OTTO MÜLLER WAS WORKING AS AN ENGINEER AT TELEFUNKEN, WHEN HE MET ILSE ANGSTENBERGER - HIS BRIDE-TO-BE IN 1957. HE WAS PROUD TO WORK ON A BIG PROJECT OF A BIG COMPUTER FOR SCIENTIFIC STUDIES OR WHAT ELSE, WHEN SHE ASKED HIM, WHETHER HE COULD DESIGN A VERY SMALL COMPUTTER FOR WORK IN A OFFICE, BECAUSE SHE DISCOVERED, THAT ALL OVER IN BUREAUS LOT OF PEOPLE HAS TO DO LOT OF DUMB, REPITIVE WORK EVERY DAY, WHICH COULD BE DONE BY A (SMALL) COMPUTER, IF IT WOULD EXIST.
IN FACT NO OFFICE COULD AFFORD A COMPUTER - AS IT WAS BUILT AN SOLD THESE DAYS. SO ALSO OTTO MÜLLER TOOK A SHINE ON THIS IDEA, AND BOTH DEVELOPED THE MORE OR LESS THEORETICAL (ACCOUNTING) OFFICE COMPUTER AND GAVE HIM THE NICK NAME "TR X".
IN 1961 THE WORK ON THE TR 4 WAS FINISHED, AND SO THE COUPLE - ILSE AND OTTO MARRIED TWO YEARS BEFORE IN 1959 - TRIED TO CONVINCE TELEFUNKEN, THAT THERE IS A NEED FOR SMALL OFFICE COMPUTERS. OTTO HAD DESIGNED GREAT PLANS IN HIS SPARE TIME AND OFFERED THESE TO TELEFUNKEN, BUT THE CHIEF EXECUTIVES DID NOT REALLY BELIEVED IN THE SUCCESS. HOWEVER A PROTOTYPE - THE TR 10 - WAS BUILT AND INTRODUCED ON THE HANNOVER FAIR IN 1963.
THIS CONVINCED SOMEONE ELSE: HEINZ NIXDORF, WHO WAS LOOKING FOR A NEW PRODUCT AND A GREAT ENGINEER, WHO COULD DESIGN IT, AND SO HE PERSUADES OTTO MÜLLER TO REALIZE THE TR X AT NIXDORF.
THE PROGRAMMABLE CALCULATOR "LOGATRONIC" SOLD BY WANDERER AND BUILT BY HEINZ NIXDORF'S LABOR FÜR IMPULSTECHNIK WAS ENHANCED BY MÜLLER'S DESIGN IN 1965 AND THEN WAS ADVANCED TO THE FIRST SMALL ALL PURPOSE (OFFICE) COMPUTER IN 1968, WHICH WAS BUILT AND SOLD BY NIXDORF COMPUTER AG AS THE WELL KNOWN NIXDORF 820 (12-BIT, MICROCODE CONTROLLED).
OTTO MÜLLER SOON UNDERSTOOD, THAT THE COMPUTER TECHNOLOGY IS A FAST ALTERING MATTER, AND SO HE SOON DEVELOPED A 16-BIT VERSION OF HIS COMPUETR AND SHOWED IT TO HEINZ NIXDORF IN 1968. BUT NIXDORF DIDN'T SAW THE NEED FOR THIS - PROBABLY BECAUSE THE 820 WAS SUCH A BIG SUCCESS, AND HE COULDN'T IMAGINE THAT THIS WOULD CHANGE.
SO OTTO MÜLLER LEFT NIXDORF COMPUTER AG DISAPPOINTED AND FOUNDED THE ENGINEERING OFFICE "COMPUTERTECHNIK OTTO MÜLLER" IN 1969. HE ALSO TRIED HIS LUCK IN THE U.S. WHERE HE COULD DEVELOP A PROTOTYPE BOARD OF HIS 16-BIT COMPUTER CPU IN A CALIFORNIAN COMPANY (ISI (DURA) LATER ITEL). BUT BY 1970 IT BECAME CLEAR, THAT MÜLLER GOT INVOLVED INTO COMPANY-POLITICAL TROUBLE AND SO AGAIN HE LOOKED FOR POTENTIAL BUYERS IN GERMANY - AND FOUND THESE IN TRIUMPH ADLER!
HAPPY TO EARN SOME MONEY THE MÜLLERS WERE ASTONISHED, THAT TA JUST WANTED AN 8-BIT VERSION OF THIS COMPUTER. BUT SO THEY COULD KEEP THE RIGHTS TO DEVELOP AND SELL THE 16-BIT VERSION ON THEIR OWN.
