''Poly-Play'' ran on a [[U880]], a clone of the [[Zilog Z80]] [[Central processing unit|CPU]], which was clocked at 2.457600 [[Hertz|MHz]] and a custom sound chip. Its display ran at a resolution of 512*256 at 50 [[Hertz|Hz]] and supported a palette of ten colours, though it could also use coloured overlays. The machine's coin slot was designed for 50 [[Pfennig]], but it was flawed - the pressure sensor could be deceived by pressing a 1-Pfennig coin very sharply into the top of the slot. However, this was largely tolerated because the machine was not a [[Capitalism|capitalistic]] commercial venture, but a state-owned product found predominantly in [[Free German Trade Union Federation|FDGB]] holiday homes, youth [[hostel]]s and [[non-profit]] clubs. The machine ran with a deactivated coin slot in many youth clubs. However, the free play often caused large crowds to form around it, which incited their reactivation.

A ''Poly-Play'' machine was on display in the [[Museum of Computing]] in [[Swindon]], England in 2004.<ref name="bbc"/> From 2005, the same machine was part of the touring video game show [[Game On (exhibition)|Game On]] and was exhibited in multiple museums, such as the [[Museum of Science and Industry (Chicago)|Museum of Science and Industry]] in [[Chicago]] and the [[Science Museum, London|Science Museum]] in [[London]].<ref>{{cite web|url=http://www.andys-arcade.net/personal/polyplay/polyplay.htm|title=Poly Play Information|author=Andy Welburn|publisher=andys-arcade|accessdate=2015-04-03}}</ref><ref>{{cite web|url=http://www.historyoftechnology.org/eTC/v48no3/schmitt.html|title=Exhibit Review: Half a Century of Digital Gaming, Game On|author=Stefan Schmitt|publisher=[[Society for the History of Technology]]|archiveurl=https://web.archive.org/web/20080518094041/http://www.historyoftechnology.org/eTC/v48no3/schmitt.html|archivedate=2008-05-18|accessdate=2015-04-03}}</ref> Two machines can also be seen at RetroGames e.V. in Germany.<ref>[http://www.retrogames.info/arcade/show/426 Poly Play VEB Polytechnik – 1986] - [http://www.retrogames.info ''RetroGames e.V.''] (last access 2011-01-20)</ref> It is also prominently on display at the [[Computerspielemuseum Berlin]].<ref>{{cite web|url=http://www.computerspielemuseum.de/1293_Poly_Play_videogame_machine.htm|title=Poly-Play videogame machine|date=20 December 2000 |publisher=[[Computerspielemuseum Berlin]]|accessdate=2015-04-03}}</ref>
