Robotron Z1013
home computer
The MRB Z 1013 (German: Mikrorechnerbausatz, lit. 'microcomputer kit') was an East German single-board computer produced by VEB Robotron Riesa, which was primarily intended for private use and educational institutions. It was powered by a U880 processor (a Z80 clone) and sold together with a membrane (flat foil) keyboard. Initially, the kit was equipped with 16 kilobytes of DRAM, which was later replaced by a 64 KB version.
The kits first became available for sale in 1985 and were distributed in a unique way at the time. To purchase it, buyers had to send a postcard to the Robotron shop in Erfurt and wait six to twelve months and then to pick the kits up in person.
The package contained the assembled and tested motherboard, a membrane keyboard, various small parts and detailed technical documentation. This basic kit was shipped without power supply or casing for the PCB. Most users tended to program the kit using the BASIC interpreter, which was loadable from compact cassette or by using a ROM cartridge. The BASIC interpreter contained a common core binary, which was identical across home computer models. In consequence, programs were widely compatible among different models of GDR-manufactured computers despite differences in capabilities.
Robotron was also the manufacturer of another line of computers, the Z 9001, KC 85/1 and KC 87, which shared some of the same expansion modules – offering more options also for Z 1013.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Robotron Z1013”, the useful work is to connect “home computer” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Mar 15, 2026. The linked authority identifier is Q135831. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1013 and 1985.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
