| What? | Who? | Description | State |
| Put HP 7585B A0 plotter to work. (06Jul10) | Baumann Claude Massen Francis |
 The big A0 plotter donated by C. Bechoux did its demo flawlessly, but we were unable to drive it from a computer |
Problem solved with new RS2132 cable and many fiddling on the different setup parameters. The plotter works from Windows XP Pro through Roland HPGL drivers or (what is our default) through the Winline HPGL drivers for Windows. |
| Installed
shelves and show cases in the TC. Some more painting and wood work. Started final cleaning before moving objects in. |
Baumann Claude Massen Francis |
The main room is now almost ready. Installation will start in two weeks. Most objects will be installed after the summer vacations (in September-October) | |
| Repaired MADAS 16LS calculator(12Feb10) | Massen Francis | I bought a MADAS electromechanical 16LS calculator on eBAY. It was in a very good shape, but, as common for eBay goods, didn't work. The machine was blocked, one key-columns showed one unit to much (pressing key 1 displayed 2). I dismounted the casing and carriage and with a bit of luck, inspection and WD40 put the whole thing back to correct working. I was unable to complete a division, but this too was solved with the help of Computarium team member C. Heirendt. | Working again 100% |
| Lighting in room #2 of the TC (03Feb10) | Massen Francis Baumann Claude |
We installed the full mounty of all nice lamps of the LCDNB restaurant that I managed to salvage are installed. There was a nasty problem with excessive current (a 132W rated lamp uses ca. 400W) that has been solved through rewiring. | Done |
| Works at the TC progresses as planned. | Massen Francis Krack J-Cl Jean Mootz |
Room#1 is finished, as well as
major repairs in room#2. Approx. 500 working-hours invested up to now. Look at an album here! |
Painting and electrical wiring will be done next. |
| Heavy work at the Thesaurus Computarii (TC), the storage rooms in the attic of the LCD | Massen Francis Krack J-Cl Baumann Cl. |
Provisional gathering of all material in first part of the attic. Wood work, painting, LAN, furniture, lightning. | First room (administration, repair shop, large vitrine...) almost finished (19Sep09) |
| Repaired an Olivetti Summa15 printing calculator (donor: anonymous) which was in a very bad shape. (Feb 09) | Massen Francis | Will be used as an open machine to see working innards | Working again 100% |
| Tested 2 Russian electronic pocket calculators from the Elektronika series. | Massen Francis | No batteries anymore but... | In good shape. |
| Repair in progress on machines donated from N. Friob.(Dec 08) | Mootz Jean Massen Francis |
Many of these machines are not
working. Started with electronic booking machine from Olympia; printing works intermittently, cause as yet unknown. Diehl, Marchant, Facit thoroughly blocked... |
Repair in progress |
| Repaired a Hamann Elma (Dec.08) | Massen Francis | Old Hamann Elma bought from eBay (link to picture, not actual machine!). Was in bad shape. Electrical motor had one missing carbon contact, bearings were blocked. | |
| Restaured Olivetti Divisumma 15 (Nov.08) | Massen Francis | Machine was very dirty, but mostly functional after some fiddling. Cleaned, checked. | Working again 100% |
| TIM UNITAS bought | The AALCD (=Amicale des Anciens du LCD) financed two major acquisitions: a very old TIM UNITAS calculator and a newer Brunsviga D13R dual rotary calculator used in geodesic work. | Both machines working 100% | |
| We made a major successful bid on eBay for about 20 old calculators, all from a single collection. All are in a very "dusty and rusty" state, none is working as is. | Mootz Jean Massen Francis |
Olivetti Divisumma 24 repaired and
working at 98% Olivetti Divisumma 26GT working 100% Rheinmetall printing adder (beautiful old black steel) repaired and working. Facit electromec. calculators (2) partially working Old Olympia calculator with Nixie tubes: no success, but Nixies are lighting up. Also repaired a non working MONROE LA7160 from another bid. |
Ongoing work |

The Cirque des Sciences left us
with a legacy of broken-down machines, which did not survive the children's sometimes brute force |
Mootz Jean Massen Francis |
Several big 4 function calculators
are blocked, as well as a couple of rotary machines. |
Big Friden electromec. and several rotary calculators repaired |
| Building an RS232 interface to connect an old Siemens telex to a PC | Baumann Claude Massen Francis |
Baumann Claude (with minor help from FM) designs a microcontroller (PIC) driven interface; the very complicated programming is made in Labview. The method used is VERY unorthodox! | Telex to PC ok PC to Telex still problems |
| Some pictures of the repairshop |
Massen Francis Mootz Jean |
Many repairs going on. Last success: Cellatron R44SM | Still much to do! |
