THE CTM 70 IS A 16-BIT UNIVERSAL / OFFICE / MULTI PURPOSE COMPUTER - DEPENDING ON ITS CONFIGURATION.
IT WAS USED AS COMPUTER SYSTEM FOR SMALL AND MID SIZE COMPANIES.
WITH A POSSIBLE CONFIGURATION OF 64KB (LATER UP TO 128KB) OF RAM, A KEYBOARD, A CRT DISPLAY AND DOT MATRIX PRINTER AS OUTPUT AND AN EXTERNAL HARDDISK AS WELL AS THE INNOVATIVE DESIGN, IT WAS QUITE POWERFUL AND MODERN FOR ITS TIME (1972!)
BECAUSE CTM WASN'T THAT HUGE ENTERPRISE AND THE CTM 70 WAS THEIR FIRST BABY, NOT SO MANY OF THESE COMPUTERS WERE BUILT, AND ONLY FEW HAVE SURVIVED.
I AM LOOKING FOR ANY INFORMATION OR PARTS FOR THE CTM 70 OR COMPLETE SYSTEMS!
PLEASE REPORT ALSO ANY KNOWN SURVIVORS TO ME!
THIS PAGE COVERS THE CTM 70 SYSTEM OF JOSEF BICHLMEIER AT VILSHOFEN, GERMNAY.
