His love of VAXen

My longtime friend and acquaintance, Dr. Bernd Ulmann, Once had so little space in his home that he had to sleep on top of the machinery he had rescued. Dubbed, "The VAXMAN" by a visiting friend of his, the name stuck, and to this day we have an awful lot of history that would otherwise not exist - but at great personal sacrifice and expense I might add.

Here's but a taste of the vagaries that cometh your way when you indulge yourself in a (worthwhile) labor of love, one that is now shared with people worldwide, but nevertheless not without great, unforseen difficulties:

Since the warehouse was quite filled with computers I asked the company to place the tiles into the cellar and decided to bring them up into the first floor when I began to glue the supports to the floor. I never thought that 5 tons of floor tiles would be so heavy! One tile weights about 13 kg and at the beginning I carried two tiles at once (by the way - to bring something up from the cellar one has to walk around the warehouse - there is no direct in-house connection) - after some time I carried one tile at a time and after two days I could barely walk with a floor tile in my hands. By the way - the special glue to fixate the support stands to the floor is a fantastic glue - it glues shoes as well to the floor as gloves, hands to gloves, everything to everything.

We won't even go into the precarious rebuild of the roof or subsequent repairs, or the catastrophe that resulted in a hockey rink in and around dozens of vintage computer systems when a water main broke whilst he was away attending a conference in the United States (Ouch!).

You can indulge yourself in the magic that resulted in his Computer Museum HERE

There's got to be one of those laws that goes something like, "Everything always runs just fine until you close and lock the door behind you for the weekend getaway"

If there's truly an attribution for that phenomena (that everyone of us knows all too well) then do let me know!

Needles to say, he know longer sleeps atop PDP-11 systems, and I think his wife Rikka had something to do with being the motivational force in the commissioning of the wonderful computing museum, effectively putting an end to his bachelor life sleeping with VAXen.

Today, Prof Ulmann is a Professor of Business Informatics at FOM University in Frankfurt, Germany (FOM Hochschule für Oekonomie und Management). His computer museum is located in Heidenrod-Kemel, in the state of Hesse, and I believe it is still welcoming visitors by appointment.

In 2023, Dr. Ulmann founded anabrid GmbH in Berlin, continuing the pursuit of his decades long passion that predates his undergraduate years - analog computing, and even its place in the application of future AI, as demonstrated in his most recent published paper HERE. As a semiconductor company, One of the obvious missions of anabrid is the manufacturing of analog computers on a chip - beyond the bleeding edge, actually.

You can browse his Analog computer collection online HERE - it's a truly amazing accomplishment, even for the lay-person to behold. Truly.

Bernd Ulmann, a remarkable steward of computing history and visionary pioneer in the applied sciences of analog computing.

Before you go you should know...

- Hey heads up everyone! I'm preparing to launch my subscription based service here, publishing unique and newsworthy insights into technology, cookbook style tutorials and howto's and things I find personally amusing and worthwhile, from the PoV of an opinionated and accomplished member of the technology sector since 1977, when I only spoke BASIC and COBOL.
- If you're interested, subscriptions are at or just below $10 USD per month - give or take - I only accept Monero ($XMR), so I"m obviously not doing this to pay for my solo-circumnavigation of the globe in an inflatable dinghy, but there are plenty of places I can spend Monero for supplies and services, which Others will be happy I did as well.
- If you would like to subscribe, but cannot find the #crypto in your pocket, on a case by case basis you can just ask for me to publish a particular article for you, and I'll more than likely be happy to do so, since the point isn't to make money, but the value in the effort and to promote the use of Monero as tender. Or, alternatively, you can wait a few months and I usually, eventually publish my articles elsewhere (mostly the tutorials, because they have the greatest value for helping people with particular projects and problems.
- So how will you know about any particular article? Easy! I publish a teaser, you know, a few lines or paragraphs of a topic and then one of those "READ MORE HERE..." things leading you to the full article, tutorial, or How-To of general interest. That link of course, only works for subscribers, and therein lies the value of subscriptions - and it's a good cause too. #FOSS is freedom, and #Monero supports that ethic.
- Not to worry! I'll still be publishing the same old drivel as usual, but I've been putting some finishing touches on the first lot of items that will be exclusively curated for subscribers. At less than the cost of two fancy foo foo coffee drinks at that Seattle based retail chain, go ahead! Give it a spin :)

** If you've got any ideas or requests, I'm down on doing the research too, so don't hesitate to ask, as long it's not centric to ewb00ntew, because frinds don't let frinds run ewb00ntew.
