This Video shows an IBM Memory Typewriter playing out Track 51 (Printer Exerciser Text to test all machine functions).
The IBM Memory Typewriter was announced in March 1974. Whereas this machine was first installed in 1978 and was used in a doctors office until the end of the year 2011!
We have fully overhauled this typewriter in December 2012.
The IBM Memory Typewriter was announced March 1974. It was packaged in one set of covers that fit on a desktop, and could be classified as the first IBM "electronic typewriter." It has a 4-Kbyte electronic memory (MOSFET shift register) and a tape loop under the cover which is capable of storing 4000 Character files on fifty tracks. The tape is 1.5 inches wide, and runs at a speed of 12.5 ips, and records at a density of 800 bits per inch (bpi). In 1978 the Memory Typewriter was also available with a tape loop capable of storing 100 tracks.
The tag price of the Memory 50 back in the 70's was around Swiss Franc 16'000.00 in Switzerland, maybe thats one of the reasons why this machine is hard to find nowadays.
Dieses Video zeigt eine IBM Kugelkopf-Schreibmaschine 96M (umgangsprachlich Memory 50) die den sog. Printer Exerciser ausdruckt, mit dem alle Maschinenfunktionen getestet werden können.
Die IBM Memory 50 kam 1974 auf den Markt, wobei diese Maschine im Jahre 1978 in Betrieb genommen wurde und bis Ende 2010 in einer Arztpraxis in Deutschland eingesetzt wurde. Die Maschine wurde durch uns im Dezember 2012 komplett revidiert und auf Deutsch-Schweizer-Tastatur umgebaut.
Die Memory 50 kostete in den 70er Jahren um die 16'000.00 Schweizer Franken.
