| 1991 ? | MY FATHER, A PROFESSOR FOR PHYSICAL CHEMISTRY AT THE ALBERT LUDWIG UNIVERISTY OF FREIBURG, HAD TO |
| | MOVE WITH HIS LABORATORY (CONTAINING AMONG OTHER STUFF BIG FAT ESR MAGNETS) TO A NEW LOCATION. IN |
| | THES NEW ROOMS THERE STILL WERE ALL THINGS OF THE LABORATORY, WHICH WAS LOCATED THERE BEFORE. |
| | IT WAS THE LASER SPECTROSCOPY LABORATORY OF PROFESSOR SCHMID. |
| | A FEW DAYS BEFORE MOVING IN, MY FATHER TOLD ME ABOUT THIS LABORATORY, AND THAT THERE WAS ALSO A VERY |
| | OLD COMPUETR. AT THE LATEST OF THIS POINT I BECAME VERY CURIOUS ABOUT THAT LABORATORY AND I CAME |
| | ALONG TO VIEW ALL THAT... |
| | |
| | IN FACT THERE WERE SOME LASER UNITS (ABOUT 1.5 METERS LONG), WHICH WERE BURNT OUT. MY FATHER TOLD ME, |
| | THAT THE FLUID COOLING SYSTEM CONSISTED OF TWO DIFFERENT METALS (ONE BASE, ONE NOBLE), WHICH THEN |
| | DID OXIDATE SOME DAY, AND BY THIS ALL LASERS BURNED OUT. BUT THIS HAPPENED YEARS BEFORE... |
| | |
| | FOR MEASURING AND PROCESSING THE DATA OF THESE LASERS, THERE WAS A COMPUTER SYSTEM CONSITING OF FOUR |
| | RACKS. A DEC PDP-8/L WITH AN A/D CONVERTER (I THINK IT WAS A DEC AX08) COLLECTED THE DATA AND STORED |
| | IT. A DEC PDP-8/E WITH TWO DISK DRIVES PROCESSED THE DATA AND MADE IT VISIBLE ON SOME PLOTTERS AND |
| | A CUSTOMIZED CRT TERMINAL. I CANOT REMEMBER THE COMPLETE SETUP, OR HOW WAS THE DATA EXCHANGE BETWEEN |
| | BOTH PDP-8 COMPUTERS BUT EVERYTHING WAS HOUSED IN FOUR CABINETS, WHICH WERE SURROUNDED BY A LARGE |
| | WOODEN BOARD, WHICH SEPARATED THE LABORATORY FROM THE COMPUTERS AND THE AIR CONDITION FOR THESE... |
| | |
| | BY THEN I WAS LIVING AT MY PARENT'S HOUSE, AND WHEN I TOLD MY PARENTS I WANT TO BRING THE COMPLETE |
| | COMPUTER SYSTEM HOME, THE ANSWER WAS NO! THE NEXT PROBLEM WAS, THAT A SCRAP DISPOSAL COMPANY SHOULD |
| | CLEAR THE LABORATORY ROOMS WITHIN THE NEXT DAYS! SO I STARTED A CRAZY RESCUE CAMPAIGN. I SAVED ONE |
| | CABINET (WHICH MY PARENTS FINALLY ALLOWED ME FOR MAXIMUM) WITH THE PDP-8/E , WITH THE DECTAPE UNIT, |
| | BOTH DISK DRIVES AND THE FPU, ALL 110V TO 220V CONVERTERS. THE PDP-8/L WITH ITS MEMORY EXPANSION, |
| | THE HIGH SPEED PAPER TAPE UNIT AND THE TELETYPE ASR 33 AS WELL AS THE VOLTAGE CONVERTERS ALL |
| | DOCUMENTATION, PAPER TAPES, DECTAPES, AND A SPARE PDP-8/E CPU I BROUGHT AT HOME STEP BY STEP, SO MY |
| | PARENTS COULDN'T SEE... |
| | |
| | ALL IN ALL I LOST THREE CABINETS, ONE DECTAPE UNIT, THE A/D CONVERTER, PLOTTER AND UNFORTUNATELY THE |
| | THE TERMINAL TOO, WHICH WAS CUSTOMIZED TO SHOW GRAPHICS! BUT BACK THEN I HAD NO OTHER POSSIBILITY... |
--------------------------------------------------------------------------------------------------------------------
| | THIS IS THE PDP-8/L WHICH BELONGED TO THE DATA COLLECTION SECTION. IT STILL HAS A MEMORY EXPANSION |
| | (BM8L), HIGH SPEED TAPE READER/ PUNCHER AND A TELETYPE. ORIGINALLY IT WAS SHARED OVER TWO RACKS AND |
| | HAD AN A/D CONVERTER AX08 AND A DECTAPE UNIT. |
| | MANY DOCUMENTATION AND SOFTWARE ON PAPER TAPE AND DECTAPE ARE ALSO EXISTING. |
| | THIS SYSTEM IST STILL LOCATED AT MY PARENT'S HOUSE NEAR FREIBURG... |
