The D1 (actually "“programmable computer D1"” (Dresden 1)) was the first computer of the GDR developed in self-development.

It was sketched and built between 1950 and 1956, to the TH Dresden. Its technical designer is Professor Nikolaus Joachim Lehmann, father of many computers from Dresden.

The D1 was a tube computer. With its about 760 electron tubes could it 100-200 arithmetic operations per second implement. For the data retention a magnetic drum served which 2100 words stored. A word corresponded thereby to 72 bits or 3 instructions. In addition the D1 already had a assembler-similar programming.

Successors of the D1 were D2, D3 and D4.
