Sinclair User, often abbreviated SU, was a magazine dedicated to the Sinclair Research range of home computers, most specifically the ZX Spectrum (while also occasionally covering arcade games). Initially published by ECC Publications, and later EMAP, it was published in the UK between 1982 and 1993, and was the longest running Sinclair-based magazine.
Like many similar magazines, it contained news, game reviews, previews, tips, help guides, regular columns, readers' letters and cover-mounted game demos.
In May 1992 the former rival publication CRASH was notionally subsumed into Sinclair User but in practice this meant little more than the addition of the Crash! logo to the magazine's cover page.
In earlier years, the magazine built up personality cults around some of its "hilariously" monikered staff, including Bill "Incorruptible" Scolding, Jon "Disgusting" Gilbert, Chris "Lunchbreaks" Bourne, Claire "Ligger" Edgely, Richard Price (writer of the "Gordo Greatbelly" adventure tips section), and columnist Andrew Hewson (founder of Hewson Consultants software).
