A desktop suite written in 1988 by Urs Koenig of Switzerland. Marketed and maintained between 1989 and 1995 by COWO Electronic with initial distributors TK Computerware in the UK and QLympic Computer Systems in Germany. Later on Software 87 and Dilwyn Jones Computing(DJC) acted as resellers.

Initially conceived as ThorDesk for the powerful CST Thor XVI launched in September 1987, the intention was to bundle it with every shipped Thor computer. In 1989 it became clear that the Thor story would end, so the decision was made to expand the design in a way (by adding Thor XVI emulators for each platform) that it would run on all other QDOS compatible computers from the original SINCLAIR QL with 128KB RAM and Microdrives to the ATARI ST with QL-Emulator. The QTop suite also runs on the COMMODORE AMIGA with QL emulation without any restrictions, which is more than what can be said of most other QL software. The more expanded a QL system is, the better QTop performs.

In January 1998 Urs Koenig declared QTop and other COWO Electronic software packages as freeware. The software was then submitted as is to Gerhard Plavec for inclusion on the QL-PD/CD-R which was the first in the series of QL related CDROMs. In January 2002 and updated edition named QTop/E was announced for the upcoming QL software distribution called QL/E. The latest version can be found on The Distribution, see DVDs.
