22 Oct 16 1. The Computarium acquired a beautiful TODD Protectograph, a device to write tamper-proof checks. See album.

2. Our member Ronny Heinz donated a very nice book "Commodore 64: a visual Compendium" which is another project of the kick-starter company Bitmap Books. This large compendium (474 pages!) has beautiful and stunning screen-shots of many famous C64 games.

Many thanks!

C. Heirendt donated for our "Euro-converter" exhibit an exceptional nice and stylish converter sold as a promotional gadget by Perrier. See album.


16 Oct 16 1. Many updates to the virtual museum, more links to large-scale pictures.
2. Repaired (with C. Heirendt) a miniature Multifix E1R calculator that I drove by careless handling into a completely blocked state. See album of this very nice machine.
21 Sep 16 Pol Hoelzmer contributed again a lot of material; the most interesting object is a rare IBM PC convertible (IBM 5140) from 1986, without power supply but in mint condition. Some soldering to adapt a standard powerbrick, some Internet research to find a PCDOS 3.30, and presto, this laptop is back to life. The IBM 5140 was IBM's first laptop (following the 5155 portable) and sold poorly, due to its difficult to read passive LCD screen and lack of HD (it has only two 720kB 3.5" disk drives). It was designed by the German designer Richard Sapper (see here) and received  many prizes, as the iF Industrie Forum Design Award (Hannover 1988). More pictures in album.

Pol has finished successfully his secondary school studies, and we wish him good luck in his new endeavor!

18 Sep 16 I added a short video  on how to do multiplication on our Everest Multarapid printing calculator, which has a strange dial wheel. We graciously received a manual of the follow-up model from IFHB, which explained how to do the automatic multiplication and cleared up some of our preconceived foggy ideas..
17 Sep 16 Our CH private collection increased by two rather rare sliding rod calculators "made in France": a REBO from 1928 (manufactured in Marseille), and a RAYMOND from 1948 (manufactured in Pernes-les-Fontaines). Click on the pictures for full size views.





13 Sep 16 We received today from the CTIE (Centre des Technologies de l'Information de l'Etat) a very old IBM 3420/6 tape unit from ~1977, which is exposed at our main gallery. The sliding glass panel covering the tape reels was broken during the transportation, and I will try to find a replacement asap. Many thanks for this very nice object! The capacity of this "storage monster" was a max. of 45MB per tape reel. The unit was part of a large IBM 370 system.
12 Sep 16 We bought a vintage OSBORNE 1a portable computer (1982), which is in a very good condition. The CP/M II system disk is easy to duplicate with CopyIIPC.. As there is no application software joined, I will make 5.25" disks from disk image files asap (video). The model is a variant of the first mod.1, distinguishable by the coiled keyboard cable (mod.1. had a flat ribbon cable and can only handle single density (SD) diskettes). The processor is a Z80 at 4 MHz, memory is 64 kB.
01 Sep 16 I am nearly done with the update of the section 3 of our virtual museum (mini/microcomputers). Many new machines were added, and nearly all photos are now originals made at the Computarium. I switched to iSpring Converter version 8.3, which seems to create much faster Html5 code.
This update is heavy work, as the machines have to be cleaned, tested,  opened (to make pictures form the inside, many more pictures are made of each machine than displayed on the web-site) and eventually repaired. There surely remain some errors; please send me an email if you detect one!
29 Aug 16 M. Serge Pletgen, who visited our workshops in Brandenburg, donated two Schubert DRV pinwheel calculators from the end of 1950's. Both needed some work (see here) to come back to working state. Many thanks!  
22 Aug
1. Busy time making pictures of machines, updating the virtual museum and doing repairs.
2. I added to the LIBRARY (PDF section) two files from the Microsoft public archive of the The Computer Museum. These are poor gold: a treasure of original articles and photos of vintage material and computer pioneers. Look here and here (large files!).
17 Jul 16 We participated to the "Branebuurger Maart". More on  "Exhibitions" page.  
20 May 16 Pol Hoelzmer, one of our most prolific contributors, donated quite a lot of interesting stuff: a HP Jornada720 (working), a few computers and many calculators (also all working) with an HP21 among them. As the rechargeable NiCad battery was dead, I carefully slit open the case and replaced the 2 NiCd AA batteries by alcalines: yes this works and does not harm the calculator.! Many thanks!  
28 May 16 André Schwarz is a most prolific writer on computers and the biographies of computer pioneers. He gave the Computarium the full text of all his contributions in the cultural section "Die Warte" of Luxemburg's main news paper "Luxemburger Wort" (which gave us the permission to publish these articles). You will find all the articles in the "Library of the Computarium", PDF section (click here). Many thanks to André and the Luxembourger Wort.  
22 May 16 On this second day Claude Boes, Claude du Fays, Colette Heirendt, Francis Massen and Anouk Neven were present. The attendance was about the double as yesterday, and all visitors showed great interest. Nevertheless we all find that well-needed publicity was nearly absent, as well as the distribution of brochures which went well in Luxembourg-City, but seemed to have forgotten Diekirch; also the City of Diekirch which proudly sells itself as the "Ville des Musées" did not make any visible publicity on the electronic public boards or on its Web site.
21 May 16 The first day of the nation-wide "Invitation aux Musées" day is finished; the number of visitors was clearly enumerable ("dénombrable" in French). We installed everything on Friday afternoon, and Saturday Colette Heirendt, Florence Massen, Ronny Heinz and Francis Massen staffed the show.
Workshops covered Napier bones, Genaille-Lucas rulers, abacus, Logo on vintage BBC Masters. For fun there were some vintage games running on emulators and several original Pong's.
M. Pierre David, a former programmer at EAI (Brussels headquarter) donated a nice EAI slide-rule, some memorabilia and several flow-chart rulers from well-known companies (Bull, Burroughs...). Many thanks!
11 May 16 The LCD Science Déeg had an attendance of about 200 pupils from neighboring primary schools. See album.
04 May 16 Training session with 10 students of the II B mathematical session for the upcoming LCD Sciences Déeg. Colette Heirendt showed how to use Napier Bones and Genaille-Lucas rulers, Francis Massen how to program in LOGO (Turtlegraphics) on vintage BBC Master computers.  
22 Apr 16 Students from an Erasmus+ project follow two workshops on Napier/Genaille-Lucas rulers and Brunsviga calculators in the Computarium. See album.  
20 Apr 16 I found by chance this digital "sliderule" from Lucas-Nülle, a German company which makes educational material, mostly for scientific and technical education. The disc fell out of a journal, probably donated by Jean-Pierre Unsen.

The back side shows the digital states of various flip-flop types.

I did not find a date of manufacture for this nice disc. Any help will be appreciated!

Our regular contributor Pol Hoelzmer donated quite a lot of interesting material, among them a Compaq Armada running WIN96 ! (did you know that this version exists?). See the contributors page for more details. Many thanks!  
30 Jan 16 Yet another restoration: this time a very simple line-tracking robot has been restored. See the WORKS section for more.  
Our member Ronny Heinz participated to the Kickstart project of Bitmap Books to publish a book on the games of the Sinclair ZX Spectrum . This very colorful book is a great pleasure to look at. Ronny donated the book to our library: many thanks!
This is the book #3 of Bitmap Books. Look here for all the books from this company.