IN 1972 THE DEVELOPMENT OF THE 8-BIT COMPUTER FOR TA WAS FINISHED AND THE NEW UNIVERSAL COMPUTER TA 1000 BECAME A BIG SUCCESS FOR TA.
THE SAME YEAR, THE MÜLLERS FOUNDED THE COMPUTER TECHNIK MÜLLER GMBH - CTM - TO START THE DEVELOPMENT ON THE 16-BIT COMPUTER, AND THE CTM 70 COULD BE INTRODUCED ON THE HANNOVER FAIR OF 1972.
ILSE MÜLLER FELT THAT A COMPUTER, WITH WHICH HUMANS INTERACT DIRECTLY (KEYBOARD FOR INPUT, CRT SCREEN FOR OUTPUT) HAS TO HAVE A SPECIAL NON TECHNICAL DESIGN, TOO. SO SHE TASKED HARTMUT ESSLINGER WITH THE DESIGN OF THIS COMPUTER (HIS FIRST COMPUTER TO DESIGN, LATER HE ALSO WORKED FOR APPLE...), WHICH WON THE "DIE GUTE INDUSTRIEFORM" AWARD, WHICH LATER BECAME THE IF IDUSTRIE FORUM DESIGN AWARD.
WITH THIS GREAT COMPUTER AND A HANDFUL GOOD EMPLOYEES, THE SUCCESS BEGAN FOR CTM.
BUT FOR A SMALL COMPUTER COMPANY LIFE ISN'T EASY AND SO AFTER SOME TIME AND SOME BAD LUCK CTM GOT IN FINANCIAL TROUBLE AND HAD TO LOOK FOR A ADDITIONAL INVESTOR. IN 1974 DIEHL DATENSYSTEME BOUGHT 51% OF CTM.
IN 1975 SOME NEW COMPUTER MODELS WERE INTRODUCED: THE CTM 70/600, CTM 70/700 AND CTM 70/800 (AKA CTM 600, CTM 700 AND CTM 800).
IN 1976 THE MULTI USER COMPUTER SYSTEM CTM 70/900 COMPLETED THE PRODUCT LINE. THE ALSO CTM CALLED 900 COULD BE EQUIPPED WITH UP TO 128KB RAM AND COULD HANDLE UP TO 16 USERS / WORKSTATIONS. AS OUTSTANDIG MULTI TASKING OPERATING SYSTEM CTM DEVELOPED ITOS (INTERACTIVE TERMINAL OPERATING SYSTEM), WHICH ALREADY HAD FULL WAN/ LAN SUPPORT.
DIEHL (DDS) GOT IN FINANCIAL TROUBLE BY OWN FAULT AND SO PLANS TO SELL THE WHOLE COMPANY WERE MADE IN 1977. BUT NOT BEFORE 1979 TRIUMPH ADLER BOUGHT DIEHL, AND THIS WAYS ALSO THE HALF OF CTM.
AT THE BEGINNING OF THE EIGHTIES, THE SUCCESSFUL 32-BIT COMPUTER SYSTEMS 9016 AND 9032 WERE INTRODUCED.
DUE TO CONTINOUS CONFLICTS WITH DIEHL (DDS), AND STRANGE MISMANAGEMENT OF THE DIEHL MANAGERS, THE MÜLLERS LEFT CTM IN 1982, AND SOLD THEIR REMAINING 49% TO DIEHL IN 1984.
IN 1985 DIEHL SOLD THESE 49% TO STANDARD ELEKTRIK LORENZ AG (SEL) AND IN 1986 THE REMAINING 51%.
ALTHOUGH 1987 WAS A VERY SUCCESSFUL YEAR FOR CTM, SEL NEEDED JUST A FEW YEARS WITH CONTINOUS MISMANAGEMENT TO RUN DOWN CTM AND IN 1989 IT WAS SOLD FOR 1 DM (DEUTSCHE MARK) TO THE FORMER COMMODORE MANAGER HARALD SPEYER AND WALTER BARTOLOMAE.
CTM WAS RENEMAED AFTER THEIR SUCCESSFUL OPERATION SYSTEM TO ITOS GMBH IN 1990.
ITOS WAS SOLD TO THE PEACOCK AG IN 1993, WHICH AGAIN WAS BOUGHT BY MAXDATA IN 1997... THAT TIME THE LAST COMPUTERS WHICH WERE ITOS-LABLED WERE OFFERED.
