WANDERER Conti core memory - The world's first printing electonical desktop calculator. It uses threaded ROM for very simple and solid programs.
FRIDEN 130, FRIDEN 132 delay line memory - The world's first desk calculator with display on cathode ray tube; 4 registers are displayed (with germanium transistors). Type 132 is featured with automatic square root calculation.
DIEHL Combitron delay line memory punchcard reader and puncher Germany's first freely programmable desk calculator.
The complete version is extremely rare. The device's calculator features only 130 transistors. The operating system is internally booted from metallic punchcards. Rarity!
WANG 320 S[1966/67] core memory punchcard reader, manual punchcard reader One of the world's first scientific programmable desktop calculators. Extremely rare. 2 of 4 pluggable keyboards. Pure transistor technology. Very fast computation of exponents and logarithms.
WANG 700[1969/70] 2KB core memory Complex printer (standalone device) that can plot, too. Mark Sense Card Reader, punchcard reader, DIN A0 flatbed plotter, additionally alphanumerical keyboard, Microface, double cassette drive with formated bands. Milestone of computer engineering! First IC-technology (DTL, TTL). Very intricately threaded ROM. Many years the world's fastest desk calculator. Big doublespaced display featuring nixie tubes (x-, y- Register), program storage on cassetts. Extremely expensive device (28.000 DM + many more than 50.000 DM for periphery). Very rare.
WANG 550 semiconductor memory - trimmed-down version of the WANG 700 - single-line nixie tubes display, thermal printer, cassette drive.
WANG 600 semiconductor memory printer/plotter, Mark Sense Card Reader Perfomance-related viewn it is set between the WANG 700 and the WANG 500. Still with threaded ROM. Programs on cassettes.
