200-year old farmhouse in the tiny village of Netterden, in the east of the Netherlands, on the border with Germany.

There are always various projects that I'm working on that are related to my collection of old(er) computers, and so far, the information about these different projects has always been kept in lots of different places. Since there are a few people occasionally interested in what I'm doing, I've decided to create this website to both document my collection and to have a place to put information about all these different projects in one single place.

Feel free to browse the Collection, or check out some of the projects I'm working on in the menu on the right side of this page.

For any questions or comments, or if you have something you'd like to contribute to the collection, feel free to drop me a note at camiel(dot)vanderhoeven(at)vmssoftware(dot)com.

After the Arrival of the Convex SPP's, and after reading most of the hardware documentation that came with the systems, I worked mainly on the Convex Exemplar SPP-1600/XA for a couple of weekends.

Part of the Vaxbarn collection is what could very well be the largest collection of Convex supercomputers in the world.

The Convex adventure started in 2016 with an eBay advertisement, and since then the collection has seen the addition of 9 Convex supercomputers, spanning three generations of machines.

On Friday, the 11th of May 2018, my friend Andreas drove over from eastern Germany to deliver some Convex SPP supercomputers for the Convex Computer Collection.

I had the opportunity to deliver a lunch-hour presentation about the Convex supercomputers at the OpenVMS Boot Camp 2017. Here's a youtube video of that presentation.

After the Convex C240 Arrived, and the I/O cabinets and spare parts along with it, it was time to continue work on the Convex C220 after the Initial Convex C220 Checkout.

Last Tuesday, Andreas, a friend from Germany, arrived to deliver the Convex C240. Along with the C240 came all the I/O cabinets and devices for the Convex C220, as well as a lot of spare parts (boards, PSU's, drives).

It's time to get serious about putting together a small computer museum, and opening the collection up to the public! If you wish to contribute, please consider making a donation to our GoFundMe campaign: https://www.gofundme.com/vaxbarn

After the Arrival of the Convex C220, I took some time over the course of a few days to figure out exactly what I got, and run some diagnostics. Even though none of the peripherals are here yet (they’ll arrive in a few weeks, along with the Convex C240), there are plenty of things I can do before then.
