The Zuse Z23 was a transistorized computer first delivered in 1961, designed by the Zuse KG company. A total of 98 units were sold to commercial and academic customers up until 1967. It had a 40-bit word length and used an 8192 word drum memory as main storage, with 256 words of rapid-access ferrite memory. It operated on fixed and floating-point binary numbers. Fixed-point addition took 0.3 milliseconds, a fixed point multiplication took 10.3 milliseconds. It was similar in internal design to the earlier vacuum tube Z22. Related variants were the Z25 and Z26 models.[1]

The Z23 used about 2700 transistors and 7700 diodes. Memory was magnetic-core memory.[2] The Z23 had an Algol 60 compiler. It had a basic clock speed of 150 kHz and consumed about 4000 watts of electric power. An improved version Z23V was released in 1965, with expanded memory and a higher processing speed.

The Z23 weighed about 1,000 kilograms (1.0 t; 1.1 short tons).[3]
