Welcome

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.

Saving private Cossor

About a month ago, a French colleague of mine drew my attention to a french website, the title of which translates to "Private Cossor must be saved". A Cossor DIDS-400 terminal of the mid-1960's was going to end up in the trash unless someone stepped up to rescue it.

Fixing and Booting the SPP-1600/XA

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.

The Convex Computer Collection

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.
